chgrp - change group ownership of files
Návod, kniha: General Commands Manual
chgrp [options] group file...
POSIX options:
[-R] [--]
POSIX 1003.1-2001 options:
[-hHLPR]
GNU group denotation:
[--reference=rfile]
GNU options (shortest form):
[-cfvR] [--help] [--version] [--]
chgrp changes the group ownership of each given
file to
group, which can be either a group name or a numeric group ID.
- -R
- Recursively change the group ownership of directories and
their contents. (And continue even when errors are encountered.)
- --
- Terminate option list.
- -h
- For each file operand given that is a symlink, change the
group ownership of the symlink itself, rather than the object it points
to. If the system does not support a group ownership for symlinks, do
nothing for a symlink.
- -H (half-logical)
- (When given together with -R.) For each file operand
given that is a symlink to a directory, change the group ownership of the
directory and all files in the file hierarchy below it.
- -L (logical)
- (When given together with -R.) For each file, either
command line operand or encountered during the tree walk, that is a
symlink to a directory, change the group ownership of the directory and
all files in the file hierarchy below it.
- -P (physical)
- (When given together with -R.) For each file, either
command line operand or encountered during the tree walk, that is a
symlink, change the group ownership of the symlink itself, rather than the
object it points to. If the system does not support a group ownership for
symlinks, do nothing for a symlink. This is the default.
- -R
- Recursively change the group ownership of directories and
their contents.
A GNU extension (new in fileutils 4.0) allows one to use
--reference=rfile as a group description: the same group as that
of
rfile.
- -c, --changes
- Verbosely describe the action for each file whose
group actually changes.
- -f, --silent, --quiet
- Do not print error messages about files whose group cannot
be changed.
- -h, --no-dereference
- Act on symbolic links themselves instead of what they point
to. Only available if the lchown system call is provided.
- -v, --verbose
- Verbosely describe the action or non-action taken for every
file.
- -R, --recursive
- Recursively change the group ownership of directories and
their contents.
- --help
- Print a usage message on standard output and exit
successfully.
- --version
- Print version information on standard output, then exit
successfully.
- --
- Terminate option list.
The variables LANG, LC_ALL, LC_CTYPE and LC_MESSAGES have the usual meaning. For
an XSI-conforming system: NLSPATH has the usual meaning.
POSIX 1003.2 only requires the -R option. Use of other options may not be
portable.
This page describes
chgrp as found in the fileutils-4.0 package; other
versions may differ slightly.
