Sed gurus: Say I have this input in in.txt:
The quick brown fox
jumps over the lazy
dog
The quick brown fox
jumps https://example.com/1[Example1] over the lazy
dog
I want the output to look like this:
The quick brown fox
jumps over the lazy
dog
The quick brown fox
jumps https://example.com/1[Example1] over the lazy
dog
So I want all URLs inside paragraphs to be copied to right before the paragraph with two line-breaks after it. Any takers? Other tool are ok too, if they're available on a typical slimmed linux machine.
