Simple bash script for fetching and pulling all repos in the executed folder to the latest of the branch they are on

git_fetch_pull_all_subfolders.sh

#!/bin/bash

################
# Uncomment if you want the script to always use the scripts
# directory as the folder to look through
#REPOSITORIES="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"
REPOSITORIES=`pwd`

IFS=$'\n'

for REPO in `ls "$REPOSITORIES/"`
do
  if [ -d "$REPOSITORIES/$REPO" ]
  then
    echo "Updating $REPOSITORIES/$REPO at `date`"
    if [ -d "$REPOSITORIES/$REPO/.git" ]
    then
      cd "$REPOSITORIES/$REPO"
      git status
      echo "Fetching"
      git fetch
      echo "Pulling"
      git pull
    else
      echo "Skipping because it doesn't look like it has a .git folder."
    fi
    echo "Done at `date`"
    echo
  fi
done

Very useful, thanks

Thanks buddy.

Thank you.

@mnem Can you get me a script similar to this wherein if I am on a different branch other than master, it checks out to master, pulls master, and checkout to my branch and merge master in for all subfolders? Thanks

@a2441918 It should be straightforward for you to add that. Git works with a local database, so all you need to do is update origin/master and then merge that in - you don't need to change branches. After the git fetch, that local database is up to date, so you could add something like git merge origin/master, which will attempt to merge the newly updated origin/master to whatever branch you are on. Of course the merge may fail, so you'd have to decide how you wanted the script to behave in those situations.

Good stuff mate!

Following is one way to have it looping continuously, required a do-while and one additional line of code:

#!/bin/bash
################
# Uncomment if you want the script to always use the scripts
# directory as the folder to look through
#REPOSITORIES="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"
i=1
while [ "$i" -ne 0 ]
do
REPOSITORIES=`pwd`
IFS=$'\n'
for REPO in `ls "$REPOSITORIES/"`
do
  if [ -d "$REPOSITORIES/$REPO" ]
  then
    echo "Updating $REPOSITORIES/$REPO at `date`"
    if [ -d "$REPOSITORIES/$REPO/.git" ]
    then
      cd "$REPOSITORIES/$REPO"
      git status
      echo "Fetching"
      git fetch
      echo "Pulling"
      git pull
      cd ..
    else
      echo "Skipping because it doesn't look like it has a .git folder."
    fi
    echo "Done at `date`"
    echo
  fi
done
sleep 10
done

Runs every 10 seconds, change the number in sleep 10 according to your needs. make it executable with sudo chmod +x yourFIleName.sh , then run it with $ ./yourfileName.sh - cool hack: If you start a screen you can have it running in the background: screen -S autopuller and then run the script. To detach from the screen, press Ctrl + A and Ctrl + D !

Recursive version of script

#!/bin/bash

################

sync_directory() {
  IFS=$'\n'

  for REPO in `ls "$1/"`
  do
    if [ -d "$1/$REPO" ]
    then
      echo "Updating $1/$REPO at `date`"
      if [ -d "$1/$REPO/.git" ]
      then
        git -C "$1/$REPO" pull
      else
        sync_directory "$1/$REPO" 
      fi
      echo "Done at `date`"
    fi
  done
}

REPOSITORIES="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"

sync_directory $REPOSITORIES

I have a similar one, but I think the difference is that mine supports default branches

Thanks

Thank you!
