Note that the additional command-line argument -slog tells Metview to provide more output - this can be useful to diagnose problems. This argument (and indeed all other arguments) must come before the -b, and anything after it will be interpreted as an argument to your macro. |
Getting Environment Variables
Environment variables can be queried, not only in batch mode but also in interactive mode. This can be an alternative way to pass information to a macro.
From a command line, inspect the current environment variables with:
| Code Block | ||
|---|---|---|
| ||
env | sort |
and choose one, for example HOST, which provides the name of the machine you are working on. In a macro, get the value of this variable using the getenv() function. For example:
| Code Block | ||
|---|---|---|
| ||
machine = getenv('HOST')
print('Running on ', machine) |
