Several ways Python calls the shell

1.

cmd = "Some unix command" Retcode = Subprocess.call (cmd,shell=true)

2.

SSH = Paramiko. Sshclient () ssh.connect (server, Username=username, Password=password) Ssh_stdin, ssh_stdout, Ssh_stderr = ssh.exec_ Command (Cmd_to_execute)

3.

Import Spurshell = Spur. Sshshell (hostname= "localhost", username= "Bob", password= "password1") result = Shell.run (["Echo", "-N", "Hello"]) print Result.output # Prints Hello

4.

Sshprocess = subprocess. Popen ([' ssh ', <remote client>], stdin=subprocess. PIPE, stdout = subprocess.    PIPE) sshProcess.stdin.write ("ls mydirectory\n") sshProcess.stdin.write ("Echo end\n") for line in Stdout.readlines (): if line = = "end\n": Break print (line) sshProcess.stdin.write ("uptime\n") sshProcess.stdin.write ("Echo end\n") for L ine in Stdout.readlines (): if line = = "end\n": Break print (line)
