Command Line Editing

bash uses a library (a shared collection of routines that different programs can use) called Readline to implement command line editing. We have already seen some of this. We know, for example, that the arrow keys move the cursor but there are many more fea - tures. Think of these as additional tools that we can employ in our work. It’s not impor- tant to learn all of them, but many of them are very useful. Pick and choose as desired.


Note: Some of the key sequences below (particularly those which use the Alt key) may be intercepted by the GUI for other functions. All of the key sequences should work properly when using a virtual console.
