nano
GNU nano was designed to be a free replacement for the Pico text editor, part of the Pine email suite from The University of Washington. It aimed to "emulate Pico as closely as is reasonable and then include extra functionality". The Debian GNU/Linux distribution, known for its strict standards in distributing truly "free" software (i.e. software with no restrictions on redistribution), would not include a binary package for Pine or Pico. Many people had a serious dilemma: they loved these programs, but the versions available at the time were not truly free software in the GNU sense of the word. GNU nano is a small and friendly text editor. Besides basic text editing, nano offers features like undo/redo, syntax coloring, interactive search-and-replace, auto-indentation, line numbers, word completion, file locking, backup files, and internationalization support. Starting with version 4.0, nano no longer hard-wraps an overlong line by default.

WildEdit
If you ever need to make the same changes to many files at once, then WildEdit will save you a lot of time. It is an interactive tool for users to edit a set of plain text files in a folder hierarchy, filtered by wildcards. This makes it ideal for editing web pages and software source code or reformatting log files and newsletters. It is not suitable for editing files with proprietary binary formats, such as Microsoft Word documents. You simply need to specify the search text, optionally using a regular expression, the replacement text, and a wildcard filter, then let it run. This process can be repeated as often as is required, and up to the last 10 changes can be undone and redone. WildEdit is available as a trial version before you buy it, so please download your trial copy now, and find out just how productive you can be. You can edit any files containing plain text.
