Use core.filemode.
With "[core] filemode = false", you can tell git to ignore differences in the working tree file only in executable bit. * "git-update-index --refresh" does not say "needs update" if index entry and working tree file differs only in executable bit. * "git-update-index" on an existing path takes executable bit from the existing index entry, if the path and index entry are both regular files. * "git-diff-files" and "git-diff-index" without --cached flag pretend the path on the filesystem has the same executable bit as the existing index entry, if the path and index entry are both regular files. If you are on a filesystem with unreliable mode bits, you may need to force the executable bit after registering the path in the index. * "git-update-index --chmod=+x foo" flips the executable bit of the index file entry for path "foo" on. Use "--chmod=-x" to flip it off. Note that --chmod only works in index file and does not look at nor update the working tree. So if you are on a filesystem and do not have working executable bit, you would do: 1. set the appropriate .git/config option; 2. "git-update-index --add new-file.c" 3. "git-ls-files --stage new-file.c" to see if it has the desired mode bits. If not, e.g. to drop executable bit picked up from the filesystem, say "git-update-index --chmod=-x new-file.c".
