Unrelated to that, you are closing the filehandle after reading just the first line, is that intentional? See
https://www.unix.com/shell-programmin...ents-perl.html -- are you on the same project as this other guy?
You are appending to file2 just after reading it, and if the close is wrong, you would apparently continue to read from it after appending; how exactly should this work, or rather, what are you trying to accomplish?
You probably mean
$arr_y[$num] rather than
@arr_y[$num]
Calling out to Perl via the shell from another Perl script is not very elegant, I guess there can be reasons why you want to do it that way, but refactoring
myscript.pl so that you can
require it from within Perl directly might make some things less awkward.

urifind
URIFIND(1p) User Contributed Perl Documentation URIFIND(1p)
NAME
urifind - find URIs in a document and dump them to STDOUT.
SYNOPSIS
$ urifind file
DESCRIPTION
urifind is a simple script that finds URIs in one or more files (using "URI::Find"), and outputs them to to STDOUT. That's it.
To find all the URIs in file1, use:
$ urifind file1
To find the URIs in multiple files, simply list them as arguments:
$ urifind file1 file2 file3
urifind will read from "STDIN" if no files are given or if a filename of "-" is specified:
$ wget http://www.boston.com/ -O - | urifind
When multiple files are listed, urifind prefixes each found URI with the file from which it came:
$ urifind file1 file2
file1: http://www.boston.com/index.html
file2: http://use.perl.org/
This can be turned on for single files with the "-p" ("prefix") switch:
$urifind -p file3
file1: http://fsck.com/rt/
It can also be turned off for multiple files with the "-n" ("no prefix") switch:
$ urifind -n file1 file2
http://www.boston.com/index.html
http://use.perl.org/
By default, URIs will be displayed in the order found; to sort them ascii-betically, use the "-s" ("sort") option. To reverse sort them,
use the "-r" ("reverse") flag ("-r" implies "-s").
$ urifind -s file1 file2
http://use.perl.org/
http://www.boston.com/index.html
mailto:webmaster@boston.com
$ urifind -r file1 file2
mailto:webmaster@boston.com
http://www.boston.com/index.html
http://use.perl.org/
Finally, urifind supports limiting the returned URIs by scheme or by arbitrary pattern, using the "-S" option (for schemes) and the "-P"
option. Both "-S" and "-P" can be specified multiple times:
$ urifind -S mailto file1
mailto:webmaster@boston.com
$ urifind -S mailto -S http file1
mailto:webmaster@boston.com
http://www.boston.com/index.html
"-P" takes an arbitrary Perl regex. It might need to be protected from the shell:
$ urifind -P 's?html?' file1
http://www.boston.com/index.html
$ urifind -P '.org' -S http file4
http://www.gnu.org/software/wget/wget.html
Add a "-d" to have urifind dump the refexen generated from "-S" and "-P" to "STDERR". "-D" does the same but exits immediately:
$ urifind -P '.org' -S http -D
$scheme = '^(http):'
@pats = ('^(http):', '.org')
To remove duplicates from the results, use the "-u" ("unique") switch.
OPTION SUMMARY
-s Sort results.
-r Reverse sort results (implies -s).
-u Return unique results only.
-n Don't include filename in output.
-p Include filename in output (0 by default, but 1 if multiple files are included on the command line).
-P $re
Print only lines matching regex '$re' (may be specified multiple times).
-S $scheme
Only this scheme (may be specified multiple times).
-h Help summary.
-v Display version and exit.
-d Dump compiled regexes for "-S" and "-P" to "STDERR".
-D Same as "-d", but exit after dumping.
