] group file ...
chgrpsets the group ID of the specified files. The options are as follows:
-Roption is specified, symbolic links on the command line are followed. Symbolic links encountered in the tree traversal are not followed.
-Roptions are mutually exclusive.
-Roption is specified, all symbolic links are followed.
-Roption is specified, no symbolic links are followed.
-Poptions are ignored unless the
-Roption is specified; if none of them are given, the default is to not follow symbolic links. 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. By default,
chgrpclears the set-user-ID and set-group-ID bits on the file to prevent accidental or mischievous creation of set-user-ID and set-group-ID programs. This behaviour can be overridden by setting the sysctl(8) variable fs.posix.setuid to zero. The user invoking
chgrpmust belong to the specified group and be the owner of the file, or be the superuser.
chgrputility exits 0 on success, and >0 if an error occurs. chown(2), fts(3), group(5), passwd(5), symlink(7), chown(8)
chgrputility is compliant with the IEEE Std 1003.1-2008 (“POSIX.1”) specification.
