Execute Command/script Using Different Shell In SSH/Paramiko

I am rather new to Linux and Paramiko, but the issue I am having is anytime I attempt to change a shell the remote Paramiko session will hang. The remote host is in /etc/csh by def

Solution 1:

Your question has nothing to do with Paramiko. Try to paste your command in SSH terminal - It won't work either.

---

The syntax aaa ; bbb executes the commands one after another. bbb won't be executed until aaa finishes. Similarly, /bin/bash ; echo $shell executes bash and the echo won't be executed until bash finishes, what it never does, hence the hang.

You actually do not want to execute echo after bash - you want to execute echo within bash.

If you want to execute a script/commands within a different shell, you have three options:

• Specify the shell that the script needs in the script itself using shebang - This the the right way for scripts.

  #!/bin/bash
  

• Execute the script/commands using shell command-line:

  /bin/bash script.sh
  

  or

  /bin/bash -c "command1 ; command2 ; ..."
  

• Write the script/command to be executed to a shell input, like I've shown you in your previous question:
