There are also many other commands, we have only given the most common variants of them.
There are also a number of other important network commands:
Now let's move on to other categories of useful Linux commands.
Reference information and documentation can be accessed using the following commands:
There are 4 most important commands for managing processes:
Here we have two key teams:
Perhaps one of the most important and frequently used Linux console command sets:
This concludes our analysis of Linux commands and tools, which are important for every self-respecting system administrator. Thanks for your attention!
