How do I change directories using Paramiko?
I posted the above question regarding a persistent error message that I receive using Paramiko. I do not think it is related to my next question, but it might be.
I can successfully connect to my server via SSH using Paramiko. I can execute commands like ls or pwd. What I can't seem to do is change directories. I can send the command "cd .." for example, but when I follow up with "pwd" it shows that I haven't changed directories. It just lists the initial directory I am in when I log in.
>>> stdin, stdout, stderr = myssh.exec_command("pwd") >>> stdout.readlines() ['/big/dom/home/myid\n'] >>> stdin, stdout, stderr = myssh.exec_command("cd ../") >>> stdout.readlines()  >>> stdin, stdout, stderr = myssh.exec_command("pwd") >>> stdout.readlines() ['/big/dom/home/myid\n'] >>>
Am I misunderstanding what is going on here? Should I not be able to change directories? Or if I can, should I be doing it in some other way than using exec_command?
This guy had it figured out: http://www.vertigrated.com/blog/2010/02/python-remote-ssh-with-paramiko/
You just have to send multiple commands with one exec_command, such as:
myssh.exec_command('cd ..; pwd')
Then stdout.readlines() will return the directory that you changed to.
As of version 2.1+ the method to change directories is sftp.chdir('path/to/directory')
Well paramiko creates an instance of shell and all the commands that you wish to execute in paramiko have to be given in that instance of shell only.
For example: Let us say I have some folder in the directory I am in.
folder1 folder2 folder3
Now if I want to cd into folder 1 and make a directory there what I would do is:
ssh.exec_command('cd folder1;mkdir folder4')
if you write it like:
ssh.exec_command('cd folder1') ssh.exec_command('mkdir folder4')
you would get the result like
folder1 folder2 folder3 folder4
as those were two different instances of the shell and would be independent in their function.
A bit late with this one, but its possible to 'invoke_shell' and write to the standard input through a file.

Seems a little bit heavyweight since you can just ';'.join(cmdlist) and send to the exec_command.
