chown - (BSD) change file ownwer
owner[.group] file ...
Chown changes the owner of the files to owner, and, if
group is present, the group-ID of the files to group.
Both owner and group may be either a decimal UID
/ GID or a login / group name found in the password file.
The following options are accepted:
- Do not display errors.
- When a symbolic link is encountered, change the owner and group of the
link itself, rather than the file it refers to.
- Recursively descend into each file operand. Whether owner and group
of a symbolic link are changed depends on the -h option, but the
link is not followed otherwise.
The following options have been introduced by POSIX.1-2001:
chown(2), passwd(5), group(5)
Permission to change owner and group is based either on historical System V
behaviour, which is to allow the owner of the file or a privileged user a
change to any value; or on historical BSD behaviour, which is
to restrict changing the owner to a privileged user and changing the group to
a group to which the file owner belongs.
