#### Examples

View the list of big files in the git repo and the git repo history (from the
sourcecode repo of this website):



   remy at sparcstation-20 in ~/repo/raymiiorg (master)
   $ ~/bin/git-clean.sh df
   All sizes are in kB's. The pack column is the size of the object, compressed, inside the pack file.

(note the backslash in the filename):

#### The script



   #!/bin/bash
   # Script to remove files from the git history.
   # Execute this script in the git root directory
   # For a size report: ./gitsize.sh df
   # To remove the big files:
   # use like: ./gitsize.sh rm $bigfilename
   # Example: ./gitsize.sh rm includes/ubuntu-12.04.iso
   # It will then search your git repo and remove all of it.
