nohup命令的全称为"no hang up",该命令可以将程序以忽略挂起信号的方式运行起来,被运行的程序的输出信息将不会显示到终端。 无论是否将 nohup 命令的输出重定向到终端,输出都将附加到当前目录的 nohup.out 文件中。
Lastly I hope the steps from the article to understand the difference between tty and pts i.e. tty vs pts on Linux was helpful. So, let me know your suggestions and feedback using the comment section.
nohup bin/ config/ > /dev/null 2>&1 & 查了一下: 在命令最后加上&符号,表示让这个进程到后台去执行,这样立刻返回到提示符状态,我们可以接着做下面的事。如:command &。
And I run it through "nohup": nohup & But by watching "top", the command itself isn't executed! (Or it shows up and quickly disappears constantly!) And the output file shows multiple times: [nohup.out] bash: no job control in this shell. The only processes that I can see running are: /bin/bash bash command

This splits VS Code into a "client-server" architecture, with the client (the VS Code user interface) running on your Windows operating system and the server (your code, Git, plugins, etc) running "remotely" on your WSL Linux distribution.

May 26, 2017 · echo pyperformance run --python=python3 -o result.json | nohup sudo classic & We used this tricky command just to allow the test to run in the background without an active ssh connection since it takes time and to avoid any issues due to a lost ssh connection (the test would also be stopped).
It is also extremely modular so you can easily include or exclude commands (or features) at compile time. This makes it easy to customize your embedded systems. To create a working system, just add some device nodes in /dev, a few configuration files in /etc, and a Linux kernel.
I quite confuse when seeing that you put setsid and nohup together. We can run setsid with -f option so it will be always running in a new process. If you don't want nohup still print out to the terminal, use your second way (can remove the part setsid away too). Anything that I don't know? – Tuananhcwrs Oct 24 at 17:08
大多数Linux系统,这个参数默认关闭(off)。 因此,session 退出的时候,不会把SIGHUP信号发给"后台任务"。 nohup命令对server.js进程做了三件事。 阻止SIGHUP信号发到这个进程。 关闭标准输入。 该进程不再能够接收任何输入,即使运行在前台。
My problem is that even though nohup makes my command run in the background, it prints out something like this to my terminal: [1] 27918. Edit: It seems that (setsid yourcommand &) is the best combination, since it detaches from the tty and works equally in interactive and script modes.
I agree generally with Christopher P's answer (and voted it up), but to speak a little more about the logging option here. An initial scan of the examples you have given would suggest that you would end up with better logging options with the nohup version that the --fork version. If instead you started with
I got around this by calling the system 'at' command on Linux. "at run something now". and you have to set atrun -s in a crontab file (to run every minute) to insure that things get kicked off quickly even if there is a heavy load on the machine. If you're the only one running batch jobs on a linux box, this works.

nohup与&启动的程序, 在终端还未关闭时,完全不像传统的守护进程,因为其不是会话首进程且持有终端,只是其忽略了SIGHUP信号. 从nohup源码就可以看到,其实nohup只做了3件事情. dofile函数将输出重定向到nohup.out文件

setsid. 上面讲的忽略SIGHUP信号,那如果我们给它(任务)换个爹(父进程)呢? 上文提到过nohup成功后的提示:nohup: ignoring input and appending output to 'nohup.out' 默认情况下nohup的作业的所有输出会被重定向到 nohup.out这个文件中,当然,你也可以指定输出:
nohup. 程序加上nohup & ,即 nohup ./hello &, 忽略hangup信号,防止shell关闭时程序停掉。 4. setsid. 程序加上setsid ,即 setsid ./hello, 将命令放入到一个作业队列中,可以用命令jobs查看
nohup bash -c 'apt update; export DEBIAN_FRONTEND=noninteractive; apt-get -y --only-upgrade install hive; hello restartminer; screen -S agent -X quit; agent-screen' > /tmp/nohup.log 2>&1 &. Pretty long line, but paste it in Linux Execute and run.
常在 linux 下玩耍的开发者肯定会经常遇到需要对进程调度的情况,在 windows 中点击 最小化 去干别的就 OK 了,那么在 linux 下怎么办呢。 但是 setsid 并没有为进程分配一个输出终端,所以进程还是会输出到当前终端上。
BusyBox is a multi-call binary. A multi-call binary is an executable program that performs the same job as more than one utility program. That means there is just a single BusyBox binary, but that single binary acts like a large number of utilities.

$ nohup program & 실행을 하고나면, 명령어를 실행한 경로에 nohup.out이라는 파일이 생기며, program 이라는 프로세스가 뿜어내는 로그들을 찍게 되는데, 이후에 해당 프로세스를 죽이거나 재실행 하기 위해서는, 프로세스를 일일히 뒤져서 pid를 알아내서 죽여야 한다.
