# delete TLOG_LEVEL environment variable, default is info
unset TLOG_LEVEL

unset TLOG_FILE
```

## server

## 服务端设计
1. 服务端维护一个全局表，包括IP、port、sockfd、to_fd、name
```c++
typedef struct CliInfo {
    char IP[INET_ADDRSTRLEN]; //INET_ADDRSTRLEN = 16
    int port;
    int sockfd;
    int to_fd;
    char name[20];
} CliInfo;
```

## 客户端设计

1. 客户端执行的时候，第一条命令`cli -n ui &`，会在本地创建一个`/tmp/fifo_cli + _name`的fifo，在后台运行
第二个命令`cli -n ui -I`会进入`input_loop`，和创建的fifo进行通讯，两次的name必须一样
