Report Generation with Grep

All,

I am pretty new to Unix Environment. I am not sure if my requirement can be accomplished in Unix. I did try searching this forum and others but could not get an answer. Requirement is explained below:

I have a set of files in a folder.
Code:
file1_unload
file2_unload
file3_unload
file1_load
file2_load
file3_load
file1_dat
file2_dat
file3_dat

And each file will have similar type of input. I will just give a files output for example:
file1_unload
Code:
Started at 22:24:32
593456 records unloaded
Ended at 23:08:40

file1_load
Code:
Started at 23:09:01
Loaded records 345298
Ended at 00:12:25

You can similarly imagine values for other unload and load files. And dat files will have the data in ASCII format. Now I want a report be created which looks like the following:

Code:
file1 <file1_dat's size> 593456 22:24:32 23:08:40 00:44:08 345298 23:09:01 00:12:25 01:03:24
file2 <file2_dat's size> <Unld> <UnldSt> <UnldEd> <timeDF> <Load> <LoadSt> <LoadEd> <timeDF>
file3 <file3_dat's size> <Unld> <UnldSt> <UnldEd> <timeDF> <Load> <LoadSt> <LoadEd> <timeDF>



For better understanding, the fields in the report are:
1. Part of the filename (file1, file2 etc.), NOT the entire filename.
2. Respective dat file's size.
3. Unloaded records from the respective Unload file.
4. Start Time from the respective Unload file.
5. End Time from the respective Unload file.
6. Time Difference between 4 and 5th columns.
7. Loaded records from the respective Load file.
8. Start Time from the respective Load file.
9. End Time from the respective Load file.
10. Time Difference between 8 and 9th columns.

Let me know if this can be done in UNIX. If so, please help me do it. Let me know for any questions on the inputs.

Thanks in advance,
Bharath

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. SEE ALSO
