Refresh local git repositories

I keep all my software that is under version control below a few directories only. E.g. OpenSource projects I cloned to learn from them live below ~/OpenSource. Keeping up with updates requires to pull them all.

Pulling the main branch

My little helper does:

• change into each first level sub directory
• check if it is under version control
• capture the current branch
• switch to main or master branch, depending on which one is there
• capture the name of the tracked remote
• fetch all remotes
• pull the tracked remote
• switch back to the branch it was in

The script does not check if the current branch is dirty (preventing checkout) or pushing back changes. Enjoy

#!/bin/bash
# Pull all repos below the current working directory

do_the_sync() {
  for f in *; do
      if [ -d $f -a ! -h $f ]; then
         cd -- "$f";
         if [ -d ".git" ]; then
            curBranch=$(git branch --show-current)
            mainBranch=nn
            echo "Working on $f";
            if [ "`git branch --list main`" ]; then
              mainBranch=main
            else
              mainBranch=master
            fi
            remoteBranch=$(git rev-parse --abbrev-ref ${mainBranch}@{upstream})
            IFS='/' read -r remoteSrv string <<< "$remoteBranch"
            echo "working on $mainBranch tracking $remoteSrv"
            git fetch --all
            git pull $remoteSrv
            git checkout $curBranch
         fi
         cd ..
      fi;
  done;
};

do_the_sync
echo "DONE!"

As usual YMMV
