How to remove error: Your intltool is too old You need intltool 0.35.0 or later

First download intltool 0.35.0 or later from here -> Gotodownloadaddress

Now just follow following steps:

• Place the downloaded file in Home directory.
• Open terminal
• Type following command

 tar xvf intltool-0.35.5.tar.gz 

(It will extract files and create a folder in home directory)

I had downloaded intltool-0.35.5.tar.gz file so, you can change name as per your downloaded version of file.

 Follow given steps to install this package :

  1. `cd intltool-0.35.5' 

       to move the directory containing the package's source code and type
     `./configure' to configure the package for your system.  If you're
     using `csh' on an old version of System V, you might need to type
     `sh ./configure' instead to prevent `csh' from trying to execute
     `configure' itself.

     Running `configure' takes awhile.  While running, it prints some
     messages telling which features it is checking for.

  2. Type `make' to compile the package.

  3. Optionally, type `make check' to run any self-tests that come with
     the package.

  4. Type `make install' to install the programs and any data files and
     documentation.

  5. You can remove the program binaries and object files from the
      source code directory by typing `make clean'.  
      To also remove the files that `configure' created 
      (so you can compile the package for a different kind of computer), 
      type `make distclean'.  There is also a `make maintainer-clean' target, 
      but that is intended mainly for the package's developers.  
      If you use it, you may have to get all sorts of other programs in 
      order to regenerate files that came with the distribution.

Install/Remove GNOME Desktop Environment in Kali Linux

I have also written article on how to install/remove KDE Desktop Environments in Kali Linux now this is another article.
GNOME is a desktop environment which is composed entirely of free and open-source software and targets to be cross-platform, i.e. run on multiple operating systems, its main focus being those based on the Linux kernel.
In the default configuration of GNOME, the desktop has a top panel holding (from left to right) an activities button, clock, system status area and user menu. Clicking on the activities button or moving one's mouse to the top-left hot corner brings one to the overview.

• The system status area holds various system indicators, such as those for volume, Bluetooth, network, battery, and accessibility.
• The user menu holds a chat-availability indicator, shortcuts to system settings, and session actions such as logging out, switching users, locking the screen, or suspending the computer.
• The overview (accessed by clicking on the activities button in the top panel, or touching the top-left hot corner) shows the window picker, the workspace changer on the right, the dash on the left, a windows button, an applications button, and a search bar. While in the overview, users can click on the windows and application buttons just under the top panel to switch between the window picker and the application picker.
• The window picker gives users a quick overview of current activities, and provides a way to switch to other open windows or close multiple windows easily.
• The application picker provides an easy way to launch applications.
• The dash houses shortcuts to favorite applications and open windows.

How to Fix PulseAudio configured for per-user sessions … (warning) in Kali Linux and Debian

PulseAudio is a free cross-platform network sound server, targeting mostly POSIX-compliant operating systems meaning that it is a proxy for your sound applications. It allows you to do advanced operations on your sound data as it passes between your application and your hardware. Things like transferring the audio to a different machine, changing the sample format or channel count and mixing several sounds into one are easily achieved using a sound server.

PulseAudio is available in recent versions of several major linux distributions such as Kali Linux and debian.

Features

The main features includes:

1. Per-application volume controls
2. An extensible plugin architecture with support for loadable modules
3. Compatibility with many popular audio applications
4. Support for multiple audio sources and sinks
5. Low-latency operation and latency measurement
6. A zero-copy memory architecture for processor resource efficiency
7. Ability to discover other computers using PulseAudio on the local network and play sound through their speakers directly
8. Ability to change which output device an application plays sound through while the application is playing sound (without the application needing to support this, and indeed without even being aware that this happened)
9. A command-line interface with scripting capabilities
10. A sound daemon with command line reconfiguration capabilities
11. Built-in sample conversion and resampling capabilities
12. The ability to combine multiple sound cards into one
13. The ability to synchronize multiple playback streams
14. Bluetooth audio devices with dynamic detection
15. The ability to enable system wide equalization

The Warning Message during boot

My Kali Linux shows me this warning:

[warn] PulseAudio configured for per-user sessions ... (warning).

NOTE-Debian variants also shows similar warning during boot.

To fix this problem do as follows:

Open terminal and copy the following 

leafpad /etc/default/pulseaudio

Find this line:

PULSEAUDIO_SYSTEM_START=0

Replace 0 with 1

PULSEAUDIO_SYSTEM_START=1

where,
0 = don’t start in system mode, 1 = start in system mode

Finally Reboot(Restart)

You can also test the .zip file ( i.e. make sure its OK or not) by the following command.
The command prints a summary message indicating whether it is usable or broken 

unzip -tq filename.zip

To extract an individual file from a zip archive 

( Let us suppose the name of the file as fun.doc) 

unzip filename.zip fun.txt

Extract all files of the zip into the /tmp directory  

unzip filename.zip -d /tmp

List the files of the archive without unzipping them

How to open RAR File or extract RAR Files under Linux or UNIX

RAR files are in compressed archive format, if you have downloaded rar files from the Internet, you need to unpack or unrar them (extract rar files). RAR is a proprietary file format for data compression and archiving. The command used to extract these files is called "unrar". By default, unrar is not being installed on Linux, FreeBSD or UNIX like operating system. You can install unrar command with the help of apt-get or yum command.

Note- Kali Linux users can directly use unrar command as it is pre-installed in it.

$ cd /tmp
$ wget http://www.rarlab.com/rar/rarlinux-3.6.0.tar.gz

Next, untar file, enter:
$ tar -zxvf rarlinux-3.6.0.tar.gz

Both unrar and rar commands are located in rar sub-directory. Just cd to rar directory, type:
$ cd rar
$ ./unrar

Now copy rar and unrar file to /bin directory, type:
# cp rar unrar /bin

How To Use unrar Command

The unrar command supports various options, below are common options that you need to for extracting files.
