Found one quirk..
The -x option already calls iocInit, so cannot load more databases nor call iocInit in the command file.

This works:

softIocPVA -x blah -m MACRO=value -d whatever.db   selfdestruct.cmd

with selfdestruct.cmd then just

epicsThreadSleep(5)
dbpf "blah:exit" 0



So to test a periodically dropping IOC:

while true
do
  softIocPVA -x blah -m MACRO=value -d whatever.db   selfdestruct.cmd
  sleep 1
done


Thanks,
Kay
