“谁"变量中的输出丢失其格式 [英] "whois" output in a variable loses its formatting

问题描述

我一直在浏览我写的旧脚本，该脚本将whois输出写入文件，然后将grep写入该文件中的某些信息.

I have been looking through an old script I wrote which writes whois output to a file and then grep for certain info in that file.

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.

I thought maybe I should change this and save the whois output as a variable - but when I do that, the output loses its formatting.

me@server:~$ echo $info_domain

所需的输出:

me@server:~$ whois example.com

如何将whois输出保存到变量而不丢失其格式?

How can I save whois output to a variable without it losing its formatting?

推荐答案

这可能是引用问题.代替

This might be a quoting issue. Instead of

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其为单词拆分.

so that the format is preserved. Technically, the double quotes prevent what shell gurus call word splitting.
