Sooner or later, every PC user has to deal with the command line and the problem of how to call the command line. And if the first acquaintance with the console may seem simply horrific, then after a brief introduction - it can greatly simplify your work at the computer and allow you to more deeply understand the functionality of the operating system.
Familiarization with the command line (it is also a terminal or console) is necessary because you need to understand what it is, what it is for, and how to call the command line under a particular operating system.
So the console is a kind of software product (runtime with a text interface), the main purpose of which is to provide direct interaction between the operating system itself and the user of this system.
The Windows 7 command line, whose commands are similar for all Windows operating systems, is represented by the
cmd.exe command interpreter
. How to call the command line in this case is a question that does not cause difficulties, because judging by the name alone, we can say that this is done by the cmd.exe command. After its launch, a black window appears in front of the user with a prompt line, where you need to enter commands.
What can be done using the command line? Yes, everything is the same as with the usual graphical interface. It is logical that the user may have a question about why then use it. First of all, it will significantly reduce the use of computer memory, which may affect system performance. Secondly, very often typing a command in the console is much simpler and faster than looking for similar functionality in the operating system. For example, to find out the ip-address of a machine, in the terminal it is enough to type one ipconfig command, while in the graphical interface an ordinary user needs to spend at least several minutes searching for such information.
Linux command line appearance is no different from the Windows command line. But, despite this, it has a different set of commands, the purpose of which is similar, as in the above system. In this case, you can launch such a command shell by selecting the “Terminal” application in the main menu or by using
hot keys (Ctrl + Alt + F1).
It is worth noting separately that some commands can be executed only with administrator or root privileges. How to call a command line with such rights? Yes, elementary. In Windows operating systems, just right-click on the icon and select “Run as administrator”, and on Linux, type sudo in the terminal itself, and then enter the root password.
Despite the many advantages of the command line, not all users will be happy to work with it, especially those who are used to the rich graphical interface, since a black screen may seem rather boring and mediocre to many. Therefore, to use it or not - it is already up to the user to decide, based on the task assigned to him and the options for its execution.
