ppmtomap(1) General Commands Manual ppmtomap(1)NAME
ppmtomap - extract all colors from a portable pixmap
DESCRIPTION
This program exists only for backward compatibility.
Use pnmcolormap, which replaced it in January 2002.
One trivial difference between ppmtomap and pnmcolormap all is that if the input is PBM or PGM, ppmtomap would produce PPM output, whereas
pnmcolormap all produces the same kind of output as the input. This should not be very noticeable, though, as PBM and PGM images are usu-
ally usable anywhere a PPM image is.

pnmquant(1) General Commands Manual pnmquant(1)NAME
pnmquant - quantize the colors in a Netpbm image to a smaller set
SYNOPSIS
pnmquant [-center|-meancolor|-meanpixel] [-floyd|-fs] [-nofloyd|-nofs] [-spreadbrightness|-spreadluminosity] ncolors [pnmfile]
All options can be abbreviated to their shortest unique prefix. You may use two hyphens instead of one to designate an option. You may
use either white space or equals signs between an option name and its value.
DESCRIPTION
Reads a PNM image as input. Chooses ncolors colors to best represent the image, maps the existing colors to the new ones, and writes a PNM
image as output.
This program is simply a combination of pnmcolormap and pnmremap, where the colors of the input are remapped using a color map which is
generated from the colors in that same input. The options have the same meaning as in those programs. See their documentation to under-
stand pnmquant.
It is much faster to call pnmcolormap and pnmremap directly than to run pnmquant. pnmquant is just a convenience.
ppmquant is an older program which does the same thing as pnmquant, but on only PPM images. It is, however, faster than either pnmquant or
ppmcolormap/pnmremap.

Hi,
What is installation package and how to create it?
When we run:
in AIX:
installp package1
or
in Linux
rpm -ivh mypackage
What is package1 or mypackage in the abov examples and how to create them and deploy them?
I hope my question is clear enough.
Thank you (2 Replies)
What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.
# When the shell exits, append to the history file instead of overwriting it

After the success of the jq - tool for parsing and manipulating JSON-Data someone wrote a tool called yq, which aims to be the same for YAML, what jq is for JSON. Seems to work fine. I'll definitely give it a chance in future.
