CHGRP(1) BSD General Commands Manual CHGRP(1) NAME chgrp -- change group SYNOPSIS chgrp [-R [-H | -L | -P]] [-f] [-h] group files ... DESCRIPTION The chgrp utility sets the group ID of the file named by each file oper- and to the group ID specified by the group operand. Options: -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 and doesn't query about strange modes (unless the user does not have proper permissions). -h If the file is a symbolic link, the group ID of the link itself is changed rather than the file that is pointed to. 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 op- erand 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 super-user. The chgrp utility exits 0 on success, and >0 if an error occurs. COMPATIBILITY In previous versions of this system, symbolic links did not have groups.
