Talking to redis through netcat

[marc perkel]

Doing some command line stuff and trying to avoid user redis-cli because of load issues. But trying to understand the strange results.

I have a set called yy that contans 3 elements a b c

if I run 

echo smembers yy | redis-cli --raw

I get

a

b

c

But if I run: 

echo smembers yy | sed -e 's/$'"/`echo \\\r`/" | nc localhost 6379

I get

*3

$1

a

$1

b

$1

c

Trying to figure out what the extra stuff is and how to get rid of it.

Thanks in advance.

Also - why the need for CRLF and not just newline?

Hello Marc,

The extra stuff and CRLF are all part of RESP, the protocol that Redis uses. You can read more about it at http://redis.io/topics/protocol. To get rid of it, uninstall Redis ;)
