> Linux Man Page: "chgrp"


Search with Google


The Linux Documentation Project maintains an archive of snaphots of the (English language) core Linux manual pages that are maintained by Michael Kerrisk. Corrections and additions are welcome, but review the "Help Wanted" list, first.

Man pages belonging to programs are usually distributed together with those programs. Therefore, the core Linux man-pages mainly contains the pages for system calls and library routines, special devices, and file formats. However, it also contains documentation for a few programs, in cases where the authors or maintainers of the program do not distribute man pages themselves.

This page is part of release 3.11 of the Linux man-pages project. A description of the project, and information about reporting bugs, can be found at

chgrp - change group ownership


chgrp [OPTION]... GROUP FILE...
chgrp [OPTION]... --reference=RFILE FILE...


Change the group of each FILE to GROUP. With --reference, change the group of each FILE to that of RFILE.

-c, --changes
like verbose but report only when a change is made

affect the referent of each symbolic link (this is the default), rather than the symbolic link itself

-h, --no-dereference
affect each symbolic link instead of any referenced file (useful only on systems that can change the ownership of a symlink)

do not treat ‘/’ specially (the default)

fail to operate recursively on ‘/’

-f, --silent, --quiet
suppress most error messages

use RFILE’s group rather than specifying a GROUP value

-R, --recursive
operate on files and directories recursively

-v, --verbose
output a diagnostic for every file processed

The following options modify how a hierarchy is traversed when the -R option is also specified. If more than one is specified, only the final one takes effect.

if a command line argument is a symbolic link to a directory, traverse it

traverse every symbolic link to a directory encountered

do not traverse any symbolic links (default)

--help display this help and exit

output version information and exit


chgrp staff /u
Change the group of /u to “staff".

chgrp -hR staff /u
Change the group of /u and subfiles to “staff".
