How to do mass insert in redis

A basic and fairly easy way to do mass insert in redis : Command to use: echo -e "$(cat redis_mass_insert.txt)" | redis-cli --pipe Content of file "redis_mass_insert.txt": *3\r\n$5\r\nlpush\r\n$5\r\nu:m:1\r\n$5\r\nvalu1\r\n*3\r\n$5\r\nlpush\r\n$5\r\nu:m:1\r\n$7\r\nmyvalue\r\n Result: All data transferred.

Here's the snapshot of the whole procedure: To check how the command is responding: use hexdump -C Command: echo -n $'$3\r\nset\r\n$3\r\nkey\r\n$5\r\nvalue\r\n ' | hexdump -C whose output will be something like 00000000 24 33 0d 0a 73 65 74 0d 0a 24 33 0d 0a 6b 65 79 |$3..set..
