# HBase Shell接口介绍
您可以使用Shell在服务端直接对HBase进行操作。HBase的Shell接口同开源社区版本保持一致，请参见<https://learnhbase.wordpress.com/2013/03/02/hbase-shell-commands/>
Shell命令执行方法：
进入HBase客户端任意目录，执行以下命令。
***hbase shell***
进入HBase命令行运行模式（也称为CLI客户端连接），如下所示。
```
hbase(main):001:0>
```
您可以在命令行运行模式中运行***help***命令获取HBase的命令参数的帮助信息。
#### 注意事项
**count**命令不支持条件统计，仅支持全表统计。
#### 获取HBase replication指标的命令
通过Shell命令"status"可以获取到所有需要的指标。
- 查看replication source指标的命令。 *hbase(main):019:0> status 'replication', 'source'*
  输出结果如下：
  ```
  version 2.2.3

  BLR1000006595:
  SOURCE: PeerID=1, SizeOfLogQueue=0, ShippedBatches=0, ShippedOps=0, ShippedBytes=0, LogReadInBytes=1389, LogEditsRead=4, LogEditsFiltered=4, SizeOfLogToReplicate=0, TimeForLogToReplicate=0, ShippedHFiles=0,

  SizeOfHFileRefsQueue=0, AgeOfLastShippedOp=0, TimeStampsOfLastShippedOp=Wed May 25 20:44:42 CST 2016, Replication Lag=0 FailedReplicationAttempts=0
  ```
  
- 查看replication sink指标的命令。 *hbase(main):020:0> status 'replication', 'sink'*
  输出结果如下：
  ```
  version 2.2.3
  1 live servers
  BLR1000006595:
  SINK : AppliedBatches=0, AppliedOps=0, AppliedHFiles=0, AgeOfLastAppliedOp=0, TimeStampsOfLastAppliedOp=Wed May 25 17:55:21 CST 2016
  ```
  
- 同时查看replication source和replication sink指标的命令。 *hbase(main):018:0> status 'replication'*
  输出结果如下：
  ```
  version 2.2.3

  BLR1000006595:
