# 文件目录结构

termux运行目录在：/data/data/com.termux/files

如果没有root权限，文件只有termux可以读写。

使用`export`,即可查看默认设置的系统变量。

```
#$HOME
/data/data/com.termux/files/home

#$PREFIX
/data/data/com.termux/files/usr
```

* 打开termux默认的目录是：$HOME
* 软件安装目录一般是：$PREFIX/bin
* 软件配置文件一般在：$PREFIX/etc

查看软件安装位置：

```
# 查看安装位置，以及配置文件目录
whereis bash

# 查看安装位置
which bash
```

`ls -a`，查看目录里的文件。

`cd`切换目录

```
# 进入home目录
cd $HOME

# 回到上级目录
cd -
```
