如何在Linux中使用nohup将进程作为后台进程运行? [英] How can I use nohup to run process as a background process in linux?

问题描述

我使用此命令来运行我的工作.

I use this command to run my work.

(time bash executeScript 1 input fileOutput $> scrOutput) &> timeUse.txt

同时，我使用了1个进程来运行此工作.我必须更改每次运行的进程数.每次都要花费很长时间才能完成.然后我想将其作为后台进程运行.

While, 1 is a number of process that I use to run this work. I have to change the number of process for each run. At each time it use long time to complete. Then I want to run it as background process.

我该怎么办?

我尝试过:

nohup ((time bash executeScript 1 input fileOutput $> scrOutput) &> timeUse.txt)

但这是行不通的.

推荐答案

通常，我使用nohup CMD &运行nohup后台进程.但是，当命令采用nohup不会接受的形式时，我将通过bash -c "..."运行它.

In general, I use nohup CMD & to run a nohup background process. However, when the command is in a form that nohup won't accept then I run it through bash -c "...".

例如:

nohup bash -c "(time ./script arg1 arg2 > script.out) &> time_n_err.out" &

脚本中的

stdout被写入script.out，而stderr和time的输出进入time_n_err.out.

stdout from the script gets written to script.out, while stderr and the output of time goes into time_n_err.out.

因此，在您的情况下:

nohup bash -c "(time bash executeScript 1 input fileOutput > scrOutput) &> timeUse.txt" &
