In response to White Hat <pigskin_referee@yahoo.com>: > I have seen 'kill -USR2' used in some scripts; > however, I am unable to find out exactly what it is > referring to.

USR2 is a "user defined signal" (from "man signal") It doesn't "mean" anything by definition. Each application is free to define its meaning as it sees fit. It's there specifically so that applications can use signals for special purposes without reusing the defined signals. What scripts are you seeing using this? I expect they're following application-specific behaviour. -- Bill Moran http://www.potentialtech.com
