for d in $MYDIR/*
do
   echo $d
done

This kind of file and directory processing can be very consise in a
shell (bash, ksh or zsh or name it; this type of constructs can be
used on the command line too)
For short commands it can't be beaten by higher level scripts. But
the point where it is smarter to use perl or ruby is quickly
reached....
