pcxtoppm - convert a PCX file into a portable pixmap
SYNOPSIS
pcxtoppm [-stdpalette] [-verbose] [pcxfile]
DESCRIPTION
Reads a PCX file as input. Produces a portable pixmap as output. Supported PCX types are:
Colormapped files with 2-16 colors.
"Packed pixel" format (1, 2 or 4 bits/pixel, 1 plane) or bitplane format (1 bit/pixel, 1-4 planes). The program checks the colormap
and uses an internal one if the provided colormap is completely black.
Colormapped files with 256 colors
8 bits/pixel, 1 plane, colormap at the end of the file.
24bit truecolor files
24bit RGB: 8 bits/pixel, 3 planes.
32bit truecolor files
24bit RGB + 8bit intensity: 8 bits/pixel, 4 planes.
OPTIONS -stdpalette
Enforce the use of the internal colormap for files with 16 colors or less.

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
