CHGRP(1)                   OpenBSD Reference Manual                   CHGRP(1)


NAME

     chgrp - change group


SYNOPSIS

     chgrp [-h] [-R [-H | -L | -P]] group file ...


DESCRIPTION

     chgrp sets the group ID of the specified files.

     The options are as follows:

     -H      If the -R option is specified, symbolic links on the command line
             are followed.  (Symbolic links encountered in the tree traversal
             are not followed.)

     -h      Change the group ID of the specified symbolic link.  The -h and
             -R options are mutually exclusive.

     -L      If the -R option is specified, all symbolic links are followed.

     -P      If the -R option is specified, no symbolic links are followed.

     -R      Change the group ID for the file hierarchies rooted in the files
             instead of just the files themselves.

     The -H, -L, and -P options are ignored unless the -R option is specified.
     In addition, these options override each other and the command's actions
     are determined by the last one specified.

     The group operand can be either a group name from the group database, or
     a numeric group ID.  If a group name is also a numeric group ID, the
     operand is used as a group name.

     The user invoking chgrp must belong to the specified group and be the
     owner of the file, or be the superuser.
