Hi @Marshall-Hallenbeck,

Thank you for your PR, however I do not understand why you would want that. Right now, there are three cases:

Username and password specified in command line:

smbclientng -u 'Administrator' -p 'Admin123!' --target '10.0.0.201'

Username specified in command line, and ask for password interactive:

Since you have not specified --no-pass you will be prompted for a password

smbclientng -u 'Administrator' --target '10.0.0.201'

Username specified in command line, and no password:

Since you have specified --no-pass you will not be prompted for a password:

smbclientng -u 'Administrator' --no-pass --target '10.0.0.201'

Feel free to correct me if I did not understand why you proposed this fix! I am closing the PR for now but will reopen it if needed.

Best regards,

[Marshall-Hallenbeck]

This still prompts a user for a password if they include the -p argument, but do not pass in an actual password. It still keeps the previous functionality.

--no-pass seems verbose when you can just... not include the -p argument.

Thank you!
Merged!
