Below is my script \"pause_run\" it will, in a VERY ugly way, throttle a process by pausing and running it. Drop me a line if you actually use this!
# This script copied from check_ext_net on 2003-09-01 - although not much is left.
# By Leonard Chan (firstname.lastname@example.org)
# Pause_run takes three parameters.
# 1) seconds of pause time.
# 2) seconds of run time.
# 3) name of program to pause
# Programs are paused with \"killall -STOP [progname]\" and started with killall -CONT.
# Primary use for this is to attempt to keep the CPU cool on my old server during backups.
# I will \"pause_run\" either the tar or gzip processes (samba would screw up the network!)
# sleep 10
# if not 3 params, give some instructions and exit.
# - I suppose $0 is the name of the script...
if [ $# -ne 3 ]
echo \"Usage - $0 x y z\"
echo \" x - pause seconds. y - run seconds. z - program to pause-run\"
# do the pause-run two step.
echo \"To stop pause-run, you have to kill it. (Ctrl+Break)\"
# loop somehow. well, 2 will never equal 3...
while [ 2 -ne 3 ]
# pause the proggie
killall -STOP $3
# run again
killall -CONT $3
# wait again
