cd to the directory where you have the files and execute below command. You may redirect the output to a temporary file.
The command first lists all the files under the directory and picks the filename ($9) and size ($5). You may adjust this if you are getting the filename and size in different positions.
The fiesize is output as first field and the filename follows. I have used "." as an output delimiter to easily fetch the file with maximum size.
I created below files in a directory called tempdir:
The output was as below.
The first field in the output is the maximum size of the file starting with 2nd field (i.e., LAJ, etc) in bytes.
i have a file with some 1000 entries it will contain entries like
1000,ram
2000,pankaj
1001,rahim
1000,ram
2532,govind
2000,pankaj
3000,venkat
2532,govind
what i want is i want to extract only the distinct rows from this file
so my output should contain only
1000,ram... (2 Replies)

__________________________________________________________________________________________________________________________________________________NAME
img-jpeg - Img, Joint Picture Expert Group format (jpeg)
SYNOPSIS
package require Tk
package require img::jpeg ?1.4?
image create photo ?name? ?options?
_________________________________________________________________DESCRIPTION
The package img::jpeg is a sub-package of Img. It can be loaded as a part of the complete Img support, via package require Img, or on its
own, via package require img::jpeg.
Like all packages of Img it does not provide new commands, but extends the existing Tk command image so that it supports files containing
raster images in the Joint Picture Expert Group format (jpeg). More specifically img::jpeg extends Tk's photo image type.
The name of the new format handler is jpeg. This handler provides new additional configuration options. See section JPEG OPTIONS for more
detailed explanations.
All of the above means that in a call like
image create photo ?name? ?options?
[1] Image data in jpeg format (options -data and -file) is detected automatically.
[2] The format name jpeg is recognized by the option -format. In addition the value for the option is treated as list and may contain
any of the special options listed in section JPEG OPTIONS.
JPEG OPTIONS
The handler provides six options, two effective when reading from a JPEG image, and five influencing the writing of such. One option is
usable for both reading an writing.
-fast This option is for reading from JPEG data. It usage activates a processing mode which is fast, but also provides only low-quality
information.
-grayscale
This option can be used for both reading and writing of JPEG data. Usage of this option forces incoming images to grayscale, and
written images will be monochrome.
-quality n
This option is for writing JPEG data. It specifies the compression level as a quality percentage. The higher the quality, the less
the compression. The nominal range for n is 0...100. Useful values are in the range 5...95. The default value is 75.
-smooth n
This option is for writing JPEG data. When used the writer will smooth the image before performing the compression. Values in the
10...30 are usually enough. The default is 0, i.e no smoothing.
-optimize
This option is for writing JPEG data. It usage causes the writer to optimize the huffman table used to encode the jpeg coefficients.
-progressive
This option is for writing JPEG data. It usage causes the creation of a progressive JPEG file.
