The above script is saved in "command" variable and is to be run on remote server using python and paramiko.

stdin,stdout,stderr= ssh_conn.exec_command(command)

The output does not represent the working of the command in last line "echo $cmd" the command saved in cmd variable does not work.

Answer 1

Did you try the script on your computer ? If you want the string inside your cmd variable to execute inside your echo you must add backquotes around it

cmd="some command to run on server"
echo "The solution is"
echo `$cmd`

Answer 2

cmd = `some commad`
echo $cmd
Use ` ` quotes to execute your command
