Hi,
As per our conversation with Bruno I was thinking if it would make a sense to
extend support of ACLs in gnulib/coreutils, mainly covering "ls" (1st stage)
and "chmod" (2nd stage) with the goal to have the ACLs better understandable
for end users.
For "ls" we would:
- Introduce a new flag "-V" that would work like "-l" but also append text
interpretation of ACLs as in Solaris, i.e.:
# ls -V
total 7
-rw-r--r--+ 1 root root 5 Jan 4 09:11 acl
user:ondrej:rwx-----------:-------:allow
owner@:rw-p--aARWcCos:-------:allow
group@:r-----a-R-c--s:-------:allow
everyone@:r-----a-R-c--s:-------:allow
For "chmod" we would add new option "A" that would allow modify ACEs like in
Solaris:
# chmod A+user:marks:rw- file.1
Technical implementation:
- I'd like to support NFSv4 ACLs, but since we have no library for it, then we
would need to provide some parsing code for it and stick in Gnulib - we have
something in "file-has-acl.c" already and it would be a good starting point.
- file_has_acl() function would need to be modified slightly to return 2 in
case NFSv4 acls were found (this is backward compatible).
For Posix acls we would use the existing libacl.
Is this something I would find support in both coreutils and Gnulib?
Thanks
Ondrej
