叉状指挥燮preSS通知被杀 [英] Suppress Notice of Forked Command Being Killed

问题描述

让我们假设我有一个bash脚本（ foo.sh ），在一个非常简单的形式，如下所示：

Let's suppose I have a bash script (foo.sh) that in a very simplified form, looks like the following:

echo "hello"
sleep 100 &
ps ax | grep sleep | grep -v grep | awk '{ print $1 } ' | xargs kill -9
echo "bye"

第三行模仿 pkill的，我不默认情况下，在Mac OS X有，但你可以把它当做一样 pkill的。然而，当我运行此脚本，我得到以下的输出：

The third line imitates pkill, which I don't have by default on Mac OS X, but you can think of it as the same as pkill. However, when I run this script, I get the following output:

hello
foo: line 4: 54851 Killed                  sleep 100
bye

我如何燮preSS中间的线，让所有我看到的是你好和再见？

推荐答案

如何不认？这主要适用于我的击在Linux上。

How about disown? This mostly works for me on Bash on Linux.

echo "hello"
sleep 100 &
disown
ps ax | grep sleep | grep -v grep | awk '{ print $1 } ' | xargs kill -9
echo "bye"
