How to store and echo multiple lines elegantly in bash?
提问by EmpireJones
I'm trying to capture a block of text into a variable, with newlines maintained, then echo it.
我试图将一段文本捕获到一个变量中,并保留换行符,然后回显它。
However, the newlines don't seemed to be maintained when I am either capturing the text or displaying it.
