Like RudiC mentioned, x=$1 Assigns the value of the first parameter with which the script is called to variable x
After this there are 5 iterations that add a number to variable x
So in the end variable x will contain the sum of 6 numbers.
So if you call the script like this:
Then the outcome is 43
renders 44

Also: let is an old, non-standard way of doing this. It is better to use portable shell arithmetic. So instead of
use
--
In bash/ksh/zsh you can also use:

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. The ones currently supported are:
alpha
This is a set of four-letter (capitalized) codes from ISO 15924 such as 'Phnx' for Phoenician.
This code set is identified with the symbol "LOCALE_SCRIPT_ALPHA".
The Zxxx, Zyyy, and Zzzz codes are not used.
This is the default code set.
numeric
This is a set of three-digit numeric codes from ISO 15924 such as 115 for Phoenician.
This code set is identified with the symbol "LOCALE_SCRIPT_NUMERIC".
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::delete_script_alias ( NAME )
Locale::Script::rename_script_code ( CODE ,NEW_CODE [,CODESET] )
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 man page.
