Question

如果我写ps -ef，则返回当前运行的所有进程。如果我键入ps -ef | grep xxx，则它返回使用子字符串xxx运行的所有进程。但ps -ef | grep xxx也是当前流程，因此它也会在列表中返回grep xxx。

我只想从列表中删除grep xxx。

任何人都可以帮我这个。
感谢

Answer 1

尝试这样做：

pgrep -fl xxx

另一种解决方案

ps -ef | grep '[x]xx'

这是一个避免重复的简单正则表达技巧

Answer 2

而不是说

ps -ef | grep xxx

说

ps -ef | grep [x]xx

并且您不会在输出中看到grep xxx。（基本上将所需单词的第一个字符作为字符类[]。）

活动进程除当前进程外运行
