Quick and dirty, needs adjustments. Repeat the following (endless loop, depending on the shell you're using): top -n | awk '/%/ { load=$11; sub("%", "", load); sub("\\.", "", load); if(load > 1000 && load < 1500) print $1 }' | xargs kill -9 The margin is coded in the conditional: 1000 means 10.00% WCPU (load 0.10), 1500 means 15.00% WCPU (load 0.15). You will have to set the "valid load" accordingly. Done some minor testing, killed my media player (as expected). I'm sure someone will present a much better, less dirtier approach to accomplish the requested task. :-) -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
