I have a file with many rows as below. I just want to extract columns 2,3,5,6; but the third column without the 'chr' prefix:
585 ENST00000417324 chr1 - 34553 36081 36081 36081 3
ENST00000417324 1 34553 36081
I would use awk as the task is very simple, but I don't know how to get rid of the 'chr' prefix.
