  • zsh has a powerful correction mechanism. If you type a command in the wrong way it suggests corrections. What happend here is that dir is an unknown command and zsh suggests gdir, while maybe ls was what you wanted. If you want to execute gdir hit y (yes) If you want to try to execute dir anyway hit n (no) If you want to execute completely different spelt command like ls hit a (abort) and type your command If you want to execute a similar spelt commant like udir hit e (edit) and edit your command.

  • The ssh command alone will execute the sudo command remotely, but the password will be visible in the terminal as you type it. The two stty commands disable the terminal from echoing the password back to you, which makes the remote sudo act as it does locally.

    stty -echo; ssh -t HOSTNAME "sudo some_command"; stty echo

  • Need to query hundreds of hosts with an ssh command ? Of course you'll have setup keys on all your remote HOSTs. But in the case a key is not present this command will skip that node, proceeding on to the next. -t: Force pseudo-tty allocation. This can be used to execute arbitrary screen-based programs on a remote machine. Also prevents unwanted stty messages being sent to console -q: Quiet mode. -o "BatchMode yes" If set to yes, passphrase/password querying will be disabled. This option is useful in scripts and other batch jobs where no user is present Show Sample Output

    ssh -tq -o "BatchMode yes" $HOST <some_command> >> to_a_file

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'.

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.
