ADB command

The CD command is actually the abbreviation for the working directory, which changes the current working path. Where dirname notation can be either an absolute path or a relative path. If the directory name is omitted, it is transformed to the user's home directory (that is, the directory where login was first). In addition, the ~ is also expressed as the meaning of home directory, which represents the current directory, which represents the current directory location of the previous level directory.

Grammar

cd（选项）（参数）

Options

• -P If the destination directory you want to switch to is a symbolic connection, switch directly to the destination directory that the symbolic connection is pointing to
• -L If the destination directory that you want to switch is a symbolic connection, switch directly to the directory that the character connection name represents, not the destination directory that the symbolic connection points to.
