更优雅的“ps aux |” grep -v grep“ [英] More elegant "ps aux | grep -v grep"

问题描述

当我检查进程列表并grep出那些对我有意思的内容时，结果中也包含 grep 本身。例如，要列出终端：

  $ ps aux | grep终端
用户2064 0.0 0.6 181452 26460？ Sl Feb13 5:41 gnome-terminal --working-directory = .. 
 user 2979 0.0 0.0 4192 796 pts / 3 S + 11:07 0:00 grep --color = auto terminal 
  

通常我使用 ps aux | grep something | grep -v grep 来摆脱最后一项...但它不是优雅的：）

你是否有更优雅的黑客来解决这个问题（除了把所有的命令包装到一个单独的脚本中，这也是一件坏事）

解决方案

通常的技术是这样的：

  ps aux | egrep'[t] erminal'
  

这将匹配包含 code>，其中 egrep'[t] erminal'不！它也适用于Unix的 许多 。

When I check list of processes and 'grep' out those that are interesting for me, the grep itself is also included in the results. For example, to list terminals:

$ ps aux  | grep terminal
user  2064  0.0  0.6 181452 26460 ?        Sl   Feb13   5:41 gnome-terminal --working-directory=..
user  2979  0.0  0.0   4192   796 pts/3    S+   11:07   0:00 grep --color=auto terminal

Normally I use ps aux | grep something | grep -v grep to get rid of the last entry... but it is not elegant :)

Do you have a more elegant hack to solve this issue (apart of wrapping all the command into a separate script, which is also not bad)

解决方案

The usual technique is this:

ps aux | egrep '[t]erminal'

This will match lines containing terminal, which egrep '[t]erminal' does not! It also works on many flavours of Unix.
