我在Linux上工作。我有两个程序，它们无限时间运行（也就是说，除非我杀死进程，否则不会停止）。我想先运行程序1，然后在20秒后运行程序2（两个程序都必须同时运行，因为其中一个读取另一个程序写入的文件）。目前，我通过手动跟踪时间来运行这2个程序。是否有自动化的方法？即是否有任何命令或可以编写任何程序来执行此操作。
prog1 &
sleep 20
prog2
使用 Shell：
方案1和计划;睡觉20;方案2
如果一个程序从另一个程序所输出的文件中读取数据，考虑使用管道将输出从一个程序传递给另一个程序的输入。
$> 程序1 | 程序2
我假设您可以控制这两个程序，并让它们写入标准输出并从标准输入读取。
