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.
