这似乎是一个愚蠢的问题,但我一直无法找到明确的答案。
这个网站 http://www.linfo.org/ps.html表明破折号是可选的
ps aux
然而,ps aux
有效但是ps -aux
引发错误no user named 'x'
。有什么想法可能是这里的问题吗?运行 Mac 10.8.2。谢谢
man ps
会给你这个:
The biggest change is in the interpretation of the -u option, which now
displays processes belonging to the specified username(s). Thus, "ps
-aux" will fail (unless you want to know about user "x"). As a conve-
nience, however, "ps aux" still works as it did in Tiger.
