The alias command can be useful if you want to create a 'shortcut' to a command.
The format is alias name='command'
> alias home='cd /home/dave/public_html'
This will create an alias called home which will put you in the /home/dave/public_html directory whenever you type home at the command prompt. You can alias any command you want, and include options for the command.
> alias list='ls -la'
This will create an alias called list, which will use the ls command to print a long-style listing of all files in the current directory (the -l gives a long-style list, and the -a shows all files - including hidden files).

To see a list of aliases set up on your linux box, just type alias at the prompt.

You can see there are a few already set up on a default Redhat 9 installation.
To remove an alias, use the unalias command.
