我有2台suse-11机器都有相同的内核版本。
Linux版本2.6.32.59-0.7-default(geeko @ buildhost)(gcc版本 4.3.4 [gcc-4_3-branch revision 152973](SUSE Linux))#1 SMP 2012-07-13 15:50:56 +0200
但是在命令下面的一台机器上工作
ps -u test-o'%U%p%P%c'
但在其他方面会出现如下错误
ERROR: Garbage option.
********* simple selection ********* ********* selection by list *********
-A all processes -C by command name

真的无法弄清楚这里有什么问题,任何人都可以告诉我可能出现的问题吗?
编辑:两者中的ps都给出了 / bin中/ PS答案 0 :(得分:-1)
我检查了两个ps命令的md5sum,它有所不同。所以我怀疑有人可能在没有通知的情况下更换了这个箱子。从正确的源复制ps命令并解决问题
