This question comes up every now and then - how to convert from normal
to bare, or vice versa.

This is just a start to a basic script to go one way. Needs more tests
etc, but it's enough to get newbies (like me) off to a reasonable
start.

PLEASE CC me, as I am not subscribed.

Thanks,

I needed this quite a bit in the last few days, basic script but
serves my need. I think it would be useful for other beginners if in
$git/contrib/ source dir.

Just a start to a basic script. Needs more tests etc, but it's enough
to get newbies (like me) off to a reasonable start. Handles multiple
input dirs.

PLEASE CC me, as I am not subscribed.

The user would appreciate if you check that there are no uncommited
changes and no untracked files (at least no untracked and not ignored
files) before running this.

Also, it's "$repo", not just $repo, or you'll get surprising behavior if
$repo contain spaces.

The safe way would actually be stg like:

  rm -fr -- "$repo"

in case $repo starts with a dash.

Thanks.

In my later email, I changed it to mv - should have highlighted there
was a change. I got bitten, on a small repo thankfully, where a perms
or ownership problem caused the whole repo to disappear. So mv it is
:)

BTW, I've subscribed for a little while now...

Thanks again

Do you really need bash for that script or will it do with sh? I think
sh is preferred.

Also a mv instead of a rm will require a lot of disc space if you have a
big repository.

I do not think you need (nor used) any bash-ism in this script.
Saying "#!/bin/sh" here is cleaner.

	for i
        do

You do not have to say 'in "$@"'; it is implied.

Forgot to dq?

Forgot to dq?  i.e.

	mv "$repo/.git" "$tmp_repo"

The same for all the variable references in the remainder of the
script.

More importantly, "mv" would fail if $repo is given as a full
pathname elsewhere in the filesystem that is different from your
current directory where you create $tmp_repo.

You do not need to ask to be CC'ed. Any mailing list properly configued would
not munge the Reply-To header, so anybody replying to this mail would reply to
you.

Git is a properly configured mailing list, just like all the mailing list in
vger.kernel.org.

Cheers.
