Guys, Trying to sort out my git issues, I have been picking through switch_all_submodules_to_head_and_clean. I cannot understand what the purpose of the line: git submodule foreach "$THISSCRIPT $gituser" That line causes git to step through each of its submodules and call: "switch_all_submodules_to_head_and_clean <gitUser>" Why? The script has already done everything at least once before? Dissecting the script it does: git reset --hard HEAD git clean -dxf git pull git reset --hard HEAD git clean -dxf sed -i "s/system@/$gituser@/g" .gitmodules # or 's/system@//g' git submodule init git submodule update git submodule foreach "git checkout master" git submodule foreach "git pull" then it does: git submodule foreach "$THISSCRIPT $gituser" Which causes this script to be run all over again on each submodule... I have changed this version of my script as follows and it seems to run on each submodule anyway: git reset --hard HEAD git clean -dxf git pull git reset --hard HEAD git clean -dxf sed -i "s/system@/$gituser@/g" .gitmodules # or 's/system@//g' git submodule init git submodule update --recursive git submodule foreach --recursive "git checkout master" git submodule foreach --recursive "git pull" git pull gets everything: 16:32 archangel:/dat_f/tde/git> git pull remote: Counting objects: 14, done remote: Finding sources: 100% (12/12) remote: Total 12 (delta 8), reused 12 (delta 8) Unpacking objects: 100% (12/12), done.
