I need to cut the both 0 0 from A and G but I cant seem to do it without cutting all zeros from the text which is not what I want, just those four zeros, how would I do this?

  • probably has flaws but sed 's/ 0//g' input or sed 's/0 0//g' input <=SE removed the extra spaces in there. Commented Feb 11, 2018 at 18:30

    What's the rule? "Remove columns 2 and 3 if they exist?" or " ... if they exist and are 0"? or "if they exist on lines where column 1 is an A or G"? Commented Feb 11, 2018 at 18:31
  • @cargoboom: Be wary of using my first suggestion. if any of your numbers start with a 0 it will give unwanted results. For example if you had: C 07.621 it would cut it to C 7.621 Commented Feb 11, 2018 at 18:39

    Rather than cutting the fields you don't want, consider printing the fields that you do e.g. cut -d ' ' -f1,2 file or awk '{print $1, $2}' file Commented Feb 11, 2018 at 19:43

Assuming input is space delimited:

cut -d' ' -f 1-2 input

(This answer is the same as steeldriver's prior comment...)
