What I need is an awk script to identify unique names from file 2 which are not found in the... (6 Replies)
Hello,
I have a large database in which name homonyms are arranged in a row. Since the database is large and generated by hand, very often dupes creep in. I want to remove the dupes either using an awk or perl script.

Hello,
I have a database of name variants with the following structure:

The number of variants can be as many as thirty to forty.
Since the database is quite large (at present around 60,000 lines) duplicate sets of variants creep in. Thus

Dear all,
I have a large dictionary database which has the following structure
source word=target word

book=tome
Since I want to... (7 Replies)

aptpkg::hash
AptPkg::hash(3pm) User Contributed Perl Documentation AptPkg::hash(3pm)NAME
AptPkg::hash - a helper class for implementing tied hashes
SYNOPSIS
use AptPkg::hash;
DESCRIPTION
The AptPkg::hash class provides hash-like access for objects which have an underlying XS implementation.
Such objects need to add AptPkg::hash to @ISA, provide get, set and exists methods, and an iterator class.
AptPkg::hash
new([XS_OBJECT])
Create a object as a tied hash. The object is implemented as a hash reference blessed into the class, which in turn is tied to
AptPkg::hash.
This means that both $obj->method() and $obj->{key} valid, the latter invoking get/set (through FETCH/STORE).
The tie associates an array reference with the hash, which initially contains a reference to the hash, the XS object and an anon hash
which may be used by subclasses to store state information.
If no XS object is passed, one is created via new in the XS class. The name of that class is constructed from the class name, by
lower-casing the last component and prefixing it with an underscore (eg. AptPkg::Config becomes AptPkg::_config).
If the module contains a @KEYS array, then the private hash will be populated with those entries as keys (see the description below of
the AptPkg::hash::method class).
_self, _xs, _priv
Accessors which may be used in subclass methods to fetch the three array elements associated with the hash reference.
keys(ARGS)
In a scalar context, creates and returns a new iterator object (the class name with the suffix ::Iter appended).
The XS object, the private hash and any arguments are passed to the constructor.
In an array context, the iterator is used to generate a list of keys which are then returned.
The iterator class must implement a next method, which returns the current key and advances to the next.
AptPkg::hash::method
The AptPkg::hash::method class extends AptPkg::hash, providing a simple way to map a fixed set of keys (defined by the @KEYS array) into
method calls on either the object, or the internal XS object.
Classes inheriting from AptPkg::hash::method should provide an iterator class which inherits from AptPkg::hash::method::iter.
