What others think

It may work, but it's a bad habit to put passwords on the command line.

Another user could see them using 'ps'.

Use public key authentication!

1) sshpass can take a password via the following additional methods:

- file

- file descriptor

- environment variable (I think)

2) echo the password (environment variable / fd / etc) client side in to the ssh pipe to prevent it from being seen on the server side.

3) use PKI when ever possible.

I haven't tested this, but I don't think that it's necessary -- sudo should prompt for the password via stderr and wait patiently until you provide it. ... you may be prompted for a series of passwords in succession, but as long as you can keep them straight, you should be able to use sudo on the remote machine without providing it on the commandline.
