在shell中打印具有多行值的变量? [英] Print a variable with multi-line value in shell?

问题描述

在Bash(或其他Shell)中，如何打印具有多行值的环境变量?

In Bash (or other shells) how can I print an environment variable which has a multi-line value?

text='line1
line2'

我知道一个简单的常规echo $text不会开箱即用. 一些$ IFS调整会有所帮助吗?

I know a simple usual echo $text won't work out of the box. Would some $IFS tweak help?

我当前的解决方法是类似于ruby -e 'print ENV["text"]'. 可以在纯外壳中完成吗?我想知道env命令是​​否采用未解析的var名称，但似乎没有.

My current workaround is something like ruby -e 'print ENV["text"]'. Can this be done in pure shell? I was wondering if env command would take an unresolved var name but it does not seem to.

推荐答案

与以往一样的解决方案.

Same solution as always.

echo "$text"
