xargs/grep/expr syntax error

I need to execute a command which returns an integer and compare that result to the result of another integer-returning command and get back 0 or 1 if the integers match or not. Here's what I have:
/home/me -T B | grep -c 11 | xargs expr -I{} != /home/me -TC | grep 20081008 | grep -c 11. I'm getting a syntax error. Is what I'm trying to do possible? If so, what's the issue with my syntax?

Thanks in advance,

#!/bin/bash
res1=`/my/command1`

if [ "$res1" = "$res2" ]
then

You can do something like if [ `command1` -eq `command2` ]; then echo match; fi
but you cant do command1|command2 and then compare their return status.

to clarify further ... `` would capture the output ... If you mean values returned to shell, you would need $? to get return status of last command

command1
r1=$?
command2
r2=$?
if [ $r1 -eq $r2 ]
then
   echo match
else
   echo failed
fi

A one liner to compare two commands is
[ `cmd1` -eq `cmd2` ] && echo match

If you use the $() construct instead of backticks, you get the advantage that you can nest $(). Also I think it's easier to read, but that's only a personal opinion

[ $(/home/me -T B | grep -c 11 | xargs expr -I{}) != $(/home/me -TC | grep 20081008 | grep -c 11) ] && echo 0 || echo 1

Not sure about "expr -I{}" though, what does that do?
