Creating alias in bash
You can alias any command in your .bashrc file to create shortcut.
For ex – alias l=’ls -ltr’ will create a alias for ls command with -ltr options. Now use only l to invoke this command.
Combine two or more commands in one alias,
alias cdh=”cd <home>; ls -l”
You can see aliases set by you by invoking ‘alias’ command in shell.
A more complex example for creating a shortcut,
rmdir()
{
rm -rf $1 > /dev/null &
}
$> rmdir test will remove test directory.
