NAMEchgrp — change group
|chgrp||[ -fhvx][ -R [ -H | -L | -P]] group file ...|
DESCRIPTIONThe chgrp utility sets the group ID of the file named by each file operand to the group ID specified by the group operand.
The following options are available:
- If the -R option is specified, symbolic links on the command line are followed. (Symbolic links encountered in the tree traversal are not followed.)
- If the -R option is specified, all symbolic links are followed.
- If the -R option is specified, no symbolic links are followed. This is the default.
- Change the group ID for the file hierarchies rooted in the files instead of just the files themselves.
- The force option ignores errors, except for usage errors and does not query about strange modes (unless the user does not have proper permissions).
- If the file is a symbolic link, the group ID of the link itself is changed rather than the file that is pointed to.
- Cause chgrp to be verbose, showing files as the group is modified. If the -v flag is specified more than once, chgrp will print the filename, followed by the old and new numeric group ID.
- File system mount points are not traversed.
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 super-user.

EXIT STATUSThe chgrp utility exits 0 on success, and >0 if an error occurs.
COMPATIBILITYIn previous versions of this system, symbolic links did not have groups.
The -v and -x options are non-standard and their use in scripts is not recommended.
STANDARDSThe chgrp utility is expected to be IEEE Std 1003.2 (“POSIX.2”) compatible.
