.In megatest.config
------------------
[setup]
reruns 5
------------------

Replace the default blacklisted environment variables with user supplied
list.

Default list: USER HOME DISPLAY LS_COLORS XKEYSYMDB EDITOR MAKEFLAGS MAKEF MAKEOVERRIDES

.Add a "bad" variable "PROMPT" to the variables that will be commented out
in the megatest.sh and megatest.csh files:
-----------------
[setup]
blacklistvars USER HOME DISPLAY LS_COLORS XKEYSYMDB EDITOR MAKEFLAGS PROMPT
-----------------

Run time limit
++++++++++++++

-----------------
[setup]
# this will automatically kill the test if it runs for more than 1h 2m and 3s
runtimelim 1h 2m 3s

----------------------------
$MT_MEGATEST -env2file .ezsteps/${stepname}	  
----------------------------

Triggers
~~~~~~~~

In your testconfig or megatest.config triggers can be specified 

-----------------
[triggers]

# Call script running.sh when test goes to state=RUNNING, status=PASS
RUNNING/PASS running.sh

# Call script running.sh any time state goes to RUNNING
RUNNING/ running.sh

# Call script onpass.sh any time status goes to PASS
PASS/ onpass.sh
-----------------

Scripts called will have; test-id test-rundir trigger test-name item-path state status event-time, added to the commandline.

HINT

To start an xterm (useful for debugging), use a command line like the following:

-----------------
[triggers]
