In the issue reported in the previous commit, the garbage output of the --funcs command was being ignored by the test when it could have been caught. The script first makes use of --funcs option with the perf probe command to check if the function "foo" exists in the testfile before adding a probe to it in the next command. The output of probe...--funcs command is redirected to stdout, therefore, add '| grep "foo"' to validate the result.
