We’ve discussed how to work with background services, also known as daemons. Our next major topic is networking in Linux, which will build on many of the areas we’ve already touched on so far in this chapter. Networking in Linux We stated earlier in this chapter that our coverage of Linux was intended to get you “up and running” with Linux in the context of network automation and programma‐ bility. Naturally, this means that our discussion of Linux would not be complete without also discussing networking in Linux.
Let’s build on that knowledge with some information on manipulating files and directories. Manipulating Files and Directories Armed with a basic understanding of the Linux file system, paths within the file sys‐ tem, and how to move around the file system, let’s take a quick look at manipulating files and directories.

Moving, Copying, and Renaming Files and Directories When it comes to moving, copying, and renaming files and directories, the two com‐ mands you’ll need to use are cp (for copying files or directories) and mv (for moving and renaming files and directories). Check the man pages! The basic use of all the Linux commands we’ve shown you so far is relatively easy to understand, but—as the saying goes—the Devil is in the details. If you need more information on any of the options, parameters, or the advanced usage of just about any command in Linux, use the man (manual) command.
