Top Forums Shell Programming and Scripting Ranking data points from multiple files Post 302976001 by ncwxpanther on Wednesday 22nd of June 2016 08:55:45 AM

Thanks Corona. The scripts works as expected.

However there is an added intricacy that I need help with.

For ties - I need the script to rank that tied value the same.

For instance, If there is a rank of 1, 2, 3 but 4, 5, and 6 are tied. The ranks would be 1, 2, 3, 4, 4, 4, 7,....

To add to the complexity, I need to rank at both tails of the range. That way if the tie is on the upper half of the ranks, it would assume the higher value.

For instance, if there is a rank of 100, 99, 98, but 97 and 96 are tied. The ranks would be 100, 99, 98, 97, 97, 95,.....

In order to do this the total number of ranks would need to be divided by 2 to find the midpoint. Any ties less than the midpoint would assume the lower rank. While any ties more than the midpoint would assume the higher rank.

The total number of ranks could be found in the number of files in the sort statement - In this case it would be
Code:
({1900..2016} + 1) / 2 = 59

Is this something that can be done in awk?

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
