What am I doing wrong? Why is it failing?

Answer 1

I think redis is expecting lines terminated by \r or \r\n. If you're doing this on linux, you'll get \n terminated lines, which redis can't parse.

Try this, in the same directory where you entered the other commands:

# rm $$
# for i in {0..10} ; do printf "SET Key$i Value$i\r\n" >> $$ ; done
# cat $$ | redis-cli --pipe

Whoever wrote that tutorial was probably working on Mac or Windows, which happened to produce the appropriate line terminators.
