Reducing text file using similar lines
Hello,

I am a java programmer but want to try unix for a purpose where I need to reduce a file using its first field.. Here is the sample data:

HTML Code:
admin;2;0;[yrral];[]
admission;8;0;[timlu];[]
aman;1;0;[ev];[]
caroline;0;4;[];[luis, asethi]
cook;0;4;[];[shekhar, raj]
cook;2;0;[lew];[]
far;0;3;[];[venk]
far;1;5;[shekhar];[venk, raj]
I am explaining the dataset first. There are five fields separated by ";". First field is the main id, second and third are numerics, and 4th and 5th fields are list.

I need to combine all lines in the file where the first field matches. By Combination means, The 2nd and 3rd fields should be added and 4th anf 5th fields (lists) should be combined uniquely.

So, the desired output should be:
HTML Code:
admin;2;0;[yrral];[]
admission;8;0;[timlu];[]
aman;1;0;[ev];[]
caroline;0;4;[];[luis, asethi]
cook;2;4;[lew];[shekhar, raj]
far;1;8;[shekhar];[venk, raj]

I could have done this java but want to use the power of unix to get it done fast, since I have tonnes of such very large files.

Thanks a lot.
Shekhar

html::formfu::element::recaptcha

HTML::FormFu::Element::reCAPTCHA(3pm)			User Contributed Perl Documentation		     HTML::FormFu::Element::reCAPTCHA(3pm)

NAME

       HTML::FormFu::Element::reCAPTCHA - "Are you human" tester!

SYNOPSIS

	   ---
	   elements:
	     - type: reCAPTCHA
	       name: recaptcha
	       public_key: $recaptcha_net_public_key
	       private_key: $recaptcha_net_private_key

DESCRIPTION

       A wrapper around Captcha::reCAPTCHA.  The reCAPTCHA fields aren't added to the form as "real" FormFu fields - so the values are never
       available via params, etc.  You can check that the reCAPTCHA verified correctly, by the usual methods: "submitted_and_valid" in
       HTML::FormFu or "has_errors" in HTML::FormFu

       This element automatically adds HTML::FormFu::Constraint::reCAPTCHA to itself - you should never add it yourself.

       Although this is a subclass of HTML::FormFu::Element::Multi, you should not call "element()" or "elements()" to try to add other fields -
       consider the reCAPTCHA element a black box.

METHODS

   name
       Required. Although not visibly used for anything, you must give this field a name for the reCAPTCHA constraint to work correctly.

   public_key
       Arguments: $public_key

       Required. Obtained from <http://recaptcha.net>.

   private_key
       Arguments: $private_key

       Required. Obtained from <http://recaptcha.net>.

   ssl
       Default Value: 'auto'.

       Valid Values: '1', '0' or 'auto'

       Whether to load the recaptcha.net files via "http" or "https".

       If set to "auto", it will use "https" urls if the current page is running under ssl, otherwise it will use "http" urls.

   recaptcha_options
       Arguments: \%options

       See the recaptcha.net API for details of valid options.

	   recaptcha_options:
	     lang: de
	     theme: white

   constraint_args
       Arguments: \%constraint_args

       Options that will be passed to the HTML::FormFu::Constraint::reCAPTCHA that is automatically added for you.

	   ---
	   elements:
	     - type: reCAPTCHA
	       name: recaptcha
	       constraint_args:
		 message: 'custom error message'

SEE ALSO

       Is a sub-class of, and inherits methods from HTML::FormFu::Element::_Field, HTML::FormFu::Element::Multi, HTML::FormFu::Element::Block,
       HTML::FormFu::Element
