我想将从对含水层的背景应用中产生的产出转用于/dev/null。

我正在使用打印文本编辑,并印刷了我想转至/dev/null的终端上的所有短信。

如何做到这一点?

最佳回答

您:

yourcommand  > /dev/null 2>&1

If it should run in the Background add an &

yourcommand > /dev/null 2>&1 &

<代码>>/dev/null 2>&1 系指向<代码>stdout至/dev/nullstderrstdout的地方 当时各点

如果你想要<条码>stderr,就出现在ole上,只有<条码>stdout。 ∗ 待印发。 您可以使用:

yourcommand 2>&1 > /dev/null

在此情况下,stderr被转至stdout(例如,您的专才)和 以下。 原来的<代码>stdout 改为/dev/null

如果方案不能终止,可使用:

nohup yourcommand &

无任何参数,所有生产用地都是 no。 页: 1

问题回答

这两者还将调整:

yourcommand  &> /dev/null

yourcommand  >& /dev/null

虽然《篮子手册》说首部是首选的。
