A Final Warning
Aliases are very useful little things, but I hope that after this introduction, you find functions at least as interesting (and probably even more useful). A final caveat to both aliases and functions is that you should never replace a standard command with an alias or a function. It's too easy to really hurt yourself by trying to execute your alias when it doesn't exist. Imagine the difference between doing this:
$ alias rm='rm -i'
$ cd ~/scratch
$ rm * # here the rm alias catches you and interactively
# deletes the contents of your current directory
and then later in the same session doing this:
$ su - # cd /tmp # rm # here the rm alias no longer exists, and you whack # a bunch of stuff out of /tmp
Happy hacking!
