how to let gui git accept multiple file selection to work with a custom tool?
in .gitconfig we can create this:
[guitool "create backup"]
cmd = cp -vf \"$FILENAME\" \"$FILENAME.bkp\"
noconsole = yes
needsfile = yes
but I need to use that with 20 files...
how to do it for 20 files clicking only once in the custom tool using git gui?
I tried the above described but the custom tool will only work on the first selected file.
I found also that staging them to commit will update the .git/index binary file, so I could grep thru it, but it is binary and difficult to work with (but not impossible), so I could create a script that looks into it and does the backup, but that is a hack.
So I wonder if there is some proper way to do that? (tho, a hack could suffice also if it works well :))
