I have to read a text file using shell scrip from value abc to pqr and store that data to new.txt

Note: text file contain multiple block of value abc to pqr. So I have to read all block one by one.

In linux I am searching a particular value from text file and I am getting text. i.e above and below 20 lines from the searched value. I am storing that data in new text file output.txt

Command:

Str=$(grep -i -B 20 -A 20 "searching_value" test.txt)
echo "${str}" >> output.txt

My best guess is `awk`. – Dominique Mar 09 '23 at 07:53

Try `sed -n '/abc/,/pqr/p' test.txt` to filter all blocks with one command. – Wiimm Mar 09 '23 at 08:13
Maybe remove the `sh` tag and replace with `awk` if `awk` is acceptable to you. – Mark Setchell Mar 09 '23 at 09:11
Please [edit] your question and add some example input and the expected output, formatted as code blocks. I suggest to remove one/some of your tags and add `unix-text-processing`. – Bodo Mar 09 '23 at 18:08
