HEAD:$subdir worked on my bare repo. I ran it for each transformant pathspec and then combined the archives with tar --catenate:
# git archive --format=tar --prefix=myWeb/myRoot/myAPP/Templates/ HEAD:WebPortal/Templates/ >myAPP.myTag.tar # git archive --format=tar --prefix=opt/mySTUFF/v01/SCRIPTS/ HEAD:SCRIPTS/ >SCRIPTS.tar # tar --file=myAPP.myTag.tar -A SCRIPTS.tar
However, the permissions also need to change to 777 and tar --mode would not effect this in combination with --catenation or -x. Is there a way I can change the permissions without having to untar->chmod->retar, and without having to use a non-bare repo as an intermediary?
