gmemusage(1) General Commands Manual gmemusage(1)NAME
gmemusage - graphically display memory used by running processes.
SYNOPSIS
gmemusage [ options ]
DESCRIPTION
Gmemusage is modelled after the program of the same name on Silicon Graphics' workstations. Gmemusage graphically displays the contents of
memory on a running system, broken up by individual processes. The display is a stacked bar graph with the height of an area representing
the RSS size of the corresponding process. In addition, the process name, number of processes with that name and the size (in kilobytes)
are shown.
Processes which take up less memory than a (user-specifiable) threshhold are merged into a single area on the graph. Multiple processes
with the same name are merged into a single area.
While running, gmemusage accepts the following keys:
Q or q
Exit the program.
Up Arrow
Increase the minimum threshhold by 10 kb.
Down Arrow
Decrease the minimum threshhold by 10 kb.
Other keys are (not-so-silently!) ignored.
OPTIONS
Gmemusage accepts the following command-line options (defaults in brackets):
-name resourcename
Class name to use for resources (Gmemusage)
-display display
X server to contact ($DISPLAY environment variable)
-geometry geometry
Initial window geometry (320x400)
-font font
Use font font for drawing text (fixed)
-background color
Color to use for window background (grey4)
-update seconds
Update interval (5 seconds)
-threshhold kb
Threshhold below which small processes are merged (400 kb)
-ncolors #colors
How many different colors to use (3)
-color1 color
Name of first color (red/maroon)
-color2 color
Name of second color (green/OliveDrab)
-color3 color
Name of third color (blue/SlateBlue)
-color[4-9] color
Names of remaining colors (undefined)
-help
Print a short help message.

cmap - format of .cmap files (color maps)
DESCRIPTION
Color-map files define the mapping between eight-bit color numbers and red, green and blue intensities used for those numbers. They are
read by Magic as part of system startup, and also by the :load and :save commands in color-map windows. Color-map file names usually have
the form x.y.z.cmapn, where x is a class of technology files, y is a class of displays, z is a class of monitors, and n is a version number
(currently 1). The version number will change in the future if the formap of color-map files ever changes. Normally, x and y correspond to
the corresponding parts of a display styles file. For example, the color map file mos.7bit.std.cmap1 is used today for most nMOS and CMOS
technology files using displays that support at least seven bits of color per pixel and standard-phosphor monitors. It corresponds to the
display styles file mos.7bit.dstyle5.
Color-map files are stored in ASCII form, with each line containing four decimal integers separated by white space. The first three inte-
gers are red, green, and blue intensities, and the fourth field is a color number. For current displays the intensities must be integers
between 0 and 255. The color numbers must increase from line to line, and the last line must have a color number of 255. The red, green,
and blue intensities on the first line are used for all colors from 0 up to and including the color number on that line. For other lines,
the intensities on that line are used for all colors starting one color above the color number on the previous line and continuing up and
through the color number on the current line. For example, consider the color map below:
255 0 0 2
0 0 255 3
255 255 255 256
This color map indicates that colors 0, 1, and 2 are to be red, color 3 is to be blue, and all other colors are to be white.
