Environment Variable Differences When Using Paramiko

Environment variable differences when using Paramiko

Working with the Channel object instead of the SSHClient object solved my problem.

chan=ssh.invoke_shell()
chan.send('echo $PATH\n')
print (chan.recv(1024))

Use environment variable in SFTP path in Paramiko

You cannot use environment variables in SFTP. You have to use real paths. In this case the real path is /opt/CPsuite-R80/fw1.

If the real path is not fixed, and you really need to obtain the real path from a variable value, you will need to resolve the variable value using a different interface (e.g. using a shell access). And then use the resolved value in SFTP. This is what you do in WinSCP - you execute cd $FWDIR in the shell. And the shell resolves $FWDIR to /opt/CPsuite-R80/fw1. In Paramiko, you can use SSHClient.exec_command to resolve the variable:

stdin, stdout, stderr = ssh.exec_command("echo $FWDIR")
fwdir = stdin.read()

Python - using env variables of remote host with / SSH

ssh.exec_command doesn't interpret the remote .profile. Try this:

ssh.exec_command('. .profile ; cd /home/test/;$run ./test.sh')
