NAME    [Toc]    [Back]

     chgrp - change group

SYNOPSIS    [Toc]    [Back]

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

DESCRIPTION    [Toc]    [Back]

     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.)

     -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.

     -f       The  force  option ignores errors, except for usage
errors.

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

     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.

     The chgrp utility exits 0 on success or >0 if an  error  occurred.
