Hi there,
sry all for my bad english
i have this script but need to modify something if anyone can do it for me ,
this script need to start it in my linux box in process to monitor and when user deplete CPU or MySQL or something in (10%) need to suspend that user for 15MIN.. for example in manual command

/scripts/suspendacct user
/scripts/unsuspendacct user

#!/bin/bash

uidHelp="-u starting uid, must be an integer greater than or equal to 0 (only used with \"-w users\")"

watchHelp="-w what to watch, must be \"users\" or \"procs\""
emailHelp="-e must contain an email address"
debugHelp="-d specifies debug mode in which -e, -m, and -u do not need to be specified."
