Your data sample is useless Smilie try to copy/paste again and use [code] tags not [table] tags !

From your spinet
Code:
for filename in *.txt	# you don't need to find anything special and you are in current directory anyway
do
	awk -F"\t" '	# awk have the internal FILENAME variable(read the manual)
				BEGIN {OFS="|"} {print $2,$14,$15,FILENAME}
				' $filename > output.txt
done

Not tested but should work if that's what you want.

fileatime - Gets last access time of file

SYNOPSIS
int fileatime (string $filename) DESCRIPTION
Gets the last access time of the given file. PARAMETERS
o $filename - Path to the file. RETURN VALUES
Returns the time the file was last accessed, or FALSE on failure. The time is returned as a Unix timestamp. EXAMPLES
Example #1 fileatime(3) example <?php // outputs e.g. somefile.txt was last accessed: December 29 2002 22:16:23. $filename = 'somefile.txt'; if (file_exists($filename)) { echo "$filename was last accessed: " . date("F d Y H:i:s.", fileatime($filename)); } ?> ERRORS
/EXCEPTIONS Upon failure, an E_WARNING is emitted. NOTES
Note The atime of a file is supposed to change whenever the data blocks of a file are being read. This can be costly performance-wise when an application regularly accesses a very large number of files or directories. Some Unix filesystems can be mounted with atime updates disabled to increase the performance of such applications; USENET news spools are a common example. On such filesystems this function will be useless. Note Note that time resolution may differ from one file system to another. Note The results of this function are cached. See clearstatcache(3) for more details. Tip As of PHP 5.0.0, this function can also be used with some URL wrappers. Refer to "Supported Protocols and Wrappers" to determine which wrappers support stat(3) family of functionality. SEE ALSO
