I am working on a script that needs to perform an action in every sub-directory of a specific folder. What is the most efficient way to write that? for D in `find . -type d` do //Do whatever you need with D done kanaka A version that avoids creating a sub-process: for D in *; do if [ -d "${D}" ]; then echo "${D}" # your processing here fi done Or, if your action is a single command, this is more concise: for D in *; do [ -d "${D}" ] && my_command; done Or an even more concise version ( thanks @enzotib ). Note that in this version each value of D will have a trailing slash: for D in */; do my
