Little bash script that re-runs a command until it exits with code 0, i.e. runs successfully. I get impatient when SSH'ing to new servers...

retry.sh

#!/bin/bash

# Examples: 
#
# When's the damn thing online?
#
#   $ retry.sh ssh [email protected]
#
# When's internet back?
#
#   $ retry.sh ping -c 1 google.com
#

ret=1
while [[ $ret -ne 0 ]]; do
    $@
    ret=$?
    if [[ $ret -ne 0 ]]; then
        sleep 1
    fi
done
