Hello all. I am a newb obviously and a bit stumped on this, so any help gratefully accepted.
The script is extracting metadata from individual mp3 files, then (hopefully will be) sorting them into newly-created subdirectories. I have filtered out the relevant metadata and have the album names... (8 Replies)

I want to remove all rows with a minor repeating count less than 30% compared to the major repeating count from my table. The values of a col(starting col 2) can assume is A,T,G,C and N. Each row has at least 2 values and at most 4 repeating values(out of ATGC).
N is considered a missing value... (12 Replies)
Hello all,
can you explain why this filter does not work, it prints all the lines in the file:
awk -v sel="TestString" 'sel' file while these work:
awk '/TestString/' file
awk -v sel="TestString" '$0~sel' file
Thanks!:) (6 Replies)

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.
