How to extract string between IDs in shell

Question

I have a string that looks like this:

RG="@RG\tID:HS2000-1015_160.7\tDS:ADNI_1380^LP6005117-DNA_G04^ADNI_WGS\tLB:LP6005117-DNA_G04\tPL:illumina\tPU:HS2000-1015_160.7\tSM:ADNI_1380"

I want to extract everything after ID: and before first the \t

and get HS2000-1015_160.7 as a result. I would like a one-liner if possible.

code I tried:

echo ${RG} | grep -oP "(?<=ID:)[^"\t"]*"

which gives me HS2000-1015_160.7\

Why `grep`... `grep` is to filter __lines__, not to extract parts of text. — KamilCuk, Nov 09 '20 at 19:31
