When I input this command, in a Win cmd box, with the proper keyfile, userid and PAR-adddress:
plink -i [keyfile] [userid]@[PAR-address] GetStatus -a
or this command:
plink -i [keyfile] [userid]@[PAR-address] ViewLog -backup
I get the expected output to the screen or I can pipe to a text file as expected.
If I input this command or others in the CLI manual:
plink -i [keyfile] [userid]@[PAR-address] 'UpdateSystem --SystemName "System1" --Description "Description for System 1"'
I get this error:
"Please supply a valid command:"
The CLI user I was using initially was a systems admin but did not have the rights to edit accounts/systems. So I created another CLI user and gave that user ISA over a specific Collection containing the accounts I wanted to update and that worked.
