Editing user-manager users from terminal or API - possible?

When I type:

> /tool user-manager user print where name=fred

I get:

 0     subscriber=TestSub name="fred" password="fred" group-name="1M" 
       uptime-used=1h9m23s download-used=11733964 upload-used=1827814 
       last-seen=feb/12/2009 16:39:18 credit-count=1 credit-left=1m 
       credit-duration=1m credit-price=20 credit-time-added=1m

However, I am unable to change any of the credit details (e.g. to give credit to the user) and typing:

> /tool user-manager user export

gives:

.
.
add comment="" disabled=no group-name=1M name=fred password=fred subscriber=TestSub
.
.

Adding payments using

> /tool user-manager payment add subscriber=TestSub user=fred credit=Day

for example, doesn’t work (and, bizarrely, the price shows as ‘4294967295’).

So, the question is, how do I add a user from the command line and give them some credit.

All of this is possible from the user-manager web page, so surely it must be do-able from the command line?

Thanks,

Nick.

/tool user-manager user add

/tool user-manager user add username=user add-credit=

Ah. OK. Thank you.

Is there a wiki page which describes all the commands and options - this must have been the only thing I didn’t try!!!

Thanks,

Nick.
