Koha/debian/scripts/koha-restart-zebra
Tomas Cohen Arazi cee6909c8a Bug 10149 - koha-restart-zebra error handling (rewording)
koha-restart-zebra now
- Checks the instance exists.
- Checks the instance is enabled.
- Checks if the zebra daemon is already running.

Regards
To+

Edit:
- changed some wording problems.
- fixed an error in parameter validation
