The variables that are used by ecFlow, like ECF_HOME.
- The variables that are defined by the user.They should not start with “ECF”.It is good practice to name these variables with capital letters.
- The variables that are generated by ecFlow, and that you can use inyour jobs, like ECF_DATE which contains the date of the suite.
Ecf Script
In the previous example, we have copied the file t1.ecf to the file t2.ecf.
Edit those two files so they call the unix sleep command with a variable
called SLEEP as a parameter.

def create_family_f1():
f1 = ecflow.Family("f1")
f1.add_task("t1").add_variable("SLEEP", 20)

return f1
print "Creating suite definition"
defs = ecflow.Defs()
suite = defs.add_suite("test")
suite.add_variable("ECF_INCLUDE", os.getenv("HOME") + "/course")
suite.add_variable("ECF_HOME", os.getenv("HOME") + "/course")
suite.add_family( create_family_f1() )
print defs
print "Checking job creation: .ecf -> .job0"
print defs.check_job_creation()
print "Saving definition to file 'test.def'"
defs.save_as_defs("test.def")
