原文件内容：
http://www.baidu.com/1.jpg

请高手帮忙
sed -r 's@//[^/]+@//192.168.1.100@' 1.txt
awk -F '/' '{print "--header=Host:"$3}' 2.txt

处理完后希望得到结果：

wget -s http://192.168.1.100/1.jpg --header="Host:www.baidu.com"

1. for check only
$ echo "http://www.baidu.com/1.jpg" | awk 'BEGIN{FS=OFS="/"}{h=$3;$3="192.168.1.100";cmd="wget -s "$0" --header=\"Host:"h"\"";print cmd}'
wget -s http://192.168.1.100/1.jpg --header="Host:www.baidu.com"

2. using system function to run command after check without issue
$ echo "http://www.baidu.com/1.jpg" | awk 'BEGIN{FS=OFS="/"}{h=$3;$3="192.168.1.100";cmd="wget -s "$0" --header=\"Host:"h"\"";print cmd;system(cmd)}'

1. awk -F/ '{a=$3;printf "wget -s "$1FS FS"192.168.1.100"FS$NF;print "--header=""\"Host:"a"\""}'
