Run git pull over all subdirectories

Question

How can I update  multiple git repositories from their shared parent s directory without cd ing into each repo s root directory  I have the following which are all separate git repositories  not submodules     plugins cms  plugins admin  plugins chart   I want to update them all at once or at least simplify my current workflow   cd   plugins admin git pull origin master cd    chart git pull   etc

Original answer 2010   If all of those directories are separate git repo  you should reference them as submodules   That means your  origin  would be that remote repo  plugins  which only contains references to subrepos  cms    admin    chart    A git pull followed by a git submodule update would achieve what your are looking for     Update January 2016   With Git 2 8  Q1 2016   you will be able to fetch submodules in parallel     with git fetch --recurse-submodules -j2  See  How to speed up   parallelize downloads of git submodules using git clone --recursive

Actually  if you don t know if the subfolders have a git repo or not  the best would be to let find get the repos for you   find   -type d -name  git -exec git --git-dir    --work-tree  PWD       pull origin master      The PowerShell equivalent would be   Get-ChildItem -Recurse -Directory -Hidden  -Filter  git   ForEach-Object    amp  git --git-dir       FullName   --work-tree    Split-Path    FullName -Parent   pull origin master

My humble construction that    shows the current path  using python  convenient and just works  see How to get full path of a file   looks directly for  git subfolder  low chance to emit a git command in a non-git subfolder gets rid of some warnings of find   as follow   find         -maxdepth 2 -type d       -name   git        -execdir python -c  import os  print os path abspath                 -execdir git pull      Of course  you may add other git commands with additional -execdir options to find  displaying the branch for instance   find         -maxdepth 2 -type d       -name   git        -execdir python -c  import os  print os path abspath                 -execdir git branch        -execdir git pull

You can try this  find   -type d -name  git -exec sh -c  cd             amp  amp  pwd  amp  amp  git pull       Also  you can add your customized output by adding one more  amp  amp  argument like   find   -type d -name  git -exec sh -c  cd             amp  amp  pwd  amp  amp  git pull  amp  amp  git status

This should happen automatically  so long as cms  admin and chart are all parts of the repository   A likely issue is that each of these plugins is a git submodule   Run git help submodule for more information   EDIT  For doing this in bash   cd plugins for f in cms admin chart do    cd  f  amp  amp  git pull origin master  amp  amp  cd    done

The mr utility  a k a   myrepos  provides an outstanding solution to this very problem  Install it using your favorite package manager  or just grab the mr script directly from github and put it in  HOME bin or somewhere else on your PATH  Then  cd to the parent plugins folder shared by these repos and create a basic  mrconfig file with contents similar to the following  adjusting the URLs as needed      File   mrconfig  cms  checkout   git clone  https    lt username gt  github com  lt username gt  cms   cms    admin  checkout   git clone  https    lt username gt  github com  lt username gt  admin   admin    chart  checkout   git clone  https    lt username gt  github com  lt username gt  chart   chart    After that  you can run mr up from the top level plugins folder to pull updates from each repository   Note that this will also do the initial clone if the target working copy doesn t yet exist   Other commands you can execute include mr st  mr push  mr log  mr diff  etc   run mr help to see what s possible  There s a mr run command that acts as a pass-through  allowing you to access VCS commands not directly suported by mr itself  e g   mr run git tag STAGING 081220015   And you can even create your own custom commands that execute arbitrary bits of shell script targeting all repos   mr is an extremely useful tool for dealing with multiple repos  Since the plugins folder is in your home directory  you might also be interested in vcsh  Together with mr  it provides a powerful mechanism for managing all of your configuration files  See this blog post by Thomas Ferris Nicolaisen for an overview

A bit more low-tech than leo s solution   for i in    git  do   echo  i  cd  i     git pull     done   This will update all Git repositories in your working directory  No need to explicitly list their names   cms    admin    chart    The  cd  command only affects a subshell  spawned using the parenthesis

Run the following from the parent directory  plugins in this case   find   -type d -depth 1 -exec git --git-dir     git --work-tree  PWD    pull origin master      To clarify    find   searches the current directory -type d to find directories  not files -depth 1 for a maximum depth of one sub-directory -exec       runs a custom command for every find git --git-dir     git --work-tree  PWD    pull git pulls the individual directories   To play around with find  I recommend using echo after -exec to preview  e g    find   -type d -depth 1 -exec echo git --git-dir     git --work-tree  PWD    status      Note  if the -depth 1 option is not available  try -mindepth 1 -maxdepth 1

If you have a lot of subdirs with git repositories  you can use parallel  ls   parallel -I   -j100     if   -d     git    then     echo Pulling        git -C    pull  gt   dev null  amp  amp  echo  pulled     echo  error       else      echo    is not a  git directory   fi
