How do I specify port number for PuTTY to use with Windows cmd?

I start most of my SSH connections with a windows command like this

cmd://"C:\Program Files\PuTTY\putty.exe" -ssh [email protected]

I assume this defaults to port 22. Now I need to connect on a different port. I tried

cmd://"C:\Program Files\PuTTY\putty.exe" -ssh [email protected]:xxx

(port number on the end) but it won't allow the connection. I know the port number and IP are correct because if I fire up PuTTY and start a session with these details I can get in fine.

p.s. If this is the wrong stackexchange for this question please don't destroy me, I did look for quite a long time before deciding to post here.

Solution 1:

Ok - I'm embarrassed. I just found the -P option which does exactly what I want.

cmd://"C:\Program Files\PuTTY\putty.exe" -ssh [email protected] -P xxx

is the correct syntax.
