Blog post about git pruning history and finding large objects in your
repo: http://stubbisms.wordpress.com/2009/07/10/git-script-to-show-largest-pack-objects-and-trim-your-waist-line/
This is a script I put together after migrating the Spring Modules
project from CVS, using git-cvsimport (which I also had to patch, to
get to work on OS X / MacPorts). I wrote it because I wanted to get
rid of all the large jar files, and documentation etc, that had been
put into source control. However, if _large files_ are deleted in the
latest revision, then they can be hard to track down.
#!/bin/bash
#set -x
# Shows you the largest objects in your repo's pack file.
# Written for osx.

# @author Antony Stubbs
# set the internal field spereator to line break, so that we can
iterate easily over the verify-pack output
IFS=$'\n';
# list all objects including their size, sort by size, take top 10
objects=`git verify-pack -v .git/objects/pack/pack-*.idx | grep -v
chain | sort -k3nr | head`
echo "All sizes are in kB's. The pack column is the size of the
object, compressed, inside the pack file."
output="size,pack,SHA,location"
for y in $objects
do
# extract the size in bytes
size=$((`echo $y | cut -f 5 -d ' '`/1024))
# extract the compressed size in bytes
compressedSize=$((`echo $y | cut -f 6 -d ' '`/1024))
# extract the SHA
sha=`echo $y | cut -f 1 -d ' '`
# find the objects location in the repository tree
other=`git rev-list --all --objects | grep $sha`
#lineBreak=`echo -e "\n"`
output="${output}\n${size},${compressedSize},${other}"
done
echo -e $output | column -t -s ', '
