redis> SET firstname shekhar

"shekhar"
redis> INCR votes
(integer) 1
redis> INCR votes

redis> INCR votes
(integer) 3
redis> DECR votes
(integer) 2
其他一些操作（包括?APPEND、GETRANGE、MSET?和?STRLENGTH?也可用于字符串。etc設備安裝位置？請參見http://doc.redisfans.com/string/index.html?）
? ? ? ? 有序的字符串列表，按照插入順序排序。Redis 中的列表是一個有序的字符串集合，您可以向其中添加任意數量的（惟一或非惟一）元素。除了向列表添加元素和從中獲取元素的操作之外，Redis 還支持對列表使用取出、推送、范圍和其他一些操作。
使用 LPUSH 命令，最近添加的單詞位于列表頂部，以前添加的單詞會在后面：
redis> LPUSH words austerity
(integer) 1
redis> LPUSH words socialism moratorium socialism socialism
(integer) 5
redis> LRANGE words 0 2
1) "socialism"
2) "socialism"
3) "moratorium"
redis > LLEN words刪除：
(integer) 5
#刪除所有 socialism刪除列表：
redis> LREM words 0 socialism
(integer) 2
redis 127.0.0.1:6379> DEL words
(integer) 1
redis> SADD uniquewords austerity
(integer) 1
redis> SADD uniquewords socialism
(integer) 1
redis> SADD uniquewords socialism
(integer) 0
redis> SMEMBERS uniquewords
1) "austerity"
2) "socialism"
redis> ZADD wordswithlength 9 austerity要獲得有序集的大小，可使用 ZCARD 命令：
(integer) 1
redis> ZADD wordswithlength 7 furtive
(integer) 1
redis> ZADD wordswithlength 5 bigot
(integer) 1
redis> ZRANGE wordswithlength 0 -1
1) "bigot"
2) "furtive"
3) "austerity"
redis 127.0.0.1:6379> ZCARD wordswithlength
(integer) 3
redis> HSET user:1 name shekhar
(integer) 1
redis> HSET user:1 lastname gulati
(integer) 1
redis> HGET user:1
redis> HGET user:1 name
"shekhar"
redis> HGETALL user:1
1) "name"
2) "shekhar"
3) "lastname"
4) "gulati"
