CHGRP(1)CHGRP(1)NAMEchgrp - change file's group or owner
SYNOPSISchgrp [ -uo ] id file ...
DESCRIPTION
Chgrp changes the group ownership of each file to the given id, if the
file's server permits it. The -u and -o options are equivalent and
cause chgrp to change file ownership instead, if the file's server per‐
mits it.
Normally, 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, but various underlying devices, file
servers and host operating systems might not permit the operation at
all. Group and ownership changes allowed by a given device are docu‐
mented by the device's manual page. See sys-stat(2) for the variations
amongst host operating systems.
