改變檔案所屬的使用者和組(chown and chgrp)

DESCRIPTION
       This manual page documents the GNU version of chown.  chown changes the
       user and/or group ownership of each given file, according to its  first
       non-option  argument,  which is interpreted as follows.  If only a user
       name (or numeric user ID) is given, that user is made the owner of each
       given  file,  and the files鈥?group is not changed.  If the user name is
       followed by a colon or dot and a group name (or numeric group ID), with
       no  spaces between them, the group ownership of the files is changed as
       well.  If a colon or dot but no group name follows the user name,  that
       user  is  made  the  owner  of  the files and the group of the files is
       changed to that user鈥檚 login group.  If the colon or dot and group  are
       given,  but  the  user  name is omitted, only the group of the files is
       changed; in this case, chown performs the same function as chgrp.
