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