Check output of command before outputing and keep exit code
so i have scripts that are piped and then run through one of the following mechanisms:

Code:
cat myscript.sh | sh 

cat myscript.pl | perl

what i want to do is, after either of the above commands are run, if the output from the command contains a certain string, i want it to avoid printing anything. but IF the output does not contain the specified string, then it should proceed as normal and output the result of the script and also preserve the exit code.

so in essence, what im attempting to do can be best illustrated with this:

Code:
cat myscript.sh | sh ; EXITCODE=$? | awk '!/patternToSearchFor/ {print $0}' ; exit ${EXITCODE}

cat myscript.pl | perl ; EXITCODE=$? | awk '!/patternToSearchFor/ {print $0}' ; exit ${EXITCODE}

this code is faulty and i'm hoping someone can help me fix it.
