Specify NR if you want to capture output from selected rows   awk  NR  1 print  1    etc  release   An alternative  ugly  way of achieving the same would be   awk   print  1  exit     An efficient way of getting the first string from a specific line  say line 42  in the output would be   awk  NR  42 print  1  exit
