If you ever want to run the same command in each sub-directory of a directory consider the following example.
Replace the value for COMMAND with your own command.
$ COMMAND=pwd
$ for d in `find . -maxdepth 1 -type d`; do pushd > /dev/null $d; $COMMAND; popd > /dev/null; done
Or setup your own command by putting the following in your .bashrc file.
function run-command-in-subs {
for d in `find . -maxdepth 1 -type d`;
do
pushd > /dev/null $d;
$1;
popd > /dev/null;
done
}
