When you call your script with a filename -or something else- as an argument, you retrieve the first argument with "$1", the second with "$2", ...
This simple script above will give:
To read the file in '$1", you can simply cat "$1" but for the next requirement, write something with a loop that says:
From the example you wrote, you need to read every other line i is a variable that's incremented (i++) on every line read. i%2 returns 1 or 0, depending i is odd or even, basically, it returns 0 when i is 2; 4; 6; ...
And in sh/bash and many others scripting languages; zero means no errors.
No Errors: execute what's after the &&, so echo "$the_line"

Locale::Script(3pm) Perl Programmers Reference Guide Locale::Script(3pm)NAME
Locale::Script - standard codes for script identification
SYNOPSIS
use Locale::Script;
$script = code2script('phnx'); # 'Phoenician'
$code = script2code('Phoenician'); # 'Phnx'
$code = script2code('Phoenician',
LOCALE_CODE_NUMERIC); # 115
@codes = all_script_codes();
@scripts = all_script_names();
DESCRIPTION
The "Locale::Script" module provides access to standards codes used for identifying scripts, such as those defined in ISO 15924.
Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 15924
four-letter codes will be used.
SUPPORTED CODE SETS
There are several different code sets you can use for identifying scripts. A code set may be specified using either a name, or a constant
that is automatically exported by this module.
For example, the two are equivalent:
$script = code2script('phnx','alpha');
$script = code2script('phnx',LOCALE_SCRIPT_ALPHA);
The codesets currently supported are:
alpha, LOCALE_SCRIPT_ALPHA
This is a set of four-letter (capitalized) codes from ISO 15924 such as 'Phnx' for Phoenician. It also includes additions to this set
included in the IANA language registry.
The Zxxx, Zyyy, and Zzzz codes are not used.
This is the default code set.
num, LOCALE_SCRIPT_NUMERIC
This is a set of three-digit numeric codes from ISO 15924 such as 115 for Phoenician.
ROUTINES
code2script ( CODE [,CODESET] )
script2code ( NAME [,CODESET] )
script_code2code ( CODE ,CODESET ,CODESET2 )
all_script_codes ( [CODESET] )
all_script_names ( [CODESET] )
Locale::Script::rename_script ( CODE ,NEW_NAME [,CODESET] )
Locale::Script::add_script ( CODE ,NAME [,CODESET] )
Locale::Script::delete_script ( CODE [,CODESET] )
Locale::Script::add_script_alias ( NAME ,NEW_NAME )

Locale::Script::add_script_code_alias ( CODE ,NEW_CODE [,CODESET] )
Locale::Script::delete_script_code_alias ( CODE [,CODESET] )
These routines are all documented in the Locale::Codes::API man page.
