hi all

i am very new to perl so please forgive my stupidity

i have written the following program to verify some parameters of an interface of router .I have saved the file in same directory as the perl program(perl1.pl). when i do perl1.pl filename.txt i get the error that

Use of uninitialized value $second_file in open at C:\Users\Girish\Desktop\perl1 .pl line 10. No such file or directory at C:\Users\Girish\Desktop\perl1.pl line 10.

The program is:

use warnings;
$second_file=$ARGV[0];
$counter=0;
              open FH_SECOND,">",$second_file or die $!;            
          $line_second=<FH_SECOND>;

[download]

i solved the problem by using

open (FH_SECOND,"<",\$second_file) or die $!;

but can i use the declaration $line_second=<FH_SECOND>; to save the a line in the variable line_second
