Un naufragio personal

Showing an intermixed short log of a bunch of git repositories

I store all my git repositories under the same directory, unsurprisingly called ~/git. I needed a way to have a quick list of what I have done in all of them in a given time, so I wrote a script named (probably incorrectly) my-git-metachangelog.sh. This script iterates all subdirectories, finds all that are git repositories, takes a shortlog for all of them, and sorts by date. The fields shown are: date, time, project and the first line of the commit message.

By default, shows the short log for the last 6 months. It accepts an optional unique argument with the number of months to summarize.

This is an example of its output:

 2008-12-11 18:25:29 gruta: Changed all POD docum. in templates to head2.
 2008-12-11 17:04:37 gruta: New templates 'main_top' and 'main_bottom'.
 2008-12-11 10:57:19 grutatxt: The option 'no-pure-verbatim' has been docum.

 2008-12-07 08:42:38 mp-5.x: Version 5.1.1 RELEASED.
 ...

And the script:

 #!/bin/sh
 # my-git-metachangelog.sh
 # Angel Ortega <angel@triptico.com> - public domain
 
 MONTHS=$1
 
 [ -z "$MONTHS" ] && MONTHS=6
 
 for r in *
 	do ([ -d $r ] && cd $r &&
 		git rev-parse HEAD > /dev/null 2>&1 &&
 		git log --no-merges \
 		--since="$MONTHS months ago" \
 		--pretty="format:%ai $r: %s%n")
 	done | \
 grep -v '^$' | sed -e 's/+[0-9][0-9][0-9][0-9] //' | \
 sort -r | less

2010-12-08 update: Fixed to also work on bare repositories.
