Using optparse

[loial]

A shell script is passing parameters to my python script in the
following format

-PARAM1 12345 -PARAM2 67890

Can I parse these with optparse ? If so how?

I can't seem to get it to work. It seems to expect --PARAM1 and --
PARAM2

You are out of luck. Quoting

http://docs.python.org/library/optparse.html

"""
There are many different syntaxes for options; the traditional Unix syntax
is a hyphen (“-“) followed by a single letter, e.g. "-x" or "-F". Also,
traditional Unix syntax allows multiple options to be merged into a single
argument, e.g. "-x -F" is equivalent to "-xF". The GNU project
introduced "--" followed by a series of hyphen-separated words,
e.g. "--file" or "--dry-run". These are the only two option syntaxes
provided by optparse.

See the doc:

Some other option syntaxes that the world has seen include:
[...]
* a hyphen followed by a whole word, e.g. "-file" [...]

These option syntaxes are not supported by optparse, and they never will be.

You might try using shlex instead.
