利用shell命令操作Memcached

数据存储（假设key为test，value为12345）

printf"settest005\r\n12345\r\n"|nc127.0.0.112000

STORED

数据取回（假设key为test）

printf"gettest\r\n"|nc127.0.0.112000

VALUE test 0 5

12345

END

数值增加1（假设key为test，并且value为正整数）

printf"incrtest1\r\n"|nc127.0.0.112000

12346

数值减少3（假设key为test，并且value为正整数）

printf"decrtest3\r\n"|nc127.0.0.112000

12343

数据删除（假设key为test）

printf"deletetest\r\n"|nc127.0.0.112000

DELETED

查看Memcached状态

printf"stats\r\n"|nc127.0.0.112000

模拟top命令，查看Memcached状态：

watch"printf'stats\r\n'|nc127.0.0.112000"

或者

watch"echostats|nc127.0.0.112000"
