perl linenum script
im working a a perl script for a class and i need to call a file and print it out with line numbers.

i need help with this line with what to put in the capitalized words

Code:
SYNTAX ($LINEEQUALITY OPERATOR<MY_FILE>){

also should i replace MY_FILE with a different syntax or will that work?

here is my entire script

Code:
#!/usr/bin/perl -w
unless (scalar(@ARGV) == 2){
   print "error: incorrect number of arguments",
   "\n",
   "usage: linenum.pl [filename]",
   "\n";
      exit 1;
}

# Open function used with  filehandle and input file.
open(MY_FILE, "$ARGV[1]") or die
   "error: argument must be a file\n",
   "usage: linenum.pl [filename]\n$!\n";

# Check if file is a directory
if (-d "$ARGV[1]"){
   print "error: argument must be a file",
   "\n",
   "usage: linenum.pl [filename]\n";
   exit 1;
}

$COUNTER=1;  # Used for printing line numbers









# Loop and write lines from file
SYNTAX ($LINEEQUALITY OPERATOR<MY_FILE>){
   # Adds leading zeros for numbers 1 digit long
   if ($COUNTER<10){
      print "000";
   }
   # Adds leading zeros for numbers 2 digits long
   if (($COUNTER>9) && ($COUNTER<100)){
      print "00";
   }
   # Adds leading zeros for numbers 3 digits long
   if (($COUNTER>99) && ($COUNTER<1000)){
   print "0";
   }
   # Prints line number and line
   print "$COUNTER: $LINE";
   $COUNTER+=1;
}
exit 1;
