Terminal Commands CentOS 7
Everyone who is learning the basics of Linux can use a small cheat sheet to help you getting to know the system better. There are 3 rows in the table below. The first one displays the command, the second one will show you what the command does, and last but not least, the last column gives optional (extra) information about the command. All the commands are listed for the terminal of CentOs 7. If you have any suggestions regarding the list, please let me know in the commands, I will add them if needed.
If you want to start using CentOs, you can download it from their website. Choosing a Linux distro is a hard task, if you want to create a (web)server environment I can really recommend CentOS as it’s quite stable and there’s a lot of documentation available if you require.
