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
–dereference
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)
–no-preserve-root
do not treat ‘/’specially (the default)
–preserve-root
fail to operate recursively on ‘/’
-f, –silent, –quiet
suppress most error messages
–reference=RFILE
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 thefinal 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”.
