Alternatively, if the characters between "ROI_" and "_AND" always comprise of digit(s), then you could take advantage of that in your sed command.

I was thinking of getting the solution using sed only, I could have used "AND_mod" in my sed statement but that won't be generic one. You are correct that between ROI and AND there will be digits , but it could be "ROI_2_3_AND_mod_AND_name", in that case I would want 2_3 as an answer. Thanks for your effort anyways.

I thought of this solution but it is not generic enough for me. Infact I did this to get temporary solution.
Thanks for your effort though.

I guess I didn't explain in detail. It could be "ROI_2_3_4_AND_mod_AND_name". I think your solution would give me "4" but instead I want:2_3_4 , that is anything between ROI_ and _AND (The first AND).
Thanks for your effort.
