ps命令-o选项提供“错误:垃圾选项”

Question

我有2台suse-11机器，它们都有相同的内核版本.

Linux2.6.32.59-0.7-默认(geeko@buildhost) (gcc版本4.3.4 3-branch revision 152973 ) #1 SMP 2012-07-13 15:50:56 +0200

但是在一台命令下的机器中

ps -u试验-O '%U %p %P %c‘

但在另一个错误中，如下所示

ERROR: Garbage option.
********* simple selection *********  ********* selection by list *********
-A all processes                      -C by command name

真的搞不懂这里有什么问题，有谁能告诉我什么是不对的呢？

编辑:哪个ps在两者中给出/bin/ps

Answer 1

我检查了两个ps命令的md5sum，这是不同的。所以我怀疑有人可能在没有通知的情况下就把这个垃圾箱换了。从正确的源复制ps命令并解决问题
