The Linux CD command is used to switch the current working directory to dirName (directory parameters).

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, "~" is also indicated as the home directory meaning, "." is the current directory, "." Represents the current directory location of the previous level of the directory.

CD [DirName]

DirName: The target directory to switch to.
