In the previous 3 posts, we have covered several Linux terms that you should know when getting started managing a Linux server. What follows are some actual commands that will help you as you begin your journey.
cd – Probably the command you will use most frequently, “cd” stands for “change directory”. From the command line interface (CLI), it is the only effective way to navigate through your filesystem.
ls – Another frequently used one, ls tells Linux to list the files in a directory.
chmod – Permissions are very important for access control and security, and chmod is the command you use to actually change those permissions.
sudo or su – Depending on your distribution, you might use one or the other. Both essentially do the same thing, elevate your system priveleges to the level you specify, usually Root (administrator or super user).
touch – This is a quick way to create an empty file. Simply type “touch” followed by the filename. You can later edit the file and put whatever you want in it.
We will cover several more commands in part 2 of this series, some of which are critical to your server’s performance and stability.
