如何在bash脚本中包含nohup?

本文介绍了如何在bash脚本中包含nohup?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我有一个名为 mandacalc 的大型脚本，该脚本始终与 nohup 命令一起运行.如果我从命令行以以下方式调用它:

I have a large script called mandacalc which I want to always run with the nohup command. If I call it from the command line as:

nohup mandacalc &

一切迅速进行.但是，如果我尝试在命令中包含 nohup ，那么我不必每次执行时都键入它，就会收到错误消息.

everything runs swiftly. But, if I try to include nohup inside my command, so I don't need to type it everytime I execute it, I get an error message.

到目前为止，我尝试了以下选项:

So far I tried these options:

nohup ( command1 .... commandn exit 0 )

还有:

nohup bash -c " command1 .... commandn exit 0 " # and also with single quotes.

到目前为止，我只收到错误消息，抱怨有关 nohup 命令的实现或脚本中使用的其他引号.

So far I only get error messages complaining about the implementation of the nohup command, or about other quotes used inside the script.

欢呼.

推荐答案

尝试将其放在脚本的开头:

Try putting this at the beginning of your script:

#!/bin/bash case "$1" in -d|--daemon) $0 < /dev/null &> /dev/null & disown exit 0 ;; *) ;; esac # do stuff here

如果现在以--daemon作为参数启动脚本，它将重新启动与当前shell分离的脚本.

If you now start your script with --daemon as an argument, it will restart itself detached from your current shell.

您仍然可以通过不使用此选项启动脚本来在前台"运行脚本.

You can still run your script "in the foreground" by starting it without this option.
