FYI, execute_process supports multiple COMMAND options and will construct
a pipeline threading each command's stdout to the next command's stdin.
Therefore you should be able to do piping like the above if you know a
grep is available.  Otherwise you could also consider using OUTPUT_FILE
to put the output in a temporary file and then use file(STRINGS) to load
a subset of it into memory.
