Bash如何按顺序(非并行)运行多个wget并删除wget文件以进行speedtest

我有一个文件下载wget列表,想看看下载速度。我只想运行大约10秒,然后打印出结果什么是下载速度。 我有20个不同的服务器文件要测试。我的目标是在这10秒钟内查看kb/s的下载速度。

> wget https://lg-lis.fdcservers.net/100MBtest.zip

100MBtest.zip                      0%[                                                         ] 679.66K   174KB/s    eta 9m 26s ^C

这是我的bash文件

#!/bin/bash

function speedtest() {

    local key=$1
    local url=$2

    timeout 10 wget $url
    echo -e "\033[40;32;1m$key is completed.\033[0m"

 
}
speedtest "Lisbon" "https://lg-lis.fdcservers.net/100MBtest.zip"
speedtest "London" "https://lg-lon.fdcservers.net/100MBtest.zip"
speedtest "Madrid" "https://lg-mad.fdcservers.net/100MBtest.zip"
speedtest "Paris" "https://lg-par2.fdcservers.net/100MBtest.zip"

> ./wget_speedtest.sh                                                                                       


Redirecting output to ‘wget-log’.

Lisbon is completed.

Redirecting output to ‘wget-log.1’.
London is completed.

Redirecting output to ‘wget-log.2’.
Madrid is completed.

Redirecting output to ‘wget-log.3’.
Paris is completed.

上面的输出,我看不到下载速度。

,下面是我每次手动运行4个命令,我希望通过运行 一次狂欢 然后运行wget 删除下载的文件 . 例如100MBtest.zip

我尝试将命令和run结合在一起,它同时运行所有4个命令,并且只有1个输出。
