'''Getting Help with Linux Commands'''
With the Linux OS containing over '''2500''' commands and utilities, it is good for a Linux user or <br>Linux system administrator (sysadmin ) to learn about how to use commands “on-the-fly”.<br><br>
The '''man''' command can provide information on how to use a command<br>(i.e. '''command usage''', '''acceptable command arguments''', '''command options''', '''examples''').<br><br>
# Issue the following command: <span style="font-family:courier;color:blue;font-weight:bold">man man</span><br><br>You may notice that the online manual categories commands into sections or '''numbered volumes'''.<br><br>
