我一直在浏览我编写的旧脚本，该脚本将whois输出写入文件，然后在该文件中使用grep读取某些信息。
我想也许应该更改此设置并将whois输出保存为变量-但是当我这样做时，输出将失去其格式。
me@server:~$ echo $info_domain
Whois Server Version 2.0 Domain names in the .com and .net domains
can now be registered with many different
competing registrars. Go to http://www.internic.net for detailed
information. Server Name: EXAMPLE.COM.AU Registrar: ENETICA PTY LTD
Whois Server: whois.enetica.com.au Referral URL:

whois.godaddy.com Referral URL: http://registrar.godaddy.com Server

所需的输出：
me@server:~$ whois example.com
Whois Server Version 2.0

如何whois在不丢失其格式的情况下将输出保存到变量？
这可能是一个报价问题。代替
echo $info_domain
尝试
echo "$info_domain"
以便保留格式。从技术上讲，双引号可以防止外壳专家称单词分裂。
