Understanding Linux Files and Users

Summary

In this chapter, we examined how the SUSE Linux file system lies at the heart of an understanding of how the operating system works. We also discussed how the file system and user accounts go hand-in-hand and are inextricably linked. This involved discussing the concept of file ownership and usage permissions, plus how these can be manipulated using command-line shell tools.

We also discussed the overall structure of the SUSE Linux file system and how external file systems can be mounted and made available within SUSE Linux. Finally, we looked at how to find files and how to gauge how much free space there is within the file system.

In the next chapter, we’ll look at how the BASH shell can be used to view and otherwise manipulate text files, which are also important to the way SUSE Linux works.
