-Usage:
- $WAITFORIT_cmdname host:port [-s] [-t timeout] [-- command args]
- -h HOST | --host=HOST Host or IP under test
- -p PORT | --port=PORT TCP port under test
- Alternatively, you specify the host and port as host:port
- -s | --strict Only execute subcommand if the test succeeds
- -q | --quiet Don't output any status messages
- -t TIMEOUT | --timeout=TIMEOUT
- Timeout in seconds, zero for no timeout
- -- COMMAND ARGS Execute command with args after the test finishes
-USAGE
- exit 1
