If you are an experienced user, use your method of choice. For new users, we highly recommend using Notepad++ (for Windows), TextWrangler (for Mac), or some other software with the same capability. You can get through the class material using nano
, but a more full-featured option is better for day-to-day work.

nano on Lonestar via sshnano is a very simple editor available on most Linux systems. If you are able to use ssh, you can use nano. To invoke it, just type:
You'll see a short menu of operations at the bottom of the terminal window. The most important are:
Be careful with long lines – sometimes nano will split long lines into more than one line, which can cause problems in our commands files, as you will see. |

Notepad++ for WindowsNotepad++ is an open source, full-featured text editor for Windows PCs (not Macs). It has syntax coloring for many programming languages (Python, Perl, shell), and a remote file editing interface. If you're on a Windows PC download the installer here. Once it has been installed, start Notepad++ and follow these steps to configure it:
To open the connection, click the blue (Dis)connect icon then select lonestar connection. It should prompt for your password. Once you've authenticated, a directory tree ending in your home directory will be visible in the NppFTP window. You can click the the (Dis)connect icon again to Disconnect when you're done. Since much of the editing we'll do will be in your SCRATCH area at TACC, rather than having to navigate around TACC's complex file system tree, let's just create a symbolic link to your SCRATCH directory in your home directory. Then you'll be able to get there just by clicking on the scratch folder in the Notepad++ Remote directory tree.

Editing Text Files on TACC: TextWranglerTextWrangler is a recommended FreeWare text editor for MacOS X. (It even keeps with the theme TACC has going with naming its clusters!) You can use it to directly edit text files on Lonestar with OSXFuse/MacFusion using a nice GUI. It is a much more powerful text editor than TextEdit, and won't trip you up by wrapping lines etc., if you learn to use it. Even if you cannot install OSXFuse/MacFusion, TextWrangler allows you to edit a remote file via SSH. To do this:

Tip: Files beginning in a dot (.) like (.profile_user) are meant to be "hidden" in Linux and won't show up when you are navigating in Finder on a Mac (if using OSXFuse/MacFusion). There is a way to turn on showing these files in finder, but it can get annoying because they will show up everywhere. If you use the TextWrangler "open" command to open a file, there is a box that you can check to show these files. Notepad++ and several other options show these files. Just leave them there; they are settings files that you don't want to delete.
