Shortcuts to recurrent Git commands

Sync remote fork

git fetch public
git checkout master
git merge public/master

List branch remote

git branch -vv

Checkout from a remote branch

git co -b <local name> upstream/master

Push to a remote upstream branch

git push <remote> <local branch>:<remote branch>

eg:

git push upstream foo:master

Pull options

git config pull.rebase false # merge (the default strategy) git config pull.rebase true # rebase git config pull.ff only # fast-forward only

Subtree

The tests directory is a Git subtree created with the following commands:

git remote add tests git@github.com:nextflow-io/tests.git
git subtree add --squash --prefix=tests/ tests integration

To pull changes from the tests repo use this command:

git subtree pull --squash --prefix=tests/ tests integration

To push changes to the tests repo use this command:

git subtree push --prefix=tests/ tests integration

Stash shortcuts

git stash list
git stash pop
git stash pop stash@{1}
git showtool stash@{0}
git stash drop
git stash drop stash@{1}
git stash clear
git diff stash
git diff stash@{1} [other]

Find a commit in any branch introducing a change

git log --source --all -S <whatever>

Reset last merge pushed

git reset --hard HEAD@{1}

GPG keys

To sign Git commits with a GPG key on Mac use GPG Suite, import your key, then:

git config --global gpg.program /usr/local/MacGPG2/bin/gpg2
git config --global user.signingkey <your key> 
git config --global commit.gpgsign true 
git config --global format.signoff true ## TO AVOID TO SPECIFY -S option each time

Pull master while in a another branch

git fetch origin master:master

Alternative to `git pull`

Use git fetch && git rebase

Code stats

Lines added/removed/changed (read more)

git log --shortstat --since "1 year ago" --until "1 week ago" | grep "files changed" | awk '{files+=$1; inserted+=$4; deleted+=$6} END {print "files changed", files, "lines inserted:", inserted, "lines deleted:", deleted}'

Commits in a period

git rev-list --count HEAD --since=“May 18 2020” --before=“May 18 2021" --all

Diff all files matching a glob pattern

git diff <tag1> <tag2> -- '<some glob>'

For example:

git difftool v21.01.0-edge v21.02.0-edge -- '**/MANIFEST.MF'

Find text across any branch

git grep "string/regexp" $(git rev-list --all)

Find all tags containing a commit

git tag --contains <commit id>

Find last 6 months committers

git ll --since="last 6 month" | sed 's/.*<\(.*\)>/\1/g' | sort | uniq

Find when a tag was created

git for-each-ref --format="%(refname:short) | %(creatordate)" "refs/tags/*"

Count lines of code in a period

git log --shortstat --author "paolo.ditommaso" --since "1 years ago"  | grep "files changed" | awk '{files+=$1; inserted+=$4; deleted+=$6} END {print "files changed", files, "lines inserted:", inserted, "lines deleted:", deleted}'

Delete all tag and releases with a given pattern

for x in `git tag | grep -- <PATTERN>`; do gh release delete -y $x; git push origin :$x; git tag -d $x;  done

Push remote forks

gh pr checkout 5042
git commit -am "my changes"
git push

This depends on the check box being ticked by the end user to allow this (it is by default) and it not coming from an organisation's fork.
