git bisect for lazy people

This walks the git history down from the current commit to the older commits.

Copy and adapt for your needs.

#!/bin/bash

BRANCH=your_branch

set -euxo pipefail
log_report() {
    echo "Error on line $1"
}
trap 'log_report $LINENO' ERR


git switch $BRANCH
git log --oneline | cut -d' ' -f1 | while read hash;
    do
    echo
    echo    $hash;
    git switch -d $hash
    DO_SOMETHING
    if YOUR_COMMAND; then
        echo "this is good (the commit above this introduced the bug): $hash"
        break
    fi
    git restore .
    sleep 1
done
git switch $BRANCH

You need to adapt these parts:

• BRANCH
• DO_SOMETHING
• YOUR_COMMAND: Should return 0 if everything is fine.
• remove "sleep 1", if you need to walk back a lot of commits.
