@Neo
Sorry, did not understand you properly. Am i on the wrong way? May you clarify 
I do now want to look at any programming codes. I still want to increase my bash skills.
For now, I do not want realted to cybersecurity. Just want to increase my scripting skills. For now, I only wrote couple little scripts and for instance with last script I learned what is awk and how I can use it. Therefore I am asking a guides where I can find tasks so that I can start writing answer for them.

It is a bit backwards to start with your preferred shell scripting language and then go look for example code that fits your favorite programming languages.

ppmtopgm(1) General Commands Manual ppmtopgm(1) NAME
ppmtopgm - convert a portable pixmap into a portable graymap SYNOPSIS
ppmtopgm [ppmfile] DESCRIPTION
Reads a portable pixmap as input. Produces a portable graymap as output. The output is a "black and white" rendering of the original image, as in a black and white photograph. The quantization formula used is .299 r + .587 g + .114 b. Note that although there is a pgmtoppm program, it is not necessary for simple conversions from pgm to ppm , because any ppm program can read pgm (and pbm ) files automatically. pgmtoppm is for colorizing a pgm file. Also, see ppmtorgb3 for a different way of converting color to gray. And ppmdist generates a grayscale image from a color image, but in a way that makes it easy to differentiate the original colors, not necessarily a way that looks like a black and white photograph. QUOTE
Cold-hearted orb that rules the night Removes the colors from our sight Red is gray, and yellow white But we decide which is right And which is a quantization error. SEE ALSO
