What are the basic terminal commands?
Answer
The terminal in Linux-based operating systems is a powerful system management tool that allows you to perform any administrative tasks faster and more efficiently than through a graphical interface. To work confidently in the command line, it is enough to learn a few basic commands with which every system administrator begins their journey.
•The ls command is used to display the contents of the current directory, showing a list of files and folders. By adding the -l flag to it, you can get detailed information about access rights, size, and modification date, while the -a flag will allow you to see hidden files starting with a dot.
•The cd command is used to navigate the file system and change the current directory. For example, the cd /var/log command will move you to the system logs folder, and a simple cd command without parameters will return you to the current user's home directory.
•To manage files and directories, three classic commands are used: cp for copying files, mv for moving or renaming objects, and rm for permanently deleting data from the system.
•The sudo command stands for SuperUser Do and allows you to execute any command specified after it with root superuser privileges. This is necessary for installing programs, changing system configurations, and managing services.
•If you forget the syntax of any command or the purpose of its keys, the built-in help system comes to the rescue, which is called by the man command before the name of the desired utility, for example, man command, which opens a detailed manual.
