CHGRP(1) BSD Reference Manual CHGRP(1)NAMEchgrp - change group
SYNOPSISchgrp [-R [-H | -L | -P]] [-fh] group file [...]
DESCRIPTIONchgrp 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.
