Cd of the linux command

Cd command

Basic operation of directory

The cd command is used to switch the working directory to dirname. 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 the login was just located). In addition, ~ also means home directory. It indicates the directory where it is currently located. Represents the directory above the current directory location.

Grammar

Cd (option) (parameter) option

-p if the target directory you want to switch to is a symbolic link, switch directly to the target directory that the symbolic link points to-L if the target directory you want to switch is a symbolic connection, switch directly to the directory represented by the character connection name, not the target directory that the symbolic link points to. -when only the "-" option is applied, the current working directory will be changed to the directory represented by the environment variable "OLDPWD". Example

Cd enters the user's home directory; cd ~ enters the user's home directory; cd-returns the directory where it was before; cd. Return to the parent directory (if the current directory is "/", it will still be "/"; ".." after execution. " For the meaning of superior directory); cd.. /.. Return to the upper two-level directory; cd! $uses the parameter of the previous command as the cd parameter. Thank you for reading!
