在Linux中重新启动文件更改过程 [英] Restart process on file change in Linux

问题描述

是否存在一个简单的解决方案(通过大多数发行版提供的util使用常见的shell utils，或一些简单的python/...脚本)在某些文件更改时重新启动进程?

Is there a simple solution (using common shell utils, via a util provided by most distributions, or some simple python/... script) to restart a process when some files change?

像watch -cmd "./the_process -arg" deps/*那样简单地调用sth会很好.

It would be nice to simply call sth like watch -cmd "./the_process -arg" deps/*.

更新: 一个简单的shell脚本以及建议的inotify-tools(不错！)可以满足我的需要(适用于不带参数的命令):

Update: A simple shell script together with the proposed inotify-tools (nice!) fit my needs (works for commands w/o arguments):

#!/bin/sh
while true; do
  $@ &
  PID=$!
  inotifywait $1
  kill $PID
done

推荐答案

是的，您可以使用 inotifywait将在检测到事件时退出.传递选项-r来递归监视目录.例如:inotifywait -r mydirectory.

inotifywait will exit upon detecting an event. Pass option -r to watch directories recursively. Example: inotifywait -r mydirectory.

您也可以指定要监视的事件，而不是监视所有事件.要仅等待文件或目录内容更改，请使用选项-e modify.

You can also specify the event to watch for instead of watching all events. To wait only for file or directory content changes use option -e modify.
