Debugging with echo over socket #31

$ nc -Ulk /tmp/socket
# -U  - open unix socket
# -l  - open for listening
# -k  - keep open for multiple connections

import socket
conn = socket.socket(socket.AF_UNIX, socket.SOCK_STREAM)
conn.connect('/tmp/socket')
# ^ this will fail if nobody is listening on Unix socket

def echo(msg):
    conn.sendall(msg + '\n')
echo('--- start ---')
echo(sys.executable)
