I didnt mean to cause offense. Sorry if I did. There is a command in linux/unix called man. If you want to know about a command, type it in, followed by the command you want knowledge of.

For example, if you want to know about the uptime command, you type in:

Code:
man uptime
it gives:

Code:
NAME
       uptime - Tell how long the system has been running.

SYNOPSIS
       uptime
       uptime [-V]

DESCRIPTION
       uptime gives a one line display of the following information.  The cur-
       rent time, how long the system has been running,  how  many  users  are
       currently  logged  on,  and the system load averages for the past 1, 5,
       and 15 minutes.

<snip>

SEE ALSO
       ps(1), top(1), utmp(5), w(1)
other commands of interest are: iostat, vmstat, sar

HTH.
