What's in your .bash_aliases file?

[fancypiper]

I am looking for some more neat tricks you can use with a .bash_aliases file.

Here is my user .bash_aliases file. Post yours. :popcorn:

Among other things, this vipath function (http://ubuntuforums.org/showthread.php?p=8441063#post8441063). I don't use it much now, but it can be useful.

The two most useful for me:



# perform 'ls' after 'cd' if successful.
cdls() {
builtin cd "$*"
RESULT=$?
if [ "$RESULT" -eq 0 ]; then
ls
fi
}

alias cd='cdls'

# search for a string recursively in any C source files

I've switched to zsh this week, has far better aliases (you can use variables in them too, and they get autocompletion for their aliased object). But here is some stuff I use:

Most of these are functions, rather than aliases. The first four of these shell directory ops were first "borrowed" from a csh profile from Back In The Day when all there was was Bourne shell and C shell. When Korn shell came out, they were "ported" and expanded-on. I've been improving and expanding them ever since.

I'm a 'nix dinosaur. Been using some form or another of 'nix since before there was X :). So I still spend a lot of my time in the shell. Almost like one colleague of mine:


Me: So why do you use X, anyway, if you spend all your time in sh?
Him: How else to organize my xterms? :)
So, for those of you who spend a lot of time in ksh or bash, you might find these handy:


# directory operations: pushd, popd, flipd, and swapd as per csh
# Change to new dir, pushing current onto stack
function pushd {
export DS="$PWD:$DS"
if [ -n "$1" ]; then cd "$1"; else cd; fi || export DS="${DS#*:}"
}
# pop top dir off stack and cd to it
function popd {
if [ "$DS" ]
then
cd "${DS%%:*}"
export DS="${DS#*:}"
else
echo "$0: empty directory stack" >&2
fi
}
# flip back-and-forth between current dir and top of stack (like "cd -")
function flipd {
if [ "$DS" ]
then
cd "${DS%%:*}"
export DS="$OLDPWD:${DS#*:}"
else
echo "$0: empty directory stack" >&2
fi
}
# swap top two dir stack entries
function swapd {
typeset DSr="${DS#*:}"
if [ "$DSr" ]
then
export DS="${DSr%%:*}:${DS%%:*}:${DSr#*:}"
else
echo "$0: less than two on directory stack" >&2
fi
}
# rotate thru directory stack (from bottom to top)
function rotd {
if [ "$DS" ]
then
typeset DSr="${DS%:*:}"
[ "${DSr}" = "${DS}" ] || export DS="${DS##${DSr}:}$DSr:"
flipd
else
echo "$0: directory stack is empty" >&2
fi
}
# Print directory stack
function printd {
( IFS=:; for each in $DS; do echo $each; done; )
}
# Edit directory stack
function editd {
export EDITDNO=$((${EDITDNO:=0} + 1))
typeset FiLe=/tmp/`basename -- $0`$$.${EDITDNO}
printd >${FiLe}
${EDITOR} ${FiLe}
DS=`while read ea; do echo -n "$ea:"; done <${FiLe}`
rm -f ${FiLe}
}
alias lastd="cd $(cat ~/.lastdir)" # chng to last dir at 'bye'
# Save current dir for lastd on exit if not $HOME
alias saved='[ ${PWD} != ${HOME} ] && pwd >~/.lastdir; [ -n "${DS}" ] && echo "${DS}" >~/.dirstak'
Standard Disclaimer: No warranty for any particular use, express or implied. Use at your own risk!

(Edit): I realize that pushd() and popd() are bash builtins, but I over-ride them with my functions so they're all using the same directory stack.

Oh yeah, you'll also want this:


# get dir stack back on login
[ -s ${HOME}/.dirstak ] && export DS=`cat ${HOME}/.dirstak`
