How to Check / Find MAC Address on Linux Mint

How to Check or Find MAC Address on Linux Mint? There are two methods to find your current MAC Address: First you can know MAC Address using ifconfig; Second you can find mac address linux without ifconfig.

What is MAC Adress ?

If you are connected to the network (both for local or internet) using cable you certainly have a device called NIC (Network Interface Card). And if you are connected using Wi-Fi device you also have the Wi-Fi device.

Every NIC has a hardware address that's known as a MAC, for Media Access Control. Where IP addresses are associated with TCP/IP (networking software), MAC addresses are linked to the hardware of network adapters.

A MAC address is given to a network adapter when it is manufactured. It is hardwired or hard-coded onto your computer's network interface card (NIC) and is unique to it. Something called the ARP (Address Resolution Protocol) translates an IP address into a MAC address. The ARP is like a passport that takes data from an IP address through an actual piece of computer hardware.

Once again, that's hardware and software working together, IP addresses and MAC addresses working together.

How to Check / Find MAC Address on Linux Mint

The original MAC address can be found using the same technique the network card driver does -but you can find current MAC address using Terminal as follow:

Find MAC Address Using IFCONFIG

ifconfig is a small tool for Linux designed to show the current MAC address that you are using now. This tool is available by default on your system, and you can know your current MAC address by typing command ifconfig -a

You may have a result like this :
know mac address linux find mac address linux check mac address linux find mac address linux command line see mac address linux determine mac address linux find mac address linux mint check mac address linux command find mac address linux terminal find mac address linux without ifconfig find mac address linux command find mac address linux ubuntu find mac address linux fedora find mac address linux redhat find mac address linux server find mac address linux network find mac address linux vm check mac address linux centos find mac address linux machine know my mac address linux find out mac address linux find mac address arch linux find mac address on linux box mac address linux bash

Explanation :
  1. The eth0 is NIC (Network Interface Card) when your computer connected to a local network using a RJ-45 connector cable type. For my result above is inactive because i am using a Wi-Fi connection.
  2. The wlan0 show the MAC address used by Wi-Fi device. This is my current MAC address and you can show there is number n RX packets. Now we will check MAC address without ifconfig.

Find MAC Address Using ETHTOOL

ethtool is an alternative Linux apps for ifconfig, and you need to install it first to use.
How to install ethtool? You only need open your Terminal and type sudo apt-get install ethtool

How to run ethtool to know MAC address? You have to decide where device that MAC address number you want to know; Is your NIC card or Wi-Fi device ?

Open your Terminal and type ethtool -eth0 in order to know your MAC number on your NIC card
Or type ethtool -wlan0 in order to know the MAC address for the Wi-Fi device. That is very simple! Try to see that picture above you will see the same result of the MAC address from different MAC retrieval method.

Ways to Split Large File for CSV or TXT on Linux Mint

Ways to Split Large File for CSV or TXT on Linux Mint --The text based file contain many rows of data and you can split them into separated file easily on Linux. How you can split large text file into multiple files on Linux let's follow these guide.

Split a large file into smaller files on Linux can be done with Terminal, the command promt on Linux and you can also Keep Header Row of the file.

For an example you have a CSV file which contain around 1000 rows; each row having 5 columns. You want to break this CSV file into 10 CSV files of 100 records each. (Each having same CSV header as present in original CSV). How to solve this case ?

This is  the result of files that I have tried using these method:
split large file linux split large file linux command divide large file linux split large text file linux split large log file linux split large csv file linux split large sql file linux split large binary file linux split large xml file linux split large file into chunks linux linux split large file into parts split large file into smaller files linux linux split large file in two linux split large file by lines split large file into multiple files linux split large text file into multiple files linux split large text file into smaller files linux split large xml file into smaller files linux linux split large tar file linux split compress large file split a large file linux split a large text file linux split a large file into smaller files linux linux split and compress large file


Ways to Split Large File for CSV or TXT on Linux Mint

Linux has a great little utility called split, which can take a file and split it into chunks of whatever size you want, eg 100 line chunks.

However, for CSV files etc, each chunk generally needs to have the header row in there. Unfortunately the split command doesn’t have an option for that. However with a little bit more code you can achieve it.

If yuo have CSV file called hotel.csv which contain 1000 rows; each row having 5 columns. You want to break this CSV file into 10 CSV files of 100 records each.

Place that file into your home directory and open Terminal (press Ctrl + Alt + T), then type the following command :
tail -n +2 hotel.csv | split -l 100 - split_

Press enter then enter this command :
for file in split_*; do head -n 1 hotel.csv > tmp_file; cat $file >> tmp_file; mv -f tmp_file $file; done

Press enter again, for the result you can see the created new file named split_aa.csv, split_ab.csv, ...etc on your home directory. Now you have finished split large text file into smaller files on Linux.

You can also execute the command one by one per line into Terminal as follow:
tail -n +2 hotel.csv | split -l 100 - split_
for file in split_*
do
    head -n 1 hotel.csv > tmp_file
    cat $file >> tmp_file
    mv -f tmp_file $file
done

Create Backup with Back In Time Linux Backup Solution

Create Linux System Backup with Back In Time Linux Backup Solution. Back In Time is a simple backup tool for Linux inspired from “flyback project” and “TimeVault”. The backup is done by taking snapshots of a set of directories. Snapshots are a copy of a directory structure or file at a certain point in time.

Snapshots are protected from accidental deletion or modification since they are read-only by default. The super-user can delete intermediate snapshots to save space, but files and directories that existed before or after the deletion will still be accessible.

Back In Time is a simple backup tool for Linux inspired from “flyback project” and “TimeVault”. The backup is done by taking snapshots of a specified set of directories.

Currently there are two GUI available for this Back In Time: Gnome and KDE 4 (>= 4.1).
All you have to do is configure:
  1. Where to save snapshot
  2. What directories to backup
  3. When backup should be done (manual, every hour, every day, every week, every month)
Now we have a backup solution software equivalent to Apple’s TimeMachine on Linux called Back In Time. The alternative applications for Linux to hande Linux data backup solution similiar to the TimeValut and FlyBack. Both of them are discontinue program so the Back In Time is the best backup solution tool for Linux today.

What is the Linux Program Called Back In Time Really ?

Keep in mind that Back In Time is just a GUI. The real magic is done by rsync (take snapshots and restore), diff (check if something changed) and cp (make hard links).

Back In Time acts as a “user mode” backup system. This means that you can backup/restore only folders you have write access to (actually you can backup read-only folders, but you can’t restore them).

create linux backup create linux backup image create linux backup server create linux backup script linux create backup file linux create backup user linux create backup tar linux create backup directory linux create backup file with date linux create backup root user linux create backup partition howto linux backup create bootable linux backup howto backup linux server howto backup linux system howto backup linux partition create iso backup linux linux create incremental backups linux create full backup linux create database backup linux create folder backup create a linux backup image create a linux backup server create a backup linux linux create a backup of a file create a backup user linux create automatic backup script linux linux make backup copy of file linux create backup disk image linux make backup file linux make full backup

If you want to run it as root you need to use “su” (command line), “gksu” (Gnome) or “kdesudo” (KDE).

A new snapshot is created only if something changed since the last snapshot (if any).
A snapshot contains all the files from the selected directories (except for exclude patterns). In order to reduce disk space it use hard-links (if possible) between snapshots for unchanged files. This way a file of 10 MiB, unchanged for 10 snapshots, will use only 10MiB on the disk.

When you restore a file ‘A’, if it already exists on the file system it will be renamed to ‘A.backup.<current data>’.
For automatic backup it use “cron” so there is no need for a daemon, but “cron” must be running.
Starting from version 0.9.24 permissions and user/group are stored in a special file. This way you can even save/restore files from a NTFS/FAT drive without losing this informations (NOTE: FAT don’t support hard-links).

How to Install Back In Time on Linux - The Apple Time Machine Alternative

You can install this great program by adding PPA to your Linux system. Open your Terminal and type these commands, please enter one per line:
sudo add-apt-repository
ppa:bit-team/stable
sudo apt-get install backintime-gnome
 

NOTE: You can also install Back In Time from Software Center, for Linux Mint user go to Start Menu >> Administration >> Software Manager then type and search backintime, you will find it the install. But please note if you install from Software Center, you will get an older version of this software.

Now you can open Back In Time program after install on Linux by clicking Start Menu >> Administration >> Back In Time (root)

Back In Time Review Program on Linux

This is the best backup tool for the Linux system such as restore point on Windows but it is more than that. Back In Time does incremental backups so it is fast. the best thing is that the backups can be viewed with just a file browser (including older snapshots) so when disaster strikes, there is no complicated installation and configuration required to access the backups on another computer / the repaired computer.

How to Use OCR in Linux - Extract Text From PDF Image

How to Use OCR in Linux - Extract Text From PDF Image. The gImageReader is a graphical GTK frontend to tesseract-ocr, a free software optical character recognition (OCR) engine.

Tesseract is a raw OCR engine, with no document layout analysis, no output formatting and no graphical user interface (GUI). If you want a GUI version of Tesseract you can install YAGF, the front end program for Tesseract OCR.

gImageReader processes an image or PDF file from which it creates text. It supports selecting columns and parts of the document, it can open multipage PDF files or images, supports all formats, can transmit a selected area to Tesseract for recognition and spell check the output.

Install Tesseract OCR in Linux

With the discontinuation of downloads at code.google.com, new source downloads will be posted to GoogleDrive. Other download folders will be setup as new files are uploaded, and the original Downloads page will go away

Warning: you must add the PPA, install the latest Tesseract and then disable the PPA as it contains a lot of bleeding edge packages!

Add the PPA and install Tesseract OCR 3.0 SVN:
sudo add-apt-repository ppa:alex-p/notesalexp
sudo apt-get update
sudo apt-get install tesseract-ocr tesseract-ocr-eng

Or you can install using Linux installer file here http://sourceforge.net/projects/gimagereader/

How to Use OCR in Linux - Extract Text From PDF Image convert image to text linux convert picture to text linux convert pdf image to text linux convert linux add text to image convert text file to image linux convert image to text in linux convert image to text linux

You can install some extra languages from this PPA, such as Bulgarian, Catalan, Czech, Danish, German, Greek, Finnish, Indonesian, Hungarian, Italian, Dutch, Polish, Romanian, Spanish and so on. Simply search for "tesseract-ocr" in Synaptic and you should easily find all these packages - install the ones you'll need later on.

Now you must disable the PPA: press ALT + F2 and enter:
gksu software-properties-gtk

Then, on the "Other Software" tab look for the line(s) that says "http://ppa.launchpad.net/alex-p/notesalexp" and either disable it or delete it.

gImageReader

gImageReader is available for Linux and Windows and can be downloaded from HERE (.deb, .rpm and .exe files are available).

To use gImageReader, select the PDF or image you want to extract the text from and click "Recognize all" for the whole page or use your mouse to draw a selection and then click "Recognize selection" to extract only a part of the document.

If you've installed the Tesseract Ocr language for the PDF or image you're trying to open, gImageReader will automatically detect the language.

2 Best Software to Design Posters, Brochures in Linux

2 Best Software to Design Posters, Brochures, Flyer in Linux. What software should you use to design a poster for linux? There is best free software to design a poster for linux: GIMP and Inkscape.

2 Best Software to Design Posters, Brochures, Flyer in Linux

If you are looking for linux software to make poster design and print it out you have two choice that really depends on your preference; If you like to use vector software such as Inkscape which will allow to design like if you were to be using Adobe illustrator.

Then the other route would be to use a raster based software such as the GIMP which allows you to design like if you were to be using Adobe Photoshop.

Vector = Lines and Curves
Scales better if you want to later on resize your image but only works well when creating original works without any photos.

Raster = Dots per inch or DPI
Mostly used for modifying photos or creating digital art work with photos. This works great if your artwork will make use of heavy photo editing/manipulation.

software used to design posters in linux software to design movie posters in linux easy software to design posters in linux download software to design posters in linux software to design scientific posters in linux software untuk design poster in linux software poster design linux software to design a poster in linux best software to design a poster for linux software used to design a poster for linux best free software to design a poster for linux what software can i use to design a poster for linux what software should i use to design a poster for linux

Note: In inkscape you can import raster images and add some effects and export your designs as raster images with the .png file extension. inkscape can also export or save your designs as a PDF file.

Vector graphic programs are really strong on the layout, but take a lot of fiddling. Most academic work doesn't require extensive use of a vector graphics program, so most people are not familiar. There is little added benefit of learning one.

Desktop publishing software is really designed for making posters and other complicated layout (think magazines and brochures). There is almost no reason for most academics to master a desktop publishing software.

For GIMP, it is installed by default on Linux Mint and be used as Photoshop. Meanwhile the Inkscape you have to install it first on your machine.

How to Create ISO Image From File Using Linux Terminal

How to Create ISO Image From File Using Linux Terminal with GenIsoImage. Besides of using K3B the burning software for Linux, you can use GenIsoImage to create ISO file in Linux easily. Here is how to install GenIsoImage and How to create ISO file.

Genisoimage is a pre-mastering Linux software for creating iso file (ISO-9660 CD-ROM filesystem images), which can then be written to CD or DVD with any CD burner program, and it runs as command Line program in Terminal. Genisoimage includes support for making bootable "El Torito" CDs, as well as CDs with support for the Macintosh HFS filesystem.

The package also includes extra tools useful for working with ISO images:
  1. mkzftree - create ISO-9660 image with compressed contents
  2. dirsplit - easily separate large directory contents into disks of predefined size
  3. geteltorito - extract an El Torito boot image from a CD image

How to Install GenIsoImage in Linux Mint

GenIsoImage has been added into Ubuntu repository, so you can install GenIsoImage from Linux Terminal by executing:
sudo apt-get install genisoimage
 
create iso file from terminal with genisoimage create iso file ubuntu terminal create iso from terminal linux create iso file from a cd create iso file from audio cd create iso file from a folder create iso file from a file make iso file from audio cd make iso file from a cd create iso file android create iso file from bootable usb create iso file from bootable dvd create iso file from bootable usb drive make iso file from bin create iso file bootable create iso file by genisoimage

How to Create ISO Image From File Using Linux Terminal

You can create an ISO image from files in a directory. To create an ISO image from files within a directory is just as simple. State an output directory and name of the ISO to create, along with a source directory. For example:
genisoimage -o isofile.iso foldername
 
Notes:
If you want make iso file from a file or bulk file, you need to place the file(s) into one folder.
foldername subtitute with your folder you want to create iso file
isofile is a name given by you for your iso later

Time for generating iso file depends on how many files you want to create. Less files will generate faster. genisoimage is derived from mkisofs from the cdrtools 2.01.01a08 package from May 2006 (with few updates extracted from cdrtools 2.01.01a24 from March 2007) from .IR http://cdrecord.berlios.de/ , but is now part of the cdrkit suite, maintained by Joerg Jaspert, Eduard Bloch, Steve McIntyre, Peter Samuelson, Christian Fromme, Ben Hutchings, and other contributors. The maintainers can be contacted at debburn-devel@lists.alioth.debian.org, or see the cdrkit project web site at http://www.cdrkit.org/.

EASY WAY How to Scan Document in Linux Using Xsane

How to Scan Document and Photo in Linux Using Xsane Easily. This article will provide you an easy way to scan any document using XSane Scanning Program in Linux. We also provide an alternative to scan your document using LibreOffice Writer.

Xsane can be run as a stand-alone program or through the GIMP image manipulation program. In stand-alone mode, xsane can save an image to a file in a variety of image formats, serve as a frontend to a fax program, or send an image to a printer.

SANE stands for "Scanner Access Now Easy" and is an application programming interface (API) that provides standardized access to any raster image scanner hardware (flatbed scanner, hand-held scanner, video- and still-cameras, frame-grabbers, etc.). The SANE standard is free and its discussion and development are open to everybody.

The current source code is written to support several operating systems, including GNU/Linux, OS/2, Win32 and various Unices and is available under the GNU General Public License (commercial applications and backends are welcome, too, however).

1. How to Scan Document and Photo in Linux Using Xsane

Preparation: Make sure you have installed Xsane Image Scanning Program. To install it open your Software manager or Application Manager in Ubuntu, seaarch using keyword xsane and you will find it then isntall until finish. Once you've finished open your Xsane by clicking Start/Menu >> Graphics >> XSane Image Scanning Program
use scanner in linux, xsane image scanner linux how to scan a document scan documents document scanning scanning documents scan a document document scanning software scan document scanning a document how to scan documents document scan

How to use XSane Image Scanning Program in Linux :

  1. Check your scanner is connected and make sure to power it ON
  2. Put your document into the scanner
  3. Open XSane Application, the apps will detect your scanner automatically. Click Scan to start the scanning process
  4. If the scan complete, you can save the document into .jpg or .png or .bmp or you can also export it to PDF directly
Note : When sane does not automatically detect your scanner, it doesn't always mean that your scanner isn't going to work. Sometimes (especially with some older scanners) it just means that you will have to configure your scanner manually.

Adjust the settings as necessary for the document that you plan to scan. Text documents can often be scanned in black and white, while some scanning software may make allowances for scanning photos vs scanning posters. The software varies widely across brands and devices, so you will have to experiment.

2. How to Scan Document Using LibreOffice Writer

This will provide an alternative method to scan your document in an easy way. If you're not connected to the internet and not install the XSane yet you can LibreOffice to scan document or photo in Linux.

The History and Overview of Arch Linux

What is Arch Linux ?

Arch Linux is a Linux distribution for i686 and x86-64 computers. It is composed predominantly of free and open-source software, and supports community involvement. The design approach of the development team focuses on elegance, code correctness, minimalism, and simplicity, and expects the user to be willing to make some effort to understand the system's operation. A package manager written specifically for Arch Linux, pacman, is used to install, remove and update software packages.

Arch Linux uses a rolling release model, such that a regular system update is all that is needed to obtain the latest Arch software; the installation images released by the Arch team are simply up-to-date snapshots of the main system components.

Arch Linux focuses on simplicity of design, meaning that the main focus involves creating an environment that is straight forward and relatively easy for the user to understand directly, rather than providing polished point-and-click style management tools — the package manager, for example, does not have an official graphical front-end. This is largely achieved by encouraging the use of succinctly commented, clean configuration files that are arranged for quick access and editing. This has earned it a reputation as a distribution for "intermediate and advanced Linux users who aren't afraid of the command line"

Arch Linux Package Management

Pacman
To facilitate regular package changes, Pacman (abbreviated from "package manager") was developed by Judd Vinet to provide Arch with its own package manager able to track dependencies.

Arch Linux Logo

All packages are managed using the Pacman package manager. Pacman handles package installation, upgrades, removal and downgrades, and features automatic dependency resolution. The packages for Arch Linux are obtained from the Arch Linux package tree and are compiled for either i686 or x86-64 architectures. It uses binary packages in the tar.xz format, with .pkg placed before this to indicate that it is a Pacman package (giving .pkg.tar.xz).

Repositories
Currently, the following basic official binary repositories exist:
  • core, which contains all the packages needed to set up a base system
  • extra, which holds packages not required for the base system, including desktop environments and programs
  • community, which contains packages built and voted on by the community; includes packages that have sufficient votes and have been adopted by a "trusted user".
  • multilib, a centralized repository for x86_64 users to more readily support 32-bit applications in a 64-bit environment.
In addition, there also exist testing repositories that include binary package candidates for other repositories. Currently, the following testing repositories exist:
  • testing, with packages for core and extra.
  • community-testing, with packages for community.
  • multilib-testing, with packages for multilib.

The staging and community-staging repositories are used for some rebuilds to avoid broken packages in testing.

The unstable repository was dropped in July 2008 and most of the packages moved to other repositories. In addition to the official repositories, there are a number of unofficial user repositories.

The most well-known unofficial repository is the Arch User Repository, or AUR, hosted on the Arch Linux site. However, the AUR does not host binary packages, instead hosting a collection of build scripts known as PKGBUILDs.

Repository security
Until pacman version 4.0.0 Arch Linux's package manager lacked support for signed packages. Packages and metadata were not verified for authenticity by pacman during the download-install process. Without package authentication checking, tampered-with or malicious repository mirrors can compromise the integrity of a system. Pacman 4 allowed verification of the package database and packages, but it was disabled by default. In November 2011 package signing became mandatory for new package builds, and as of 21 March 2012 every official package is signed.

Arch Build System (ABS)
The Arch Build System (ABS) is a ports-like source packaging system that compiles source tarballs into binary packages, which are installed via Pacman. The Arch Build System provides a directory tree of shell scripts, called PKGBUILDs, that enable any and all official Arch packages to be customized and compiled.

Rebuilding the entire system using modified compiler flags is also supported by the Arch Build System. The Arch Build System makepkg tool can be used to create custom pkg.tar.xz packages from third-party sources. The resulting packages are also installable and trackable via Pacman.

Arch User Repository (AUR)
In addition to the repositories, the Arch User Repository (AUR) provides user-made PKGBUILD scripts for packages not included in the repositories. The PKGBUILD scripts simplify building from source by explicitly listing and checking for dependencies and configuring the install to match the Arch architecture.

The scripts are available for download from the Arch Linux web site. Arch User Repository helper programs can further streamline the downloading and building process. However, such tools that search, download and run PKGBUILD scripts automatically will never be included in the official repositories because of potential security risks.

Users can create packages compatible with pacman using the Arch Build System and custom PKGBUILD scripts. This functionality has helped support the Arch User Repository, which consists of user contributed packages to supplement the official repositories.

The Arch User Repository provides the community with packages that are not included in the repositories. Reasons include:
  1. License issues. Software that cannot be redistributed, but is free to use, can be included in the Arch User Repository since all that is hosted by the Arch Linux web site is a shell script that downloads the actual software from elsewhere. Examples include proprietary freeware such as Google Earth and RealPlayer.
  2. Modified official packages. The Arch User Repository also contains many variations on the official packaging as well as beta versions of software that is contained within the repositories as stable releases.
  3. Rarity of the software. Some new or rarely used programs have not been added to the official repositories (yet).
