How do I exclude strings from .bash_history?

I could not find a way to do this after searching online-I need it to avoid logging passwd's when I initialize smbclient at boot.

I believe what you're looking for is the HISTIGNORE environment variable.

Or if you don't want the bash history ever saved to disk, you can unset HISTFILE at the end of you bash config file.

[just brew it!]

Just a FYI... if you've got a reasonably modern kernel (with CIFS support), you should be able to mount the remote file system via your fstab instead, providing the password via a credentials file that is only accessible by root. I don't know exactly what you're trying to do, but in general that's a better all-around way of accessing the server, since it looks just like any other mounted filesystem.
