why not use:

if [ -d /var/cache/fonts ]; then
   pushd /var/cache/fonts
   rm -rf source tfm pk
   popd
   rmdir /var/cache/fonts 2>/dev/null || true
fi

pushd:
Adds a directory to the top of the directory stack, or rotates the
stack, making the new top of the stack the current working directory.

popd: 
Removes entries from the directory stack.  With no arguments,
removes the top directory from the stack, and cd's to the new top
directory.

pushd/popd are builtins of bash.

Bye
