| ======Text Editing====== | |
| It is possible that you might need to tweak your programs or to view output files. There are many options to edit text on a Linux system. Some are text-only (console mode) and some use a graphical user interface. | |
| |
| =====Nano===== | |
| [[http://www.nano-editor.org/|Nano]] is a very simple console text editor. To use it to edit a file, type: | |
| <code>$ nano [file name]</code> | |
| Note that nano may automatically wrap long lines (unless started with ''-w'') and it does not have an undo function. | |
| |
| =====Gedit===== | |
| [[https://wiki.gnome.org/Apps/Gedit|Gedit]] is a simple GUI text editor. You will need an X-server to run it. It's only installed on some of the machines (econ1-5). | |
| <code>$ gedit [file name]</code> | |
| |
| =====Emacs===== | |
| [[http://www.gnu.org/software/emacs/|Emacs]] is one of the oldest text-editors (along with vi(m)). If you have an X-server running it will start with a GUI otherwise it will automatically start in console-mode. To start, enter the command: | |
| <code>$ emacs</code> | |
| |
| To edit a file, use: | |
| <code>$ emacs [file name]</code> | |
| |
| You can find an interactive emacs tutorial by typing ''C-h t'' (Control+h together, then t). To quit, type ''C-x C-c'' | |
| |
| ======Vim===== | |
| You can run [[http://www.vim.org/|Vim]] with: | |
| <code>$ vim</code> | |
| |
| Upon starting Vim, you will be in 'command mode'. In command mode, you cannot actually edit a file. To edit the file type ''i'' to enter 'insert mode' and type ''Esc'' to return to 'command mode'. A tutorial is available for Vim, by typing '':help'' and pressing enter (in command mode). To quit, type '':quit''+Enter (in command mode). | |
