   1 #!/bin/sh

   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 sha1> <remote ref> <remote sha1>
  18 #
  19 # This sample shows how to prevent push of commits where the log message starts
  20 # with "WIP" (work in progress).
