Does a File Contain Some Text?

The "find" command can return a return code of zero if a file contains some text. 

echo SanityCheck1 > "%OutputFile%" 2>&1
SomeProcess.exe > "%OutputFile%" 2>&1
type "%OutputFile%"
find "failed" "%OutputFile%"
if errorlevel 1 goto FAILED_FOUND
echo *** Command Worked ***

Of course "FindStr.exe" and many other tools (like "grep.exe") would allow you to use regular expressions to find more complicated types of matches.
