I have a script that asks for input from the user. When I run this locally it does what I want however I'd really like to run it over ssh.

I've tried the regular ways I'd run a script:

ssh someaccount@somemachine 'mysscript.sh'

ssh someaccount@somemachine 'bash -s' < myscript.sh'

but when it runs it does not wait for any user input and doesn't allow you to chose from the menu.

# Bash Menu Script Example

echo -n "What machine is sick ?"
  read machine

PS3='Please enter your choice: '
options=("Ping $machine" "Option 2" "Option 3" "Quit")
select opt in "${options[@]}"
    case $opt in
        "Ping $machine")
            echo "you chose to ping $machine"
                        ping -c1 $machine
        "Option 2")
            echo "you chose choice 2"
        "Option 3")
            echo "you chose choice 3"
        *) echo invalid option;;


  • select takes numbered options.

To run an interactive command via the ssh command line you need to tell ssh to allocate a tty on the remote end. (Usually it doesn't bother, and most of the time this is a good assumption.) Add the -t flag to allocate a tty:

ssh -t someaccount@somemachine mysscript.sh
  • No thats not working either. I set up to default redhat machines. Please take a look at the screen shot to see what I'm seeing picpaste.com/pics/… Thanks.

  • This fixed it for me unix.stackexchange.com/questions/100652/… ssh -t root@redhat1 "$(<test2.sh)"

  • @user610209 so your script isn't on the remote server? Why didn't you say so, and why didn't you report the error you would have received when trying to run a script on the remote server that didn't exist? Commented Feb 21, 2015 at 8:17
  • From initial question - "When I run this locally it does what I want however I'd really like to run it over ssh." Run over ssh i.e. run it remotely. Thanks for your help.

  • @user610209, OK. I'd assumed from your first example that you had the script on the remote machine. Either way, though, I'm pleased you're sorted with a solution. Commented Feb 21, 2015 at 16:36

You have to do :

root@debian:/home/mohsen# ssh [email protected] "~/test.sh"
[email protected]'s password: 
What machine is sick ?
1) Ping  3) Option 3
2) Option 2      4) Quit
Please enter your choice: 1
you chose to ping
PING ( 56(84) bytes of data.
64 bytes from icmp_req=1 ttl=64 time=0.370 ms

--- ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 0.370/0.370/0.370/0.000 ms
Please enter your choice: 

Syntax of remote run is :

ssh account@remote_machin  "command_for_run_on_remote_machine"

Above syntax have been used to backup for sysadmins.

  • Thanks for the reply but that doesn't seem to be working for me either. It behaves exactly the same as if I used the 2 methods mentioned in my question. Any other suggestions ?

  • I think it's related to sshd_config Commented Feb 20, 2015 at 13:06
  • You can do it : ssh -v [email protected] "~/test.sh" Commented Feb 20, 2015 at 13:14
