Linux: How can i grep text from string to string

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-->"

This might work for you:

grep -A2 "<--string 1-->" file | grep -v "<--string 1-->\|<--string 2-->"

or

grep -A1 "<--string 1-->" file | grep -v "<--string 1-->"

or in a single process:

sed '/<--string 1-->/,/<--string 2-->/!d;//d' file

or:

awk '/<--string 2-->/{p=0};p;/<--string 1-->/{p=1}' file
