# If the compile succeeds, you'll find several Redis binaries in the src directory, including:
# redis-server: the Redis Server itself
# redis-cli is the command line interface utility to talk with Redis.
# To install these binaries in /usr/local/bin, run:
make install

#Usage: redis-cli [OPTIONS] [cmd [arg [arg ...]]]
#Examples:
#  cat /etc/passwd | redis-cli -x set mypasswd
#  redis-cli get mypasswd
#  redis-cli -r 100 lpush mylist x
#  redis-cli -r 100 -i 1 info | grep used_memory_human:
#  redis-cli --quoted-input set '"null-\x00-separated"' value
#  redis-cli --eval myscript.lua key1 key2 , arg1 arg2 arg3
#  redis-cli --scan --pattern '*:12345*'
#When no command is given, redis-cli starts in interactive mode
#redis-cli的命令提示非常有帮助,比其他终端好用的多
