17.20.2 Externally injecting variables into job triggers
Context
Job triggers are able to see the variables in the job object to which it is attached. This means that, for triggers that are attached to job objects, another method for supplying variables exists. Updating the job object's variables effectively updates the variable for the trigger.
To externally inject variables into job triggers
- Use the mjobctl -m command to set a variable to attach to a job.
> mjobctl -m var=Flag1=TRUE 1664
The variable Flag1 is set. This will be available to any trigger attached to job 1664.
