Here's a script that I use:

vvv
#!/bin/sh

# forall

if [ 1 = `expr 2 \> $#` ]
then
echo Usage: $0 dir cmd [optargs]
exit 1
fi
dir="$1"
shift
find "$dir" -type f -printf "\"%p\" " | xargs "$@"
^^^

Then to use it...

Make it available in your PATH. The traditional way to do that is to
put the script in /usr/local/bin.

Make sure it has useful permissions (do "chmod 755 forall").

Then run it like this:

forall /etc/rc.d grep cups

Or

cd /etc/rc.d
forall . grep cups

The forall script used this way will search all subdirectories too.
This can be very useful when you are looking thru files for something,
and you don't know where it is.

Combine it with less and you have an even more useful search tool:

forall <dir> grep <string> | less

By the way, forall is a part of a SourceForge project which you can
visit at:
