43 - history显示 ZooKeeper 客户端/CLI 的版本。例如：
[zk: localhost:2181(CONNECTED) 44] version
ZooKeeper CLI version: 3.9.1-1398af177833412e9ead6b9bb737dc9fd7418a45, built on 2023-10-04 09:54 UTC退出 CLI 窗口。例如：
[zkshell: 1] quit关闭此客户端/会话。例如：
[zkshell: 0] close
2019-03-09 06:42:22,178 [myid:] - INFO [main-EventThread:ClientCnxn$EventThread@528] - EventThread shut down for session: 0x10007ab7c550006
2019-03-09 06:42:22,179 [myid:] - INFO [main:ZooKeeper@1346] - Session: 0x10007ab7c550006 closed打开/关闭是否打印监听信息（watche）的开关。例如：
[zkshell: 0] printwatches
printwatches is on
[zkshell: 1] printwatches off
[zkshell: 2] printwatches
printwatches is off
[zkshell: 3] printwatches on
[zkshell: 4] printwatches
printwatches is on在 leader 和 followers 之间同步一个节点的数据（异步同步），例如：
[zkshell: 14] sync /
[zkshell: 15] Sync is OK使用历史索引，重新执行某条历史命。语法如下：
redo cmdno其中，cmdno 为历史命令的索引，从 0 开始。
例如：
[zkshell: 4] history
0 - ls /
1 - get /consumers
2 - get /hbase
3 - ls /hbase
4 - history
[zkshell: 5] redo 3
[backup-masters, draining, flush-table-proc, hbaseid, master-maintenance, meta-region-server, namespace, online-snapshot, replication, rs, running, splitWAL, switch, table, table-lock]连接 ZooKeeper 服务器。语法如下：
connect host:port其中，host 为主机地址，port 为端口。
例如：
[zkshell: 4] connect
2019-03-09 06:43:33,179 [myid:localhost:2181] - INFO [main-SendThread(localhost:2181):ClientCnxn$SendThread@986] - Socket connection established, initiating session, client: /127.0.0.1:35144, server: localhost/127.0.0.1:2181

connect "localhost:2181,localhost:2182,localhost:2183"
# 连接远程服务器
[zkshell: 5] connect remoteIP:2181获取特定路径下的所有子节点数，例如：
[zkshell: 1] getAllChildrenNumber /
73779
[zkshell: 2] getAllChildrenNumber /ZooKeeper
2
[zkshell: 3] getAllChildrenNumber /ZooKeeper/quota
0获取此会话创建的所有临时节点，例如：
# 创建临时节点
[zkshell: 1] create -e /test-get-ephemerals "ephemeral node"
Created /test-get-ephemerals
# 查看回话创建的临时节点
[zkshell: 2] getEphemerals
[/test-get-ephemerals]
[zkshell: 3] getEphemerals /
[/test-get-ephemerals]
# 创建新的临时节点
[zkshell: 4] create -e /test-get-ephemerals-1 "ephemeral node"
Created /test-get-ephemerals-1
# 查看创建的临时节点
[zkshell: 5] getEphemerals /test-get-ephemerals
test-get-ephemerals test-get-ephemerals-1
[zkshell: 6] getEphemerals /test-get-ephemerals
[/test-get-ephemerals-1, /test-get-ephemerals]
[zkshell: 7] getEphemerals /test-get-ephemerals-1
[/test-get-ephemerals-1]
