- Text based methods that require familiarity with the terminal. The apt-get program is a command-line package manager, which is easy to operate and in some cases is quicker to use and more powerful than the graphical tools. sudo apt-get install <package_name >
- GDebi is a simple graphical tool to install .deb files. It automatically checks packages for their dependencies and will try to download them from the Ubuntu software repositories if possible. To install GDebi, open a Terminal and type: sudo apt-get install gdebi
- dpkg is a command-line tool used to install .deb files. To install a package with dpkg, open a Terminal and type the following: cd directory
sudo dpkg -i package_name.deb
But in double quotation we have:
If we use backslash before special character we will have:
echo "Second argument is $2"
elif condition2 ; then
echo "Number of parameters is one"
elif [ $# = 2 ]; then
echo "Number of parameters is two"
echo "Number of parameters is more than two"
while [ $count -gt 0 ];do
- grep 'word' filename : search in the given file and returns lines which contain the word.

Which references can be:

- Unpack the downloaded file: gunzip -c otp_src_R15B.tar.gz | tar xf -ortar zxvf otp_src_R15B.tar.gz
- Move into the base directory:cd otp_src_R15B
- Set the environment variable (ERL_TOP) to find the absolute path of the installation: ERL_TOP="`pwd`"
- Set the Erlang/OTP system in the $PATH: PATH="$ERL_TOP/bin:$PATH"
- Set the LANG variable: LANG=C; export LANG
- Configure the build:
If you want to install Erlang in a specific path, you can use prefix as shown below:
- Build the Erlang/OTP package:make
- Install the Erlang/OTP package:sudo make install
- Run Erlang:erl
- Exit from Erlang shell:q().
