在UNIX系统中输入命令"Is-altest"显示如下"-rwxr-xr-x3rootroot1024Sep1311:58test"对它的含义解释错误的是:

who 就可以的。举例如下：
-bash-3.00# who
root console Sep 27 11:02 (:0)
root pts/2 Sep 29 11:24 (135.251.29.191)
sunj pts/4 Sep 29 13:59 (135.251.29.25)
root pts/6 Sep 27 11:02 (:0.0)
root pts/7 Sep 27 11:02 (:0.0)

从上面可以看到，分别有2个用户，root和sunj从IP地址135.251.29.191和135.251.29.25登录了，登录时间也有。其它是在console口登录的 -- 这个是系统自己算的，其实你拔掉console口好久，它还是算在里面了的。

-bash-3.00# who -q
root root sunj root root
# users=5

还要其它信息，man who看一下，或看下下面的参数说明。
-bash-3.00# who -h
who: illegal option -- h

Usage: who [-abdHlmpqrstTu] [utmpx_like_file]
who -q [-n x] [utmpx_like_file]
who [am i]
who [am I]
a all (Abdlprtu options)
b boot time
d dead processes
H print header
l login processes
n # specify number of users per line for -q
p processes other than getty or users
q quick who
r run level
s short form of who (no time since last output or pid)
t time changes
T status of tty (+ writable, - not writable, ? hung)
u useful information
m information only about current terminal
am i information about current terminal (same as -m)
am I information about current terminal (same as -m)
