|
|
|
|
|
The chgrp utility sets the group ID of the file named by each
|
|
|
|
|
.Ar file
|
|
|
|
|
operand to the
|
|
|
|
|
.Ar group
|
|
|
|
|
ID specified by the group operand.

Recursively change file group IDs.
|
|
|
|
|
For each
|
|
|
|
|
.Ar file
|
|
|
|
|
operand that names a directory, chgrp changes the
|
|
|
|
|
group of the directory and all files in the file
|
|
|
|
|
hierarchy below it.
|
|
|
|
|
When symbolic links are encountered, their group is changed,
|
|
|
|
|
but they are not traversed.

|
|
|

The force option ignores errors, except for usage errors and doesn't
|
