Yes I want my output lines in mysql table to contain the lowest(first) and highest (last) value for a particular id_name and media value.
so as you mentioned I would like my table to contain entries like this :

| PSK_30s1189731L001 | -1 | 1 | 3 | 999 | 7285 | 9808 | c |

or should it be one of the input lines). If one of the input lines, does it matter which one?

>Does the order of the lines in the table in your output matter?
The order of lines dont matter in my required mysql table

I missed the' | ' ! Error from my part.

@Don :
For the question :Why doesn't your sample output contain the 2nd header line from your sample input?

I am not sure whether you are asking for the small sample I provided or the input and final output.

Eithercase.

Considering the small snippet sample:

given input :
Code:
 
id_name | model | mode | media| first | end | id | level |
+--------------------+-------+---------+-----+-------+-------+--------+--------+
| PSK_30s1207681L002 | -1 | 1 | 5 | 14026 | 14684 | 6255 | q |
| PSK_30s1207681L002 | -1 | 1 | 5 | 14026 | 14838 | 6255 | q |
| PSK_30s1207681L002 | -1 | 1 | 5 | 14026 | 15236 | 6255 | q |
| PSK_30s1207681L002 | -1 | 1 | 5 | 14026 | 15423 | 6255 | q |
| PSK_30s1207681L002 | 1 | 1 | N | 14026 | 15627 | 6255 | q |

I take PSK_30s1207681L002 and media =5 and look for the smallest first entry and highest end value .

Hence in case of PSK_30s1207681L002 & media =5 I will have only one entry
Code:
| PSK_30s1207681L002 | -1 | 1 | 5 | 14026 | 15423 | 6255 | q |

The 2nd line in sample input is contained within the ranges
Code:
| PSK_30s1207681L002 | -1 | 1 | 5 | 14026 | 14838 | 6255 | q |

i e 14026 and 14838 falls within range 14026 and 15423

So I dont need that entry in my table.

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.
