Question

How can I get text using grep command txt that seats between two strings?

for example:

<--string 1-->
the text i need
<--string 2-->

the “the text i need” between the two tags is dynamic, therefor i need a command that will output text from “<–string 1–>” to “<–string 2–>”

Supposing “the text I need” is just one line, you should check that both string1 and string2 appear (Alex’s solution only checks one thing).

A better solution would be:

grep -A 2 "string 1" $file | tail -2 | grep -B 1 "string 2" | head -1
