What is the CD command and what is it for in the Linux operating system?
You should not forget that the structure with which Linux works is Command + Argument within a directory, folder, and file environment. This is why there are a lot of commands that you can use in the terminal. One of those is CD, which is directly related to the location of the directories.
The CD command is a utility used in the Linux operating system to know the path of a directory and get all kinds of additional information. It is also used to change to the directory that has been visited before or to the immediate superior where you are.
Its syntax for navigating the directory tree is
CD [OPCIÓN que desees ingresar] Nombre del fichero que quieres encontrar. In case of not adding the argument, the command returns the home directory that the user has. That is, if you enter
CD [OPCIÓN], in case the command in question is accompanied by a middle dash (-), the command executes the opening of the above directory. By this we mean that you will be able to receive the data from the parent directory, the one that contains the file you are looking for.
What are the parameters accepted by the CD command in Linux?
The parameters that are usually used in the CD command within a Linux terminal are:
/f: used to modify the unit and the file in which you are at the moment of executing the action.
[unidad]: this parameter is used to indicate the disk drive on which the command is to be executed. For example, it can be to: or F:. You must bear in mind that this option will change according to the number of units you have on your computer.
[ruta]: This parameter is used with the CD command to specify the path or path of the directory from which information is to be obtained.
[..]:2 points are placed when specific information is needed about a subdirectory immediately below the current one. This is also known as a child file.
/?: with this argument you can get help on the operation of the CD command. It is very useful because it will help you at all times, so we recommend that you always have it at hand to be able to move forward quickly.
-: when you want to go to a user’s home directory, you will have to use the middle dash. In this way you will be able to know all the data that is housed in this section.
~: This symbol is used to go to the Linux home page.
ls: this argument is added to list the contents of a file.
