Bash script to perform an action on each subdirectory in a directory

Question

Assuming I have a directory structure like

Dir1/
  SubDir1/
  SubDir2/
  SubDir3/

I'd like to be able to pass 'Dir1' to a bash script and then perform an action on all of it's subdirectories (SubDir1, SubDir2, SubDir3).

Thanks for your help!

Answer 1

Given it sounds like you're going to be running tar, the best way is probably:

basedir=$1
for dir in "$basedir"/*; do
    if test -d "$dir"; then
        tar -cvf "$dir".tar "$dir"
        rm -r "$dir"
    fi
done

If you wanted to use find, you should add -maxdepth 1, to avoid creating extra tar files.

basedir=$1
for dir in $(find "$basedir" -mindepth 1 -maxdepth 1 -type d); do
    tar -cvf "$dir.tar" "$dir"
    rm -r "$dir"
done

Also note that in tar -cvf, the name of the output file comes first (right after the f).

Answer 2

find Dir1 -mindepth 1 -type d -exec dosomethinghere {} \;
