shell script to process file line by line
Hi ,
I am new to shell scripting (ksh shell) and trying to accomplish few requiremtns.
I have a file with the following format
EMP NO EMP NAME AGE Amt Paid
12 Mark Taylor 32 32333
14 James Brown Smith 23 23232
12 Mark Taylor 32 42333
13 Lary King 56 154545
15 Stevert Clark 34 34434
14 James Smith 23 23232
The script should be able to process the lines , find the lines which are similar excepting the amt paid and merge the similar lines and add the amt paid.
The expected result after running the script should look like this
12 Mark Taylor 32 47666
14 James Brown Smith 23 46464
13 Lary King II 56 154545
15 Stevert Clark 34 34434
As you can see the employee 12 and 14 got updated amt and the redundent lines removed.
Please guide onthe same.
Thanks,
RS.

rdf::vcard::line
RDF::vCard::Line(3pm) User Contributed Perl Documentation RDF::vCard::Line(3pm)
NAME
RDF::vCard::Line - represents a line within a vCard
DESCRIPTION
Instances of this class correspond to lines within vCards, though they could potentially be used as basis for other RFC 2425-based formats
such as iCalendar.
Constructor
o "new(%options)"
Returns a new RDF::vCard::Line object.
The only options worth worrying about are: property (case-insensitive property name), value (arrayref or single string value),
type_parameters (hashref of property-related parameters).
RDF::vCard::Entity overloads stringification, so you can do the following:
my $line = RDF::vCard::Line->new(
property => 'email',
value => 'joe@example.net',
type_parameters => { type=>['PREF','INTERNET'] },
);
print "$line
" if $line =~ /internet/i;
Methods
o "to_string()"
Formats the line according to RFC 2425 and RFC 2426.
o "add_to_model($model, $node)"
Given an RDF::Trine::Model and an RDF::Trine::Node representing the entity (i.e. vcard) that this line belongs to, adds triples to the
model for this line.
o "property()"
Returns the line's property - e.g. "EMAIL".
o "property_node()"
Returns the line's property as an RDF::Trine::Node that can be used as an RDF predicate. Returns undef if a sensible URI cannot be
found.
o "property_order()"
Returns a string which can be used to sort a list of lines into a sensible order.
o "value()"
Returns an arrayref for the value. Each item in the arrayref could be a plain scalar, or an arrayref of scalars. For example the
arrayref representing this name:
N:Smith;John;Edward,James
which is the vCard representation of somebody with surname Smith, given name John and additional names (middle names) Edward and James,
might be represented with the following "value" arrayref:
[
'Smith',
'John',
['Edward', 'James'],
]
or maybe:
[
['Smith'],
'John',
['Edward', 'James'],
]
That's why it's sometimes useful to have a normalised version of it...
o "nvalue()"
Returns a normalised version of the arrayref for the value. It will always be an arrayref of arrayrefs. For example:
[
['Smith'],
['John'],
['Edward', 'James'],
]
o "value_node()"
Returns the line's value as an RDF::Trine::Node that can be used as an RDF object. For some complex properties (e.g. ADR, GEO, ORG, N,
etc) the result is not especially useful.
o "value_to_string()"
Formats the line value according to RFC 2425 and RFC 2426.
o "type_parameters()"
Returns the type_parameters hashref. Here be monsters (kinda).
