    Do you need to find all the names of a given gender using the grep command? Can you better give a sample input and output that you expect so that it would be much more clear? Commented Jan 8, 2015 at 20:59
  • you can not use “” quotes you have to use " Commented Jan 8, 2015 at 21:55
  • I see nothing wrong except the quotes and that you already know field 3 as that is what you search for. It could also miss trigger, for example I know someone whose name is male, see is female. Commented Jan 8, 2015 at 22:01
  • the code does not work, and if i purely use grep $gender Information.txt, it will return all 3 information as in the gender section, it contains "male" and fe"male" Commented Jan 9, 2015 at 1:09
  • @Ramesh how else would i be able to do it ? Commented Jan 9, 2015 at 14:09
