Memcached常用命令及使用说明——netcat

数据存储（假设key为test，value为12345）

printf "set test 0 0 5
12345
" | nc 127.0.0.1 12000

STORED

数据取回（假设key为test）

printf "get test
" | nc 127.0.0.1 12000

VALUE test 0 5

12345

END

数值增加1（假设key为test，并且value为正整数）

printf "incr test 1
" | nc 127.0.0.1 12000

12346

数值减少3（假设key为test，并且value为正整数）

printf "decr test 3
" | nc 127.0.0.1 12000

12343

数据删除（假设key为test）

printf "delete test
" | nc 127.0.0.1 12000

DELETED

查看Memcached状态

printf "stats
" | nc 127.0.0.1 12000

模拟top命令，查看Memcached状态：

watch "printf 'stats
' | nc 127.0.0.1 12000"

或者

watch "echo stats | nc 127.0.0.1 12000"
