Linux - Shell script run curl command in parallel

Question

I would like to create linux shell script to run CURL command in parallel

For example: I have three command like

1. curl -s http://localhost/process.php?id=1
2. curl -s http://localhost/process.php?id=2
3. curl -s http://localhost/process.php?id=3

I want to call above three command simultaneously.

Any help is appreciated.

Answer 1

I think a bash script like:

#!/bin/bash

curl -s http://localhost/process.php?id=1 &
curl -s http://localhost/process.php?id=2 &
curl -s http://localhost/process.php?id=3 &

However, this is starting all tasks as background processes. Don't know how crucial simultaneous starting of the process is.

Answer 2

我想你可以在一行中的curl命令之间使用＆，如下所示：

curl -s http://localhost/process.php?id=1 & curl -s http://localhost/process.php?id=2 & curl -s http://localhost/process.php?id=3
