Bash文件:并行运行进程，并在进程结束时停止 [英] Bash files: run process in parallel and stop when one is over

问题描述

我想从bash文件中并行启动两个C代码，第二个在第一个完成时停止.等待指令会导致两个进程都停止，这不是我想要做的.感谢您的任何建议.

I would like to start two C codes from a bash file in parallel and the second one stops when the first one has finished. The instruction wait expects both processes to stop which is not what I would like to do. Thanks for any suggestion.

推荐答案

GNU并行可以做这种工作.检查终止部分，它可以根据退出关闭其余进程代码(成功或失败:

GNU parallel can do this kind of job. Check termination section, it can shutdown down remaining processes based on the exit code (either success or failure:

parallel -j2 --halt now,success=1 ::: 'cmd1 args' 'cmd2 args'

其中一个作业成功完成时，它将向其他作业发送TERM信号(如果作业未终止，则使用KILL信号强制执行该操作).

When one of the job finishes successfully, it will send TERM signal to the other jobs (if jobs are not terminated it forces using KILL signal).
