yuvtoppm - convert Abekas YUV bytes into a portable pixmap
SYNOPSIS
yuvtoppm width height [imagedata]
DESCRIPTION
Reads raw Abekas YUV bytes as input. Produces a portable pixmap as output. The input file is just YUV bytes. You have to specify the
width and height on the command line, since the program obviously can't get them from the file. The maxval is assumed to be 255.

rawtoppm - convert raw RGB bytes into a portable pixmap
SYNOPSIS
rawtoppm [-headerskip N] [-rowskip N] [-rgb|-rbg|-grb |-gbr|-brg|-bgr ] [-interpixel|-interrow] width height [imagedata]
DESCRIPTION
Reads raw RGB bytes as input. Produces a portable pixmap as output. The input file is just RGB bytes. You have to specify the width and
height on the command line, since the program obviously can't get them from the file. The maxval is assumed to be 255. If the resulting
image is upside down, run it through pnmflip -tb .
OPTIONS -headerskip
If the file has a header, you can use this flag to skip over it.
-rowskip
If there is padding at the ends of the rows, you can skip it with this flag.
-rgb -rbg -grb -gbr -brg -bgr
These flags let you specify alternate color orders. The default is -rgb.
-interpixel -interrow
These flags let you specify how the colors are interleaved. The default is -interpixel, meaning interleaved by pixel. A byte of
red, a byte of green, and a byte of blue, or whatever color order you specified. -interrow means interleaved by row - a row of red,
a row of green, a row of blue, assuming standard rgb color order. An -interplane flag - all the red pixels, then all the green,
then all the blue - would be an obvious extension, but is not implemented. You could get the same effect by splitting the file into
three parts (perhaps using dd), turning each part into a PGM file with rawtopgm, and then combining them with rgb3toppm.

Hi,
What is installation package and how to create it?
When we run:

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.
