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:
# down somesubdir## Find a directory below this that matches the word provided# (locate-based) function down() { dir="" if [ -z "$1" ]; then dir=. fi dir=$(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 shapefunction cdd() { dir="" if [ -z "$1" ]; then dir=. fi dir=$(locate -n 1 -r $1$) cd "$dir";}Other variations that I tried:
# Not breadth-first, so less fun sometimes function down2() { dir="" if [ -z "$1" ]; then dir=. fi dir=$(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 [ $dirlist ] do # check the head of the list to see if it matches needle val=${dirlist[0]} found=`expr match "$val" ".*$1.*"` if [ $found -gt 0 ]; then # change dirs, we found the first match cd "$val"; break # done else # 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 fi done }
