Just want to run INFO against a redis server? Don't have redis-cli installed? Think installing it will take longer than writing a python script to run the same command? Don't care if INFO is longer than ~1018 characters? Then this is the python for you!

simple-redis-cli.py

#!/usr/bin/python

# Thanks to https://gist.github.com/glynnbird/89ad23c2f5e218d067f0de76150598e0 for gen_redis_proto()

import sys
import socket

def gen_redis_proto(cmd):
  # break the command by spaces to get the number of tokens
  tokens = cmd.split(" ")
  proto = "*" + str(len(tokens)) + "\r\n"
  for token in tokens:
    proto += "$" + str(len(token)) + "\r\n"
    proto += token + "\r\n"
  return proto

BUFFER_SIZE = 1024

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((sys.argv[1], int(sys.argv[2])))
s.send(gen_redis_proto("INFO"))
data = s.recv(BUFFER_SIZE)
s.close()

# does this look like a redis response?
if len(data) < 1:
  raise Exception("0 length response from redis server")

if data[0] != '$':
  raise Exception("Unexpected redis response, does not start with $")

new_line = data.index("\n")

data_length = int(data[1:new_line])

if new_line + 1 + data_length > BUFFER_SIZE:
  data_length = BUFFER_SIZE - 1 - new_line

data_response = data[new_line+1:new_line+1+data_length]

print data_response
