我的 url (http://myhost.com/getuser/Default.aspx?username= b772643) 总是返回以下信息行：
John, Thomas;[email protected]
I wish to read this line using a shell or bash script without wget/lynx. I'm in a situation where I cannot use any other utility, the perl language etc.
我希望使用没有 wget/lynx 的 shell 或 bash 脚本来阅读这一行。我处于无法使用任何其他实用程序、perl 语言等的情况。

Curl or wget are obviously better for the job but for the record bash and Unix standard commands (cat & printf) can do the job.
curl 或 wget 显然更适合这项工作，但对于记录 bash 和 Unix 标准命令（cat & printf）可以完成这项工作。
ksh introduced shell network internal handling and this has been adopted by bash.
ksh 引入了 shell 网络内部处理，这已被 bash 采用。
#!/bin/bash
exec 5<> /dev/tcp/myhost.com/80
cat <&5 &
printf "GET /getuser/Default.aspx?username=b772643 HTTP/1.0\r\n\r\n" >&5

One liner:
一个班轮：
(echo 'GET /getuser/Default.aspx?username=b772643' > /dev/tcp/myhost.com/80);

curl "http://myhost.com/getuser/Default.aspx?username=b772643"
curl "http://myhost.com/getuser/Default.aspx?username=b772643"| sed 's/\(.*\);\(.*\)/ /' | while read email name; do echo =$email=$name=; done
