Re: Getting git to help my memory

I have a cron job that sends me a mail with the list of "unpushed" repositaries on my account every nights (it also runs "git fsck", "git gc", and writes some .keep files to prevent "git gc" from repacking large packs and be friendly with backups and unison).

It's not really cleaned up, and may well work just for me, but in case you're interested, the scripts are attached:

* git-gc-fsck.sh is the script itself

* git-foreach is a home-made git command to manage a set of unrelated
  repositories. Essentially, one can

  git foreach update   => run some "find" commands in your $HOME to find
                          repositories.

  git foreach do blah  => run command blah in each repository.

#! /bin/sh

diff=$(git-foreach update)

if [ "$diff" != "" ]; then

	echo "$diff"
	echo
    ) >> "$body"
    subject="$subject change"

        pwd
        echo "$graph" | sed "s/^/    /"
        echo

if [ "$unpushed" != "" ]; then
    (
	echo "Some Git repositories have unpushed content:"
	echo "$unpushed"
	echo
    ) >> "$body"
    subject="$subject unpushed"
fi

failed_fsck=$(git-foreach do git fsck 2>&1) fsck_status=$?

echo "$failed_fsck"

    git-foreach do git gc > /dev/null; then
    echo "git gc succeeded"
else
    echo "git gc failed, fsck succeeded. This is VERY strange ..."
    subject="GC $subject"
    status=1

BTW, if you really always want to push after commit, you can as well have a post-commit-hook that does the push for you. But you lose part of the power of Git by doing so (you can't rebase -i before pushing for example).
