The job file is the actual file that ecFlow will submit to the system. Starting with the following ecFlow file:
task.ecf
%manual OPERATORS: Set the task complete and report next day %end %include <head.h> echo do some work sleep %SLEEPTIME% echo end of job %include <end.h>
This uses the header files head.h, end.h for example as given earlier and with SLEEPTIME defined as having a value 60.
After pre-processing the job-file will include the header files and variables and exclude comments and man pages. It would look something like:
task.job1
#!/bin/ksh set -e # stop the shell on first error set -u # fail when using an undefined variable set -x # echo script lines as they are executed # Defines the variables that are needed for any communication with ECF export ECF_PORT=%ECF_PORT% # The server port number export ECF_HOST=%ECF_HOST% # The name of ecf host that issued this task export ECF_NAME=%ECF_NAME% # The name of this current task export ECF_PASS=%ECF_PASS% # A unique password export ECF_TRYNO=%ECF_TRYNO% # Current try number of the task export ECF_RID=$$ # record the process id.
