Shell脚本等待进程完成

Question

我有一个过程

"verifyEmail"
I run this in script as verifyEmail 0 1000

现在，在继续执行shell脚本中的下一条指令之前，我该如何等待此过程执行完毕？验证电子邮件运行需要60多分钟

我试过

while ! checkprocess "verifyEmail"; do   ##Checkprocess is a function which returns 0 or 1
sleep 60                                 ## based on process present or not
done 

Answer 1

如果您正常运行该过程，则无需执行任何操作。如果以异步方式运行它，则只需wait即可：

verifyEmail 0 1000
echo This will print after verifyEmail is done!

或

verifyEmail 0 1000 &
wait $!
echo This will print after verifyEmail is done!
