Perform a task on a whole directory

Those commands will work on the current dir and the subdirs too.

Obtain the md5 hash of all files on a directory.
find. -print | xargs digest -a md5

Obtain the md5 hash of all files on a directory except for the dot (current dir)
find. -print | egrep -v '^\.$' | xargs digest -a md5

touch all files on a directory
find. -print | xargs touch

NOTE: find can use the parameter -type f instead of just -print for printing only files, and not directories.
