关于chmod的问题
想问一下,用chmod把一个文件的权限赋给指定的用户，比如，有一个a文件，要把它的r属性赋给test用户，只是test用户，而不是它所在的组，这样的命令怎么写？在网上查了N多资料，好像只看到ugo这种写法，好像没看到指定用户名的写法。。。。 chmod只能修改权限，不能更改所有者，更改所有者的命令是：
[code]
#chown user:group /directory/file
[/code]
在线手册man是这样定义：
[code]
CHOWN(1) User Commands CHOWN(1)
NAME
chown - change file owner and group
SYNOPSIS
chown [OPTION]... [OWNER][:[GROUP]] FILE...
chown [OPTION]... --reference=RFILE FILE...
DESCRIPTION
This manual page documents the GNU version of chown. chown changes the
user and/or group ownership of each given file. If only an owner (a
user name or numeric user ID) is given, that user is made the owner of
each given file, and the files' group is not changed. If the owner is
followed by a colon 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 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's login group. If the colon and group are given, but the
owner is omitted, only the group of the files is changed; in this case,
chown performs the same function as chgrp. If only a colon is given,
or if the entire operand is empty, neither the owner nor the group is
changed.
