Name

chgrp - change group ownership

Synopsis

chgrp [\,OPTION\/]... \,GROUP FILE\/... chgrp [\,OPTION\/]... \,--reference=RFILE FILE\/...

Description

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

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

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

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

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

--no-preserve-root do not treat '/' specially (the default)

--preserve-root fail to operate recursively on '/'

--reference=\,RFILE\/ use RFILE's group rather than specifying a GROUP value

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

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.

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

-L traverse every symbolic link to a directory encountered

-P do not traverse any symbolic links (default)

--help display this help and exit

--version output version information and exit

Examples

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

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