作为普通用户，当我运行某些命令（例如 ps\netstat）时，终端提示我：
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)
我知道可以将 STDERR 重定向到 /dev/null 以删除此提示。但我想知道是否有任何方法可以删除它，例如编辑一些配置文件？

非常感谢。
解决了：
下载 procps 源代码并重建它，提示消失了。

您在 EL5 上运行对吗？我这里有一个 EL5 盒子，它给了我：
$ ps -V
procps version 3.2.7
没有提示。包/bin/ps中procps没有配置文件。
此外：您的机器上发生了一些奇怪的事情。我没有时间真正深入研究这个问题（所以也许这是您环境中的预期行为），但是我们的 strace 输出中所有与 Perl 相关的东西是怎么回事？ps与 Perl 无关，那么为什么我在您的 strace 输出中看到各种与 Perl 相关的东西（ActivePerl、pdk-deploy 等）？要么是它被污染了，被您 .bashrc 中的一些奇怪的构造所污染，要么您有pset al 的别名，把事情搞糟了，要么是有人在捉弄您。
