ppmmake(1) General Commands Manual ppmmake(1)NAME
ppmmake - create a pixmap of a specified size and color
SYNOPSIS
ppmmake color width height
DESCRIPTION
Produces a portable pixmap of the specified color, width, and height.
The color can be specified in five ways:
o A name, assuming that a pointer to an X11-style color names file was compiled in.
o An X11-style hexadecimal specifier: rgb:r/g/b, where r g and b are each 1- to 4-digit hexadecimal numbers.
o An X11-style decimal specifier: rgbi:r/g/b, where r g and b are floating point numbers between 0 and 1.
o For backwards compatibility, an old-X11-style hexadecimal number: #rgb, #rrggbb, #rrrgggbbb, or #rrrrggggbbbb.
o For backwards compatibility, a triplet of numbers separated by commas: r,g,b, where r g and b are floating point numbers between 0
and 1. (This style was added before MIT came up with the similar rgbi style.)

ppmcolormask(1) General Commands Manual ppmcolormask(1)NAME
ppmcolormask - produce mask of areas of a certain color in a PPM file
SYNOPSIS
ppmcolormask color [ppmfile]
DESCRIPTION
Reads a PPM file as input. Produces a PBM (bitmap) file as output. The output file is the same dimensions as the input file and is black
in all places where the input file is the color color, and white everywhere else.
The output of ppmcolormask is useful as an alpha mask input to pnmcomp. Note that you can generate such an alpha mask automatically as you
convert to PNG format with pnmtopng(1). Use its -transparent option.
ppmfile is the input file. If you don't specify ppmfile, the input is from Standard Input.
The output goes to Standard Output.
You can specify color five ways:
o An X11-style color name (e.g. black).
o An X11-style hexadecimal specifier: rgb:r/g/b, where r g and b are each 1- to 4-digit hexadecimal numbers.
o An X11-style decimal specifier: rgbi:r/g/b, where r g and b are floating point numbers between 0 and 1.
o For backwards compatibility, an old-X11-style hexadecimal number: #rgb, #rrggbb, #rrrgggbbb, or #rrrrggggbbbb.
o For backwards compatibility, a triplet of numbers separated by commas: r,g,b, where r g and b are floating point numbers between 0
and 1. (This style was added before MIT came up with the similar rgbi style.)

Introduction
I have seen some misinformation regarding Unix file permissions. I will try to set the record straight. Take a look at this example of some output from ls:
$ ls -ld /usr/bin /usr/bin/cat
drwxrwxr-x 3 root bin 8704 Sep 23 2004 /usr/bin

I have a file which looks roughly like this:
996 mmmmmmm
996 xxxxxxxxxxxxx
99600 ssssssssss
9964 fffffffffffff
and would like to sort it numerically on the first field. I tried:
sort -nr --key=1 ....
The output I get is:
99600 ssssssssss

Suppose I have a main() function with only one malloc statement allocating say some 1 gb memory. Also say my system has 1 gb of ram.
main()
{
malloc(1gb)
return(0)
}
The program above exits without freeing the memory.
In this case will the 1 gb of heap memory be returned... (9 Replies)
I'm trying to install a PGX32 video card on my Sparc 10 Ultra running Solaris 10.

Hey All,
Quick question...
I'm writing a short script to check if a continuous port is running on a server.
I'm using "ps -ef | grep -v grep | grep processName" and I was wondering if it was better/more reliable to just check the
return code from the command or if its better to pipe to... (12 Replies)
I installed NetBSD 6.1.2 amd64 and can't find the apm utility. Is it not in the base system?
Is it necessary to recompile the default amd64 kernel to use apm?
Or is there a new method for power management and suspend/resume? (2 Replies)
Hi,
I am learning shell scripting for the first time. I use AT&T Korn Shell, Version AJM 93u+ 2012-08-01, compiled from source on NetBSD.
So far I have managed to set up what I think is a useful and pleasing shell prompt, which can be seen in the image attached to this post.
The prompt is... (2 Replies)
Hey gang, I have a list of times I need to sum up. This list can vary from a few to a few thousand entries. Now I had found a closed reference to adding time titled "add up time with xx:yy format in bash how?" In it, the example works great for that formatted list of times... This is the reply code...

Usually when I on the evening go to bed I take some interesting book with me. I read it for a while to get me down to sleep. Probably most people seek information from the Nett by googleing but I am so oldfashioned I prefer a real book ;)
