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 RFILEs 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.
-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".
