How do I revert my changes to a git submodule

Question

I have a git submodule  RestKit  which I have added to my repo   I accidentally changed some files in there and I d like to go back to the source version  In order to do that  I tried to run   Mac app-ios user  git submodule update RestKit   But as you can see here  this did not work as it is still  modified content    Mac app-ios user  git status         modified    RestKit  modified content    Even   Mac app-ios user  git submodule update -f RestKit    doesn t revert locally modified files  How do I reset the content of that submodule

do 4 steps sequential   git submodule foreach git reset --hard HEAD git submodule update git submodule foreach  git checkout master  git pull  git submodule foreach git clean -f

Move into the submodule s directory  then do a git reset --hard to reset all modified files to their last committed state  Be aware that this will discard all non-committed changes

Well for me  having  git reset --hard   just reset the submodule to the state where it checked out  not necessary to the main s repo referenced commit state  I ll still have  modified contents  like OP said  So  in order to get the submodule back to the corrects commit  I run   git submodule update --init   Then when I do git status  it s clean on the submodule

This worked for me  including recursively into submodules  perhaps that s why your -f didn t work  cause you changed a submodule inside the submodule    git submodule update -f --recursive

Since Git 2 14  Q3 2017   you don t have to go into each submodule to do a git reset  as in git submodule foreach git reset --hard   That is because git reset itself knows now how to recursively go into submodules   See commit 35b96d1  21 Apr 2017   and commit f2d4899  commit 823bab0  commit cd279e2  18 Apr 2017  by Stefan Beller  stefanbeller    Merged by Junio C Hamano -- gitster -- in commit 5f074ca  29 May 2017        builtin reset  add --recurse-submodules switch   git-reset is yet another working tree manipulator  which should be taught about submodules      When a user uses git-reset and requests to recurse into submodules    this will reset the submodules to the object name as recorded in the   superproject  detaching the HEADs    Warning  the difference between    git reset --hard --recurse-submodule and git submodule foreach git reset --hard   is that the former will also reset your main parent repo working tree  as the latter would only reset the submodules working tree  So use with caution

For git  lt   2 13 these two commands combined should reset your repos with recursive submodules   git submodule foreach --recursive git reset --hard git submodule update --recursive --init

A more fail-safe method than all previous answers   git submodule deinit -f   git submodule update --init   The first command completely  unbinds  all submodules  the second then makes a fresh checkout of them  It takes longer than the other methods  but will work whatever the state of your submodules

This works with our libraries running GIT v1 7 1  where we have a DEV package repo and LIVE package repo   The repositories themselves are nothing but a shell to package the assets for a project  all submodules     The LIVE is never updated intentionally  however cache files or accidents can occur  leaving the repo dirty   New submodules added to the DEV must be initialized within LIVE as well   Package Repository in DEV  Here we want to pull all upstream changes that we are not yet aware of  then we will update our package repository     Recursively reset to the last HEAD git submodule foreach --recursive git reset --hard    Recursively cleanup all files and directories git submodule foreach --recursive git clean -fd    Recursively pull the upstream master git submodule foreach --recursive git pull origin master    Add   Commit   Push all updates to the package repo git add   git commit -m  Updates submodules  git push      Package Repository in LIVE  Here we want to pull the changes that are committed to the DEV repository  but not unknown upstream changes     Pull changes git pull    Pull status  this is required for the submodule update to work  git status    Initialize   Update  git submodule update --init --recursive

If there s changes in your submodules  then use git submodule foreach --recursive git reset --hard  If your changes are remote submodule changes  then use git submodule update --init  If these changes have been committed  then use git reset --hard git submodule update --init

If you want to discard all changes in the entire repository along with sub modules  you can use   git restore   --recurse-submodules   This will undo all changes made in repository and in sub modules

First try this  as others have said   git submodule update --init   If that doesn t work  change to the submodule directory and use the following command to see if there are any changes to the submodule   git status   If there are changes to your submodule  get rid of them   Verify that you can don t see any changes when you run  git status    Next  go back to the main repository and run  git submodule update --init  again

If you want to do this for all submodules  without having to change directories  you can perform  git submodule foreach git reset --hard  You can also use the recursive flag to apply to all submodules   git submodule foreach --recursive git reset --hard
