Sure. Since you know unix well enough to know about cmp, here's a 
three-line shell script to do that. Give it two command-line arguments 
and it gives you the answer.

#!/bin/sh
fstat() { ( cd `dirname $*` ; p4 fstat `basename $*` | grep -v clientFile ) }
[ "`fstat $1`" = "`fstat $2`" ] && echo Same file || echo Different file
