python paramiko exec_command run local bash script on remote server

[tommyceric]

I am trying to run my local bash script on remote server without copying it into remote server. It is as simple as following for test purpose. There are more than a few servers where it runs perfectly, but in some server running tcsh as default, there is an issue. How do i envoke bash, if following does not work. Below is dummy test.sh . This is only test script, I mean to run complete script.

#!/bin/bash
    a=test
    echo $a
    echo $SHELL

I am using python paramiko, exec_command for remote execution as following:

my_script = open("test.sh").read()
    stdin, stdout, stderr = ssh.exec_command(my_script, timeout=15)
    print(stdout.read().decode())
    err = stderr.read().decode()
    if err:
        print(err)

Given, that connection works and same script works for other servers with bash default shell.

This is the output that i get:

/bin/tcsh

    printing from errors
    a=test: Command not found.
    a: Undefined variable.

I'll lead with this: I have used remote ssh many times but NOT what you are trying. This is me just thinking about your question so here goes. My first thought is to get bash instead of tcsh.

Try "forcing a login shell" as noted at link so you get bash which from what you write seems to work. There are more ideas in that link as well.
