Top Forums Shell Programming and Scripting Matching 10 Million file records with 10 Million in other file Post 302655427 by vguleria on Wednesday 13th of June 2012 07:09:06 AM

The OS is linux, it's a one time job(occasionally). these are offline files and not being updated. Need to make a process for future requirements.

Its not in DB.. actually these are application log files.
The size of files are 1.5G approx. Right now only thinking of the best way/approach to complete the task...
Had tried using perl hashes(didn't work), i guess keeping that much data in memory is not possible... hence algorithm has to be really efficient here.Smilie


Sample files:
Input.txt
Code:
20.04.2012 11.08.44;RECV;APPNAME@HOSTNAME06:11496059192;processed;Location;contact;status;email_id;2
20.04.2012 11.08.44;RECV;APPNAME@HOSTNAME06:11496059168;processed;Location;contact;status;email_id;1
20.04.2012 11.08.44;RECV;APPNAME@HOSTNAME06:11496059220;processed;Location;contact;status;email_id;2

Status.txt
Code:
APPNAME@HOSTNAME06:11496059192;SUCCESS
APPNAME@HOSTNAME06:11496059224;SUCCESS
APPNAME@HOSTNAME06:11496059168;FAILURE
APPNAME@HOSTNAME06:11496059220;FAILURE
APPNAME@HOSTNAME06:11496059193;SUCCESS

need to update the status field in input.txt with the status(success/failure) in status.txt

svn_add - Schedules the addition of an item in a working directory

SYNOPSIS
bool svn_add (string $path, [bool $recursive = true], [bool $force = false]) DESCRIPTION
Adds the file, directory or symbolic link at $path to the working directory. The item will be added to the repository the next time you call svn_commit(3) on the working copy. PARAMETERS
o $path - Path of item to add. Note Relative paths will be resolved as if the current working directory was the one that contains the PHP binary. To use the calling script's working directory, use realpath(3) or dirname(__FILE__). o $recursive - If item is directory, whether or not to recursively add all of its contents. Default is TRUE o $force - If true, Subversion will recurse into already versioned directories in order to add unversioned files that may be hiding in those directories. Default is FALSE RETURN VALUES
Returns TRUE on success or FALSE on failure. NOTES
Warning This function is EXPERIMENTAL. The behaviour of this function, its name, and surrounding documentation may change without notice in a future release of PHP. This function should be used at your own risk. EXAMPLES
Example #1 svn_add(3) example In a working directory where svn status returns: $ svn status ? foobar.txt <?php svn_add('foobar.txt'); ?> ...will schedule foobar.txt for addition into the repository. SEE ALSO
