Ubuntu – Git commit message problem

I normally just use git gui. It shows the list staged and unstaged changed files, and shows their diffs, and lets you selectively stage hunks, add a log message, and commit. Even has a nice knob to amend the last commit instead.

Here is a perl script to determine the size of each Git commit:

The source is here, I have added one modification:

#!/usr/bin/perl
foreach my $rev (`git rev-list --all --pretty=oneline`) {
  my $tot = 0;
  ($sha = $rev) =~ s/\s.*$//;
  foreach my $blob (`git diff-tree -r -c -M -C --no-commit-id $sha`) {
    $blob = (split /\s/, $blob)[3];
    next if $blob == "0000000000000000000000000000000000000000"; # Deleted
    my $size = `echo $blob | git cat-file --batch-check`;
    $size = (split /\s/, $size)[2];
    $tot += int($size);
  }
  my $revn = substr($rev, 0, 40);
#  if ($tot > 1000000) {
    print "$tot $revn " . `git show --pretty="format:" --name-only $revn | wc -l`  ;
#  }
}

Start the script in your git repository.

<path_to_script>/commit-size | awk '/\s80973c0/ {print $1 " bytes"}'  80973c0

My example:

± commit-size | awk '/\se920f35/ {print $1 " bytes"}'  
546 bytes
