Thanks RudiC and Don for reply .
Just trying to make it more precise for better understanding ( Dropping the insert idea into DB2 tables )
1.you want the number of lines in each selected file - 1,
I would like to take just the count of latest file based on timestamp and previous timestamp file count .
a) Compare both counts ( if latest file >= old File --> just assign FLAG=SUCCESS
b) Compare both counts (if latest file < 10% of old File --> just assign FLAG=SUCCESS
c) Compare both counts (if latest file < 0 --> just assign FLAG=FAIL
2.all of the files you want to process can be selected by the filename matching pattern /var/tmp/*/*.csv,
yes , file pattern will be filename_timestamp ( exam ARCH_20171202.csv)
Lets use only one path /var/tmp/
3.all filenames end with an eight digit date string in the format YYYYMMDD followed by the string .csv, and
yes
4.within each directory under /var/tmp, the string before the date string is a constant?
yes
5.Do you want the line count from each selected file in a directory or do you want the sum of the line counts from the selected files in all of the directories containing *.csv files?
Lets have only file counts . use only one path /var/tmp/
I would like to use python instead of unix/perl . Using windows 7.
let me know for any questions

ppmtosixel
ppmtosixel(1) General Commands Manual ppmtosixel(1)
NAME
ppmtosixel - convert a portable pixmap into DEC sixel format
SYNOPSIS
ppmtosixel [-raw] [-margin] [ppmfile]
DESCRIPTION
Reads a portable pixmap as input. Produces sixel commands (SIX) as output. The output is formatted for color printing, e.g. for a DEC
LJ250 color inkjet printer.
If RGB values from the PPM file do not have maxval=100, the RGB values are rescaled. A printer control header and a color assignment table
begin the SIX file. Image data is written in a compressed format by default. A printer control footer ends the image file.
OPTIONS
-raw If specified, each pixel will be explicitly described in the image file. If -raw is not specified, output will default to com-
pressed format in which identical adjacent pixels are replaced by "repeat pixel" commands. A raw file is often an order of magni-
tude larger than a compressed file and prints much slower.
-margin
If -margin is not specified, the image will be start at the left margin (of the window, paper, or whatever). If -margin is speci-
fied, a 1.5 inch left margin will offset the image.
PRINTING
Generally, sixel files must reach the printer unfiltered. Use the lpr -x option or cat filename > /dev/tty0?.
BUGS
Upon rescaling, truncation of the least significant bits of RGB values may result in poor color conversion. If the original PPM maxval was
greater than 100, rescaling also reduces the image depth. While the actual RGB values from the ppm file are more or less retained, the
color palette of the LJ250 may not match the colors on your screen. This seems to be a printer limitation.
