The linux cd command is used to switch the current working directory, with the syntax format "cd [dirName]", in which the dirName representation can be an absolute path or a relative path; if the directory name is omitted, it is changed to the user's home directory, which is the directory where login was just located.

The Linux cd command is used to switch the current working directory to dirName (directory parameter).

The dirName representation can be an absolute path or a relative path. If the directory name is omitted, change to the user's home directory (that is, the directory where you were just login).
