Text Editor for OS X and UNIX Mac Links
Once you begin using UNIX on Mac you begin to have the need for a text editor for Mac. The BASH shell along with a good text editor and you are on your way using UNIX on Mac.
We just wanted to include a link for what is we think the best text editor for Mac. Its called Smultron
http://smultron.sourceforge.net/
Here is a screenshot of it below. If has a number of advanced features over the text editor that ships standard with OS X. There are:
- Multi file management
- Coloring of the text for enhanced readability
- Statistics at the bottom of the application window
- The ability to set certain text as comment
- A host of advanced text editing and management features

The sample file here is SQL, for which it is equally good at managing. It provides far more capability then the TOAD editor (a great tool also, but its SQL Editor is just not in the same ballpark).
TextMate
This is an exceedingly powerful text editor. Actually to call it a text editor is an understatement. TextMate’s includes a database of text libraries and rules called “bundles.” This allows the user to tell TextMate what it is writing in and for TextMate to color the text correctly and help in formatting it. Like Smultron, it can be integrated with the BASH shell.
We do not have the time or inclination to describe TextMate too fully, however, if you fell a bit limited by your current text editor and need something very sophisticated, TextMate is a clear choice.

Also some good books for learning UNIX on Mac are:
