gmemusage [ options ]


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
