OSX: find,xargs guru?
hello,

bash 4.2+
osx 10.11.6

i looking for a nice compact one-liner and need a little help using find and xargs

i'm writing a script to recursively search through directories looking for git and hg repos and update them.

this bit of code searches and finds them git repos.

Code:
find `pwd` -depth -name .git -type d |  xargs -P 8 -I {} dirname {}

i want to operate several git commands once in the directory.

for example,
Code:
git stash; git pull; git submodule update; git gc

how to
Code:
pushd

a directory? run the commands? and then
Code:
 popd

the directories?

continue to next? how to handle any if any errors if git chokes? if error go to next directory?

thanks

git-lost-found

GIT-LOST-FOUND(1)						    Git Manual							 GIT-LOST-FOUND(1)

NAME

       git-lost-found - Recover lost refs that luckily have not yet been pruned

SYNOPSIS

       git lost-found

DESCRIPTION

       NOTE: this command is deprecated. Use git-fsck(1) with the option --lost-found instead.

       Finds dangling commits and tags from the object database, and creates refs to them in the .git/lost-found/ directory. Commits and tags that
       dereference to commits are stored in .git/lost-found/commit, and other objects are stored in .git/lost-found/other.

OUTPUT

       Prints to standard output the object names and one-line descriptions of any commits or tags found.

EXAMPLE

       Suppose you run git tag -f and mistype the tag to overwrite. The ref to your tag is overwritten, but until you run git prune, the tag
       itself is still there.

	   $ git lost-found
	   [1ef2b196d909eed523d4f3c9bf54b78cdd6843c6] GIT 0.99.9c
	   ...

       Also you can use gitk to browse how any tags found relate to each other.

	   $ gitk $(cd .git/lost-found/commit && echo ??*)

       After making sure you know which the object is the tag you are looking for, you can reconnect it to your regular .git/refs hierarchy.

	   $ git cat-file -t 1ef2b196
	   tag
	   $ git cat-file tag 1ef2b196
	   object fa41bbce8e38c67a218415de6cfa510c7e50032a
	   type commit
	   tag v0.99.9c
	   tagger Junio C Hamano <junkio@cox.net> 1131059594 -0800

	   GIT 0.99.9c

	   This contains the following changes from the "master" branch, since
	   ...
	   $ git update-ref refs/tags/not-lost-anymore 1ef2b196
	   $ git rev-parse not-lost-anymore
