retry

Continually run any command until it succeeds (or fails!)

Examples

1. Retry a command up to 5 times until it's exit code is 0, sleeping longer between each run

    $ retry echo 'test'
   

2. Run a command indefinitely until it's exit code is non-0, sleeping 2 seconds between each run:

    $ retry -n 0 -s 2 -x ls /dev/ttyUSB1
   

   or, if you prefer GNU style long options:

    $ retry --max-tries=0 --sleep=2 --retry-on-success ls /dev/ttyUSB1
