Join Kevin Skoglund for an in-depth discussion in this video Unix text editors, part of Unix for Mac OS X Users.
In this movie, we are going to take a look at the text editors that…are available for Unix.…If you remember back to our discussion about the history of Unix, Unix has been…around a really long time and it pre- dates all of the graphical user interfaces…in the modern day text editors that we are used to.…So what did they use in those really early days, when Unix had first been invented?…Well, they used a text editor called ed, for edit text, and it was really simple…and is not at all user friendly.…So it's not something that we even want to think about now, but in the early…days that was the very first thing.…Well, then over time people said, "It would be great if we had something that was…more of a visual text editor. We can see the page that we are working with."…And so they came with something called vi.…
That's visual editing mode and later that was improved and replaced with vim.…So you can still type vi, but chances are it will take you into vim, because vim…has pretty much replaced it.…It's just vi with some improvements.…

Q: The exercise files for the following movies appear to be broken:
Is there something wrong with them?
These exercises include one or more "dot files", whose file names start with a period. These files are normally hidden from view by the Finder. So that they would show up in the Finder, the period has been removed from the file names. Additionally, "_example" has been added at the end of the file name to make it clear that the file will not work as-is.
To make the dot files usable, either:
1) Open the file in a text editor to view its contents. Note that it may not be possible to double-click the file to open it because there is no file extension (such as .txt).
2) Resave the file under a new name (usually by choosing File > Save As), adding a "." to the beginning of the file name and removing "_example" from the end.
1) Copy and rename the file from the Unix command line using the techniques discussed in this course. Rename the file by adding a "." to the start and removing "_example" from the end. Include the "-i" option to prevent overwriting an existing file unexpectedly.
Example: cp -i ~/Desktop/Exercise\ Files/Chapter_07/07_02_files/bashrc_example ~/.bashrc
