| 3 | # An example hook script to verify what is about to be pushed. Called by "git |
| 4 | # push" after it has checked the remote status, but before anything has been |
| 5 | # pushed. If this script exits with a non-zero status nothing will be pushed. |
| 6 | # |
| 7 | # This hook is called with the following parameters: |
| 8 | # |
| 9 | # $1 -- Name of the remote to which the push is being done |
| 10 | # $2 -- URL to which the push is being done |
| 11 | # |
| 12 | # If pushing without using a named remote those arguments will be equal. |
| 13 | # |
| 14 | # Information about the commits which are being pushed is supplied as lines to |
| 15 | # the standard input in the form: |
| 16 | # |
| 17 | # <local ref> <local oid> <remote ref> <remote oid> |
| 18 | # |
| 19 | # This sample shows how to prevent push of commits where the log message starts |
| 20 | # with "WIP" (work in progress). |
