# chgrp(1)

## NAME

         chgrp - change group

## SYNOPSIS

         chgrp [-R] [owner:]group file ...

## OPTIONS

         -R   Change directory hierarchies

## EXAMPLES

         chgrp system file1 file2
                             # Make system the group of the files

         chrgp -R other dir1 # Make other the group of all files below dir1

## DESCRIPTION

         The group field (and optionally  owner  field)  of  the  named  files  is
         changed  to  group  and owner . Alternatively, a decimal gid (uid) may be
         specified instead of a group name.  If the -R flag is used,  the  changes
         will  be  applied recursively to all files in named directories. Only the
         superuser may execute this command to set arbitrary groups. Normal  users
         can  only  change  the group if they own the file, and the group is their
         own group (Minix), or one of their supplementary groups (Minix-vmd).
