aliases can be very nice, yes. I also have the ls alias Mike suggests, but
I have a bunch of strange and bizarre others:

----------------------------------------------------------------------
alias la='ls -al'
alias ll='ls -l'
alias l='ls'		# Saves a whole 1 character! Woohoo!

alias c='clear'
alias j='jobs'
alias m='mutt -y'		# shows status of all mail folders
alias mm='mutt -f ~/Mail/mbox'	# reads just personal mail folder
alias s='ls -lt ~/Mail | head -15'	# shows (quickly) the most recently
					# modified mail folders
alias h='history 1'

# Of course... :)
alias vi='vim'

# Oooh, and a bunch of very useful CVS aliases...
# Note these should not be used without an appropriate ~/.cvsrc
alias cc='cvs commit'
alias cl='cvs log'
alias cs='cvs status'
alias cf='cvs status | grep File:'	# great for quickly showing
					# modified files
alias cx='cvs diff'
alias cu='cvs update'
----------------------------------------------------------------------

Aliases don't always have to be sophisticated to be useful. All the
one-character aliases above I use very frequently, and it can be disturbing
sometimes when I use a foreign system and realise "oh bugger, that's right,
c has to be _aliased_ to clear first..." :)

Not being particularly fluent in shell programs in general - how does the
second one work exactly? Doesn't '$*' represent all arguments/parameters to
the function and '$1' represent the first one? Oh, I get it - grepping out
the grep process, very sneaky.

Well I tend towards aliases rather than functions, and you've already seen
all my best ones up above *shuffles feet* Okay, I know they're not _that_
good, but they're useful.... :)

Om *mumbles meditatively*.
