Linux
Commands for Beginning
Server Administrators
Brought
to you by Mark Rais, senior editor ReallyLinux.com
Most new Linux administrator desire one easy to read list of the essential commands needed for daily server
management and maintenance. I've updated my beginner administrators command list below in hopes that it will help you quickly become
self sufficient in Linux server use.
Please feel free to LINK to this commands page, but please don't duplicate it elsewhere as I've tried hard to provide something useful to others.

You may also benefit from more basic commands such as:
beginner commands,
more advanced commands, and file
permissions.
Please consider running these administrator commands on occasion with the
--help parameter to read
through all of their options. For example try running the command: du
--help
Also note
that if a server command you run gives you an output that is far more
than one single screen, you can use the option |more (referred to as
pipe more). This will display the output one screen at a time. Press the space key for one page
at a time, and the enter key for one line at a time. For example: ps -A |more

Tool used to monitor who is on the
system and many other server related characteristics
Most common uses: who
and also who -q and also
who -b
The plain command just lists the names of users currently on
the server. Using the -q option allows you to quickly view just
the total number of users on the system. Using the -b option
reminds you how long it has been since you rebooted that stable
Linux server! One of my servers had a -b of almost three years! Yes, that's why we at reallylinux.com call it really Linux!
