Use these scripts in a cron job to automatically commit daily to a git repo and create a weekly Git branch.

Commit Daily

The following script will commit, pull and push changes when needed. It is used daily, or if wanted hourly.

filename: commit-daily.sh

#!/bin/sh
set -e

echo "------------------------------------------------------------------------"

PREFIX="[commit-daily]"

echo $PREFIX $1
cd $1

[ "$(ps -o comm= $PPID)" = "branch-weekly.s" ] && PREFIX="[branch-weekly]"

git fetch --all

if [ "$(git status --porcelain)" ]; then
  echo $PREFIX commit open changes
  git add -A
  git commit -am $(date +%Y%m%d%H%M)
else
  echo $PREFIX no open changes
fi

if [ $(git rev-list @..@{u} --count) -eq 0 ]; then
  echo $PREFIX remote has NO new commits
else
  echo $PREFIX rebase on new commits in remote
  git pull --rebase
fi


if [ $(git rev-list @{u}..@ --count) -eq 0 ]; then
  echo $PREFIX local has NO new commits
else
  echo $PREFIX push new commits to remote
  git push
fi

Use the following line in cron to call the script. This will run it each day at 1 in the morning

0 1 * * * /home/<user>/.local/bin/commit-daily.sh <directory>

Branch Weekly

The following script assumes the local repo already has two branches, a weekly branch and master. It also assumes the commit-daily.sh daily script (above) is available.

filename: branch-weekly.sh

#!/bin/sh

set -e

PREFIX="[branch-weekly]"

echo "------------------------------------------------------------------------"
echo $PREFIX $1
cd $1

current_branch=$(git rev-parse --abbrev-ref HEAD)
new_branch=$(date +y%Yw%W)

if [ "$current_branch" = "$new_branch" ]; then
  echo $PREFIX nothing to do
  exit 0
fi

echo $PREFIX calling commit-daily
/home/akkerman/.local/bin/commit-daily.sh $1

echo $PREFIX merge current branch to main and delete
git switch main
git merge $current_branch --squash
git commit -am $current_branch
git branch -D $current_branch

echo $PREFIX create new branch
git switch -c $new_branch

echo $PREFIX update origin
git push origin +main:main
git push --delete origin $current_branch
git push --set-upstream origin +$new_branch:$new_branch

Use the following line in cron to call the script. This will run it each monday at 1 in the morning

0 1 * * 1 /home/<user>/.local/bin/branch-weekly.sh <directory>
