I'm trying to parse values present in rows in a column to two parts using a specific string as parser. But, unable to parse it, most of online available examples uses delimiter for their examples, but I want a small string (two letters) to act as parser. Is it recommended to do it using awk & sed ? Example:
Col1

BOT-rs104894363
BOT-rs10774624
BOT-rs111647200

rs6837180
rs6837215
rs6837250
seq-rs794727444.1
seq-rs794727773.1
seq-rs794728252.1
seq-rs794728252.2
Here, I want to parse only rsID (rs followed with numericID) to be parsed separately from the prefixes.

grep -P 'rs\d+\.?\d+?' test.txt -o
where test.txt is the file containing the ids you have mentioned above
output

How to define col here, If I wish to give col ID = 1 ? And also I don't need integers present after decimal ? Like in some rs'ids I have .1, .2 .. Don't need them. Can we mention these two things in your script ?
Can you paste an example how should your result look like?
$grep -Po '(?<=^|-)rs\w*' test.txt
rs10136766
rs104894363
rs10774624
rs111647200
rs117306900
rs117306950
rs117306954

rs6837250
rs794727444
rs794727773
rs794728252
rs794728252
try this
grep -P 'rs\d+' test.txt -o
I have rsid's in col2. Where to specify col name in this script ?
I don't want to fetch rsid's to another file. I want to print the o/p in the same col. Where rs not found that row will not be printed or it will be omitted.

Maybe move to answer?
Guessing from
.1,.2suffixes, is this an output from an R script?
