My favourite bash aliases currently are
alias hist='history|egrep'
and
alias ös='ls'
The second one for the reason that 'ö' sits next to 'l' on my Swedish keyboard, and when I intended to type 'ls' I type 'ös' more often than not. The one I use the most, however, is
alias more='m' (I also have the classic more='mroe' and more='moer' to catch some frequent typos).The first one,
hist, makes it possible to use regular expressions to search the history of earlier shell commands. This is useful when you cannot remember some tricky command line sequence, or are too lazy to type some long command that you know you issued the other day.For instance
hist 'java|ruby'
will print any previous command (in bash's history) containing any of the two strings.
(Well, I think you can accomplish the same thing using the original
history command, but to paraphrase Morrissey, now my head is full, and my brain doesn't have room for more cryptic command line arguments.)You can put your bash aliases in
~/.bashrc(Thanks to Chris for spotting a (now corrected) mistake in the first example. See the comment below.)

Ctrl-r seems useful for searching the Bash history!
