#### Get list of objects by size ####

# work over each commit and append all files in tree to $tempFile
tempFile=$(mktemp)
IFS=$'\n'
for commitSHA1 in $(git rev-list --all); do
  git ls-tree -r --long "$commitSHA1" >>"$tempFile"
done

# sort files by SHA1, de-dupe list and finally re-sort by filesize
sort --key 3 "$tempFile" | \
  uniq | \
  sort --key 4 --numeric-sort --reverse

# remove temp file
rm "$tempFile"

#### Move uncommitted changes on master to another branch ####
# From: https://stackoverflow.com/questions/14506910/git-move-changes-off-of-master-branch

# How to move the changes into a new branch new-working-branch and then discard working-branch
git checkout -b new-working-branch
git add …
git commit -m "mycommit" 
#As you didn’t commit anything to master yet, you don’t need to change anything on master. You can now discard your working-branch if you feel like it.

# How to move the changes over to working-branch

## Works in any case:
git checkout -b temp-branch 
git add …
git commit -m "mycommit" 
git rebase --onto working-branch master
git checkout working-branch
git reset --hard temp-branch
git branch -d temp-branch

## If your changes don’t conflict with any changes that are on master, but not in working-branch, this can be done a lot simpler:

git stash
git checkout working-branch
git stash pop


#### Count number of commit in branch_A not in branch_B ####

git rev-list --count branch_A ^branch_B
