Eventhough BASH is my currently my most favorite language, for (possibly) 'real' applications, specialy when it comes with numbers handling as in do math, i would choose something else... like python.
AFAIK, awk is no programing language, but a 'streaming/parsing' tool.
(simple said)
Me quite confused by your syntax.
There is:
Code:
init 50 = 0 1 4 20
purchase 38 = 2 0 0 0
But there is also
Code:
change 0 0 0 1 = 5 1 1 0
change 0 1 = 5
To me this looks like you want to do 2 things at once, while the programing itself, would might be logical, think of what the cashier must do to enter this syntax!
Usualy the chashiers just type in the amount of cash the items costs, and the 'added up' amount the buyer pays. They do NOT count every single piece of cash, and enter 2x5$ 1x10$, 3x20$, etc...
They simply type: 78$ cost -> 80$ paid, returns -> 2$ returns.
I agree, it WOULD be a nice-to-have feature, but for the cashier its very unpractical to count the cash (not the value) each and every time, all day long, when there are 50 people at the register waiting..
Get my point?
In the end, a cash register is more like a big calculator, sure, it contains cash, but in the end, it just sums up the values, and not the counts of cash-items.
That is done at the evenings, manualy. (unless they have a cash counter- another device)
So my only suggestion is to make the syntax simpler.
Change only: VALUE
Pay: COST GIVEN
-> Returns: return/change
So you would only need to catch 2 arguments.
However, if you plan to do this as a 'backend', as in you then could make the GUI having fields to enter the amount of every single cash-item, which then, if there is something within the text field, pass this value as optional value to the script.
As in:
Pay: -twenty 1 -five 1 COST(22) paid(sumy up the textfield=25)
Returns: Return 3
(since there were optionas passed, show) Flow: +10 +5 -2 -1
While the italic text would be generated by the GUI, since there were only 2 (optional) textfield filled)
Hope this helps
EDIT:
Alternativly, you could expect:
Pay: COST / GIVEN
And simply split up the GIVEN to a possiblity of cash combinations.

hi,
Somebody have or known where i can find a perl small perl program to change the password.
The point: First it verify is the user exist, checking the old typed password and replace it with new. The passwords must be encoded.

Is there any system call or library available for this?:confused:

Locale::Codes::LangVar(3pm) Perl Programmers Reference Guide Locale::Codes::LangVar(3pm)NAME
Locale::Codes::LangVar - standard codes for language variation identification
SYNOPSIS
use Locale::Codes::LangVar;
$lvar = code2langvar('acm'); # $lvar gets 'Mesopotamian Arabic'
$code = langvar2code('Mesopotamian Arabic'); # $code gets 'acm'
@codes = all_langvar_codes();
@names = all_langvar_names();
DESCRIPTION
The "Locale::Codes::LangVar" module provides access to standard codes used for identifying language variations, such as those as defined in
the IANA language registry.
Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default IANA language
registry codes will be used.
SUPPORTED CODE SETS
There are several different code sets you can use for identifying language variations. 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:
$lvar = code2langvar('en','alpha-2');
$lvar = code2langvar('en',LOCALE_CODE_ALPHA_2);
The codesets currently supported are:
alpha
This is the set of alphanumeric codes from the IANA language registry, such as 'arevela' for Eastern Armenian.
This code set is identified with the symbol "LOCALE_LANGVAR_ALPHA".
This is the default code set.
ROUTINES
code2langvar ( CODE [,CODESET] )
langvar2code ( NAME [,CODESET] )
langvar_code2code ( CODE ,CODESET ,CODESET2 )
all_langvar_codes ( [CODESET] )
all_langvar_names ( [CODESET] )
Locale::Codes::LangVar::rename_langvar ( CODE ,NEW_NAME [,CODESET] )
Locale::Codes::LangVar::add_langvar ( CODE ,NAME [,CODESET] )
Locale::Codes::LangVar::delete_langvar ( CODE [,CODESET] )
Locale::Codes::LangVar::add_langvar_alias ( NAME ,NEW_NAME )
Locale::Codes::LangVar::delete_langvar_alias ( NAME )
Locale::Codes::LangVar::rename_langvar_code ( CODE ,NEW_CODE [,CODESET] )
Locale::Codes::LangVar::add_langvar_code_alias ( CODE ,NEW_CODE [,CODESET] )
Locale::Codes::LangVar::delete_langvar_code_alias ( CODE [,CODESET] )
These routines are all documented in the Locale::Codes::API man page.
