emuga-target(1)

NAME

emuga-groupgen - Generate group information.

USAGE

emuga-target [options] target [ [options] target [...] ]

DESCRIPTION

Emuga target can help you to set up a target (directory or file) so that two groups have inpact on the permissions for it. You can specify one read group and one write group.

OPTIONS

  --dl nr | --debug-level nr
        Debug level (for debugging).
  --ql nr | --quit-level nr
        Quit level (for debugging).
  -N    Not nice (chown, chgrp for all groups).
  -n    Nice (chown, chgrp only for the group owning the target), default.
  -R    Do not run chmod, chgrp recursively.
  -S    Do not change the sgid bit, see -s below.
  -s    Change the sgid bit for the writegroup (default). This affects
        recursive changes for writegroup and also recursive changes when
        it is removed or replaced with a readgroup.
  -r readgroup
        The group defined here is the one that should have read
        permission on the target (and possibly subtargets).
  -w writegroup
        The group that should have write permission to the target
        (and possibly subtargets).
  --fix
        Fix problems that can be fixed automaticly (defult no).
  --help
        Print this help.

target:
The target is a file or directory. To make it really usable directories are
preferred.

  If no read or write-group is specified it only prints the old
  permissions of the target(s).

Observe that the created directory structure makes an AND operation of the read and write access. The write permission implies read access but you can restrict read access by not adding the user to the read group if you want to do that (the effect is that you will probably not get write access either).

Setting a empty ("") read or write group will unset that group. Note that there is no way to unset a group. You have to specify new permissions.
