What is the equivalent of NR (awk) in perl?

Hello,

I searched online; it seems that perl use $NR as NR in awk; however it does not work for me. For example, how to re-write the following awk using perl:

Code:
awk '{ print NR}' inputfile

---------- Post updated at 01:55 PM ---------- Previous update was at 12:49 PM ----------

I found following perl command will work the same as awk:

Code:
perl -MEnglish -lane 'print $NR' inputfile

However, I am wondering, if i am writing a perl script, is there a simple way to denote NR (number of record)?

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
