Answer 1

cut(1) was made expressly for this purpose:

cut -f 2-3 input.txt > output.txt

Phenomena

Answer 2

Cut is probably the best choice here, second to that is awk

awk -F"\t" '{print $2 "\t" $3}' input > out

Lecky

the file had 2 million rows so i guess cut was good...thank you for your help – Kerrykersey

awk comes in particularly handy when you want to change the order of columns. cut can't do that! – Breezy

Answer 3

expanding on the answer of carl-norum, using only tab as a delimiter, not all blanks:

cut -d$'\t' -f 2-3 input.txt > output.txt

don't put a space between d and $
