Some handy bash commands

On Linux shells, I always feel pretty crummy about getting around quickly via cd. So, in the spirit of Daniel's up command, here's a few other quick-directory commands to add to your .bashrc:

# up somesubdir
# Find a directory below this that matches the word provided
# (locate-based)
function down() {
if [ -z "$1" ]; then
dir=$(locate -n 1 -r $PWD.*/$1$)
cd "$dir";

# cdd someglobaldir
# quickly change to a directory anywhere that matches the word you typed.
# best if your locatedb is in good shape
function cdd() {
if [ -z "$1" ]; then
dir=$(locate -n 1 -r $1$)
cd "$dir";

Other variations that I tried:

# Not breadth-first, so less fun sometimes
function down2()
if [ -z "$1" ]; then
dir=$(find . -type d -iname $1 | head -n 1)
cd "$dir";


# Breadth-first, but really slow
function down3()
# create a list of all directories in the current folder
dirlist=( $(find . -maxdepth 1 -type d) )
dirlist=( ${dirlist[@]:1} ) # exclude .

# loop through the list
while [ $dirlist ]
# check the head of the list to see if it matches needle
found=`expr match "$val" ".*$1.*"`
if [ $found -gt 0 ]; then
# change dirs, we found the first match
cd "$val";
break # done
# not found!
# scan that new directory for subdirs
appendlist=( $(find $val -maxdepth 1 -type d) )
appendlist=( ${appendlist[@]:1} ) # exclude .
# add those subdirs to the tail of the dirlist
dirlist=( ${dirlist[@]:1} ${appendlist[@]} )

# rinse, repeat

Zsh has glob features that do something like what you've done.
