How incredibly useful. I note with irony:
/sbin ...this directory holds commands... which are usually not
executed by normal users
I estimate that 50% of the commands I must issue from the console
(because they do not have GUI equivalents) are in this directory. That
is why your previous $PATH tip was so useful to me!

Some more commands I have found useful, especially on a laptop:
$ /sbin/snooze -- puts a Macintosh-based desktop or laptop computer to
sleep
$ uptime -- time since last reboot
$ top -- running processes (type "h" while top is running to get a list
of additional options, type "q" to quit)
$ df -h -- amount of drivespace used on mounted volumes (unlike some
commands, the "-h" means "human-readable," not "help")
$ kdf & (or "/usr/bin/kdf" &) -- KDiskFree, a GUI to mount and unmount
drive partitions; the "&" at the end tells the commandline to return to
the user rather than wait for the program (kdf, in this case) to be
terminated
$ whereis progname -- where "progname" is the name of some incredibly
useful command for which you do not remember the correct path
$ which progname -- nearly identical to "whereis"; in fact, I don't
know the differences, if any
$ who -- how many and which users are logged in (note that even if you
are the only user, you will see your name for every instance you are
logged in, including X windows and commandline)
Finally, I have made lots of use of a "Desktop button" that can be
included in your kicker panel (that taskbar-like thingy at the bottow
or top of your screen. Right-click on the panel, select Panel Menu, and
navigate to "Add" and "Special button." There are a few useful gadgets
in there, including the "Show Desktop" button. If you have many windows
open from many applications, clicking on "Show Desktop" will minimize
all the applications, giving you access to your Desktop. Quite useful,
and Terra Soft should include it in the default install.
Best wishes,
Clint
