The command level interface is provided by the 'ecflow_client' executable. By calling:
ecflow_client --help
We can get the list of all the available commands.
Most users of ecFlow will be happy to use ecflowview, but some things cannot be done using ecflowview. Note also that most of the commands that you execute using ecflowview are actually CLI commands and that you can execute CLI commands in ecflowview's collector window.
CLI is command line based, which means it reads your commands a line at the time.
The very first argument to 'ecflow_client' must begin with '–'
ecflow_client --load=/my/home/fred.def
For further information please see the ecFlow reference manual.
