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
