I'm having trouble getting post-recieve and post-commit hooks to work correctly with msysgit (Windows 7 Pro/32 and Ultimate/64). For post-commit hook I get the above error if I commit from either git-bash or the console, but it works fine if I commit through git-gui. For a post-recieve hook, all three give the same error.
I'm thinking this is some sort of permission or path error, but don't really have any clue where to start here.
Add the SHEBANG to the first line of hook, like so:
#!/bin/sh
echo "executing post-commit"
exit 0
This had me stumped for a while as well and I saw that adding the shebang fixed it. In SVN world, while in *nix we have a "pre-commit" script and in Windows we had "pre-commit.bat" and SVN automatically picked up the bat file in Windows. Git doesn't seem to pick up a pre-commit.bat ( or any hook ) and adding the shebang to the hook file worked.
