linux的主目录是什么
Linux主目录是用户的家目录，添加用户的时候指定的。对于不同用户，主目录不同。~ 表示Linux中的主目录，在终端中输入cd ~命令就能返回到主目录中，前提是有用户目录。
目录是Linux系统组织文件的一种特殊文件。
用户主目录是系统管理员增加用户时创建起来的(以后也可以改变)，每个用户都有自己的主目录，不同用户的主目录一般互不相同。
用户刚登录到系统中时，其工作目录便是该用户主目录，通常与用户的登录名相同。
用户可以通过一个~字符来引用自己的主目录。
例如命令
/home/WANG\$ cat ~/class/software_1
和下面的命令
/home/WANG\$ cat /home/WANG/class/software_1
意义相同。Shell将用用户主目录名来替换~字符。目录层次创建好之后，用户就可以把有关的文件放到相应的目录中，从而实现对文件的组织。
