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, rather than the symbolic link itself (this is the default)
-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)
  fail to operate recursively on ‘/’
-f, --silent, --quiet
  suppress most error messages
  use RFILE’s group rather than the specifying 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
  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".
