Shell – Count how many directories have at least one file with specific extension

filesshell

How can I know how many directories (in current directory) have at least 1 file with a .mp3 extension.

No need recursion — directory structure from current dir is for example:

1/blabla.mp3
2
3/something.mp3
4
5

The command should return that there are 2 dirs with mp3 file(s).

Best Answer

find . -type f -name "*.mp3" -exec dirname {} \; | uniq | wc -l

In zsh, you can use a recursive glob:

mkdir ~/epubs
mv -- **/*.epub ~/epubs/

In bash ≥4, run shopt -s globstar (you can put this in your ~/.bashrc) then the command above. In ksh, run set -o globstar first.

With only POSIX tools, run find:

find . -name '*.epub' -exec mv {} ~/epubs \;

for f in *.cut *.cut.bak
do
    [ -e "$f" ] || continue
    f="${f%%.bak}"
    f="${f%%.cut}"
    [ -e "$f".mpg ] || [ -e "$f".rec ] || rm -i -- "$f".cut "$f".cut.bak
done
