Yeah, that won't work, because there is no such option. We do
have "--prefix", but I suspect that's not flexible enough for
what you want.
If you only need a single subdirectory with a custom prefix you
could do something like this (variables only used to keep the lines
short):
$ subdir=WebPortal/Templates $ prefix=myPath/myWeb/Templates/ $ (cd
"$subdir"&& git archive --prefix="$prefix" HEAD)>my.tar
The output file can be specified with -o as well, of course, but
you'd either need to use an absolute path or add "../" for each
directory level you descend into (-o ../../my.tar in this case).
Couldn't you also do:
git archive --prefix=$prefix HEAD:$subdir>my.tar
? I guess that loses the pax header with the commit sha1 in it,
though, because you are feeding a straight tree instead of a commit.
We didn't when git-archive was written, but these days we have
get_sha1_with_context to remember incidental things about an object
we look up. It should perhaps remember the commit (if any) we used to
reach a treeish, and then the above command line could still insert
the pax header.
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?
