Test connection to Redis with netcat

echo -e '*1\r\n$4\r\nPING\r\n' | nc redis.host.com 6379

Yeah I saw it working about 1 time in 5, but the sleep fixes that. Or this command works instantly:

exec 3<>/dev/tcp/redis.host.com/6379 && echo -e "PING\r\n" >&3 && head -c 7 <&3

That's from this answer which uses a file descriptor bash tcp trick

Thanks!

If redis has a password:

$ echo -e 'AUTH password-here\r\n*1\r\n$4\r\nPING\r\n' | nc -w1 127.0.0.1 6379
