I have a bash script test.sh that contains the following commands

#!/bin/bash



PASSWORD=""

USERNAME=""

REM_HOSTNAME='localhost'



FILES_TO_COPY="remote_exec.sh"





function scptmp {

    exec sshpass -p $PASSWORD scp -o "ConnectTimeout 3" 

        -o "StrictHostKeyChecking no" 

        -o "UserKnownHostsFile /dev/null"

}

echo -e "Execute..."

sshpass -p "$PASSWORD" ssh -oStrictHostKeyChecking=no -t $USERNAME@$REM_HOSTNAME "echo $PASSWORD | sudo -S bash /tmp/$FILES_TO_COPY"

And the remote_exec.sh with the following content:

#!/bin/bash



hostname=`hostname`

mkdir $hostname

When I execute the script with

bash test.sh

I don't receive any error, but the remote_exec.sh doesn't seem to be executed on the host since no directory is created.

Does anyone have an idea what the problem might be?

Single quotes inhibit evaluation of variables inside them. Try double quotes:

sshpass -p $PASSWORD ssh -t user@host "echo $PASSWORD | sudo -S bash /tmp/remote_exec.sh"

  Does it work if you just type the above command line in, replacing both instances of $PASSWORD by the actual password (as well as the user and host placeholders)? If not, then something else is wrong. If yes, I'm not sure why the above would not work.
