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

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

Thank you!
