Hi, I have a huge file which is about 50GB. There are many lines. The file format likes
The question is that there are a few duplicate rows. The definition of the duplicate is meant the second column is repeated. It doesn't mean the entire line are exactly same, just the the second column.
In the above example, line 3 and 4 can be defined as duplicate. The have the same string
We can remove either of them.
The delimeter could be a white space or tab.
After remove the duplicate lines the result will be saved in a new file.
I am doing KSH script to remove duplicate lines in a file. Let say the file has format below.

Hello Folks,
Can some one help me with the removal of duplicate lines from a log file and send it to another log file. It's bit complicated as two lines are same but only difference is the timestamp, but some lines are uniq. Line has been seperated by colon's.

Locale::Codes::LangExt(3pm) Perl Programmers Reference Guide Locale::Codes::LangExt(3pm)NAME
Locale::Codes::LangExt - standard codes for language extension identification
SYNOPSIS
use Locale::Codes::LangExt;
$lext = code2langext('acm'); # $lext gets 'Mesopotamian Arabic'
$code = langext2code('Mesopotamian Arabic'); # $code gets 'acm'
@codes = all_langext_codes();
@names = all_langext_names();
DESCRIPTION
The "Locale::Codes::LangExt" module provides access to standard codes used for identifying language extensions, 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 extensions. 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:
$lext = code2langext('acm','alpha');
$lext = code2langext('acm',LOCALE_LANGEXT_ALPHA);
The codesets currently supported are:
alpha
This is the set of three-letter (lowercase) codes from the IANA language registry, such as 'acm' for Mesopotamian Arabic.
This is the default code set.
ROUTINES
code2langext ( CODE [,CODESET] )
langext2code ( NAME [,CODESET] )
langext_code2code ( CODE ,CODESET ,CODESET2 )
all_langext_codes ( [CODESET] )
all_langext_names ( [CODESET] )
Locale::Codes::LangExt::rename_langext ( CODE ,NEW_NAME [,CODESET] )
Locale::Codes::LangExt::add_langext ( CODE ,NAME [,CODESET] )
Locale::Codes::LangExt::delete_langext ( CODE [,CODESET] )
Locale::Codes::LangExt::add_langext_alias ( NAME ,NEW_NAME )
Locale::Codes::LangExt::delete_langext_alias ( NAME )
Locale::Codes::LangExt::rename_langext_code ( CODE ,NEW_CODE [,CODESET] )
Locale::Codes::LangExt::add_langext_code_alias ( CODE ,NEW_CODE [,CODESET] )
Locale::Codes::LangExt::delete_langext_code_alias ( CODE [,CODESET] )
These routines are all documented in the Locale::Codes::API man page.
