#!/bin/sh # An example hook script to verify what is about to be pushed.  Called by "git# push" after it has checked the remote status, but before anything has been# pushed.  If this script exits with a non-zero status nothing will be pushed.## This hook is called with the following parameters:## $1 -- Name of the remote to which the push is being done# $2 -- URL to which the push is being done## If pushing without using a named remote those arguments will be equal.## Information about the commits which are being pushed is supplied as lines to# the standard input in the form:##   <local ref> <local sha1> <remote ref> <remote sha1>## This sample shows how to prevent push of commits where the log message starts# with "WIP" (work in progress). remote="$1"url="$2" z40=0000000000000000000000000000000000000000 while read local_ref local_sha remote_ref remote_shado	if [ "$local_sha" = $z40 ]	then		# Handle delete		:	else		if [ "$remote_sha" = $z40 ]		then			# New branch, examine all commits			range="$local_sha"		else			# Update to existing branch, examine new commits			range="$remote_sha..$local_sha"		fi 		# Check for WIP commit		commit=`git rev-list -n 1 --grep '^WIP' "$range"`		if [ -n "$commit" ]		then			echo >&2 "Found WIP commit in $local_ref, not pushing"			exit 1		fi	fidone exit 0
