Again, it only happens if a pull actually brought in new stuff. Finally, the final true is ensuring that script continues on errors. To make this work, everything in the iteration must be wrapped in the double-quotes and the Git commands are wrapped in parentheses operator precedence.
Finally, a commit with some message explaining that the parent repository was updated. This commit will be ignored by default, if nothing was done. Push this to origin, and you're done. I have a script running this in a Jenkins job that chains to a scheduled automated deployment afterwards, and it works like a charm. Merged by Junio C Hamano -- gitster -- in commit f1c9f6c , 25 Apr It should be quiet before fc1b submodule : port submodule subcommand ' foreach ' from shell to C, , Git v2.
This happens because parseopt in submodule--helper will try to parse both --quiet options as if they are foreach's options, not git-pull 's. The parsed options are removed from the command line. So when we do pull later, we execute just this.
When calling submodule helper, adding " -- " in front of " git pull " will stop parseopt for parsing options that do not really belong to submodule--helper foreach. There are also a couple usage string update while I'm looking at them. But the point still stands, git-submodule has parsed and classified what are options, what are paths.
And Git 2. See commit 30db18b 24 Jun by Morian Sonnet momoson. Merged by Junio C Hamano -- gitster -- in commit eecb , 09 Jul The reason for this is, that above call is internally translated into a call to submodule--helper:. This call starts by executing the subcommand with its option inside the first level submodule and continues by calling the next iteration of the submodule foreach call.
Note that the double dash in front of the subcommand is missing. Hence, the unknown option is complained about now, as the argument parsing is not properly ended by the double dash. This commit fixes the problem by adding the double dash in front of the subcommand during the recursion. Note that, before Git 2. See commit 3ad 30 Sep by Theodore Dubois tbodt. Merged by Junio C Hamano -- gitster -- in commit cd14 , 05 Oct Pass the --quiet option down when invoking " rebase " and " merge ".
Also fix the parsing of git submodule update man -v. When e84c3cf3 " git-submodule. In my case, I wanted git to update to the latest and at the same time re-populate any missing files.
The following restored the missing files thanks to --force which doesn't seem to have been mentioned here , but it didn't pull any new commits:. It will get a branch of the main Git repository and then for each submodule will make a pull of the same branch. Update the registered submodules, i. This will make the submodules HEAD be detached unless --rebase or --merge is specified or the key submodule.
So, git submodule update does checkout, but it is to the commit in the index of the containing repository. It does not yet know of the new commit upstream at all. So go to your submodule, get the commit you want and commit the updated submodule state in the main repository and then do the git submodule update.
Thanks to Mark Jaquith. If you are looking to checkout master branch for each submodule -- you can use the following command for that purpose:.

The git submodule update command does the following: Update the registered submodules to match what the superproject expects by cloning missing submodules and updating the working tree of the submodules.
On the other side, the command git submodule foreach : Evaluates an arbitrary shell command in each checked out submodule. For further details, see the link above. It would be worth it to explain the differences.

If it's the first time you check-out a repo you need to use --init first: git submodule update --init --recursive For git 1.
Henrik Gustafsson Henrik Gustafsson Probably you should use git submodule update --recursive nowadays. Just to add, blindly sticking origin master at the end of this command might have unexpected results if some of your submodules are tracking a different branch or location name of that particular submodule. Obvious to some, but probably not to everyone. Just to clarify for everyone. It does NOT pull the latest commits for each submodule. Only then will you get pending changes in the parent repo with updated revision hashes for submodules.

To initialize them you need run git submodule update --recursive --init. Quote from manual : If the submodule is not yet initialized, and you just want to use the setting as stored in.

MichaelScottCuthbert thanks, i'm sure in another 3 years this command will be crazy too — abc Nevertheless, this does not checkout the latest revision from the submodule, only the latest revision that the parent is tracking. NathanOsman which is what you want If you are the maintainer of the parent you can update those yourself and commit them. Yes, but from my understanding, that isn't what the OP wanted.
