- .TH CHGRP 1
- .SH NAME
- chgrp \- change file group
- .SH SYNOPSIS
- .B chgrp
- [
- .B -ou
- ]
- .I group file ...
- .SH DESCRIPTION
- The group of
- each named file
- is changed to
- .IR group ,
- which should be a name known to the server holding the file.
- .PP
- A file's group can be changed by the file's owner, if the
- owner is a member of the new group,
- or by the leader of both
- the file's current group and the new group.
- .PP
- The
- .B -o
- and
- .B -u
- option are synonyms; they specify that the
- .I owner
- is to be set, rather than the group.
- They are ineffectual unless the file server is in the bootstrap
- state that permits changing file ownership.
