.TH CHGRP 1 .SH NAME chgrp \- change file's group or owner .SH SYNOPSIS .B chgrp [ .B -uo ] .I id .I file ... .SH DESCRIPTION .I Chgrp changes the group ownership of each .I file to the given .IR id , if the file's server permits it. The .B -u and .B -o options are equivalent and cause .I chgrp to change file ownership instead, if the file's server permits it. .PP 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 documented by the device's manual page. See .IR sys-stat (2) for the variations amongst host operating systems. .SH SOURCE .B /appl/cmd/chgrp.b .SH SEE ALSO .IR chmod (1), .IR ls (1) .IR sys-stat (2)
