Hi Danmero,

Thanks a lot for posting the code. I apologise for your frustating experience with trying to understand the tables. I ran the code, however it throws an error:

'test1.sh: line 3: syntax error near unexpected token `do
'test1.sh: line 3: `do

also I forgot to mention that each of my files is in a subdirectory. So the directory hierarchy is as follows:
root_folder-->ABC-->ABC.txt
-->CDF-->CDF.txt

So I changed a code a bit as follows:

Code:
for filename in $(find -iname '*.txt') 
do
 awk -F"\t" ' 
    BEGIN {OFS="|"} {print $2,$14,$15,FILENAME}
    ' $filename > output.txt
done

filesize - Gets file size

SYNOPSIS
int filesize (string $filename) DESCRIPTION
Gets the size for the given file. PARAMETERS
o $filename - Path to the file. RETURN VALUES
Returns the size of the file in bytes, or FALSE (and generates an error of level E_WARNING) in case of an error. Note Because PHP's integer type is signed and many platforms use 32bit integers, some filesystem functions may return unexpected results for files which are larger than 2GB. EXAMPLES
Example #1 filesize(3) example <?php // outputs e.g. somefile.txt: 1024 bytes $filename = 'somefile.txt'; echo $filename . ': ' . filesize($filename) . ' bytes'; ?> ERRORS
/EXCEPTIONS Upon failure, an E_WARNING is emitted. NOTES
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
file_exists(3). PHP Documentation Group FILESIZE(3)
