Hi all,
I am experiencing a problem when parsing the results of `git status`.
My primary goal is to parse the output of `git status`
programmatically, so I am trying to parse the result of `git status
--porcelain=2 -z`.
According to the docs [here](https://git-scm.com/docs/git-status), the
`-z` option only changes the entry terminations and implies the
`--porcelain=v1` output format if no other format is given. However,
the result shows that the path returned is a relative path to the repo
root rather than the current directory when using `-z`. Simply using
`git status --porcelain=2` returns the relative path to the current
directory.
I am wondering how to force the path to be relative to the current
directory (for easier cutting and pasting) rather than the repo root
when using `git status --porcelain=2 -z`. I would really appreciate it
if you could help me!
Regards,
Zhisheng

Interesting finding. Here is what I tried in my working tree, where
I have a few cruft files left at the top, and ran these commands
inside the 't/' subdirectory:
$ git status --porcelain=1
?? +ps8-v2-reftable-iterator-reuse
?? :runme.sh
: git t/master; git status --porcelain=2
? ../+ps8-v2-reftable-iterator-reuse
? ../:runme.sh
: git t/master; git status --porcelain=1 -z | tr '\0' '\n'
?? +ps8-v2-reftable-iterator-reuse
?? :runme.sh
: git t/master; git status --porcelain=2 -z | tr '\0' '\n'
? +ps8-v2-reftable-iterator-reuse
? :runme.sh
I haven't dug into the history to see if these inconsistencies in
behaviour are deliberate, but I somehow suspect that the output from
"--porcelain=2" without "-z" is mistaken. As the porcelain output
is designed to be machine parseable with or without "-z" (and the
reader of the output, the implementation of a Porcelain command, is
responsible for turning it into relative if it prefers), it would be
a mistake to turn relative output on based on the lack of "-z".
Not that we can "fix" the output from "--porcelain=2" at this point.
To changge them to uniformly show absolute (or relative for that
matter), we'd need "--porcelain=3" to preserve these inconsistency
output because it is very certain that existing users and scripts
already rely on it.
Thanks.

Hi Junio,
Thank you for the quick response! That is exactly what I have encountered.
I understand that it is highly probable that the result of `git status
--porcelain=2` is unexpected, and it may not be fixed due to
consistency.
Thanks a lot!
