Your code has same problem as radoulov's, that's why I update radoulov's code, and paste here.

Ok, Slightly modified for handling it..

Code:
 
perl -ne 'chomp ; push(@a,"$_ at line  $."); END{ print  "",(sort { $a <=> $b } @a)[0]; }' file

OK,
rdcwayx is right, I overlooked the fact that the minimum value was needed as well:


Code:
 awk 'END { 
  print v, "on line", nr
  }
{
  NR == 1 && min = $1 
  if ($1 <= min) {
    v = $1; nr = NR
    }
  }' infile
