Quick Reference to Linux Commands

Many of us find it very difficult to remember the general linux commands(especially for a person with short term memory loss, like me ). Thus, everytime I Google for a particular command. I then thought of a page which will give a quick reference to the most common linux commands. Here it is–>

I will keep updating this page whenever i come across a command which is not included. I would request viewers to help me  increase the number…..

1. adduser :- This command will automatically add a new user to the system. The Bash script can be found in /usr/sbin if it needs to be changes.

2. alias :-

—–alias help=man – The alias command allows you to substitute a new name for a command.

—–alias long=ls -al – An alias can also contain command line options. Unless the alias definition is included in your

.login file it is only temporary.

3. apropos :- Display command names based on keyword search

4. at :-

—–at 1:23 lp /home/index.html – The at command runs a list of commands at a specified time (e.g. print @ 1:23).

—–at 1:50 echo “lp Job Done” – This uses the echo command to send a message at 1:50 saying a print job is done.

—–at -l – Lists all scheduled jobs; an alias for the atq command.

—–at -d 5555 – This will cancel job number 5555; an alias for the atrm command.
