Freedom Environment (F.E. = effie)

Home Page

FE --- a *REALLY OPEN* Open Source system --- all executables are scripts --- for all to see


FREEDOM-EYES --- that is, Freedom-ize!!!


With this Freedom Environment subsystem installed,
you will be able to 'drill-down'
into your Linux/Unix (or Mac?) machine, with mouse clicks,
to see what's there and what's happening
(files, helps, executables, processes, etc.)
--- to depths and breadths never-before-plumbed so easily.

In addition, you can easily do
many kinds of batch file conversions (media files and text files),
many kinds of batch file renaming
(general files, and special renaming of media files),
many kinds of media file editing ... and creation ... and listening/viewing
--- with a small set of mouse clicks ...

... where 'media' refers to

  • audio-only files
  • image/photo files
  • movie files (video-only or video-plus-audio)
  • 3D model files

I'm talking about 'FE Nautilus Scripts'.

Description       Download       Videos

'FE Nautilus Scripts' is a cascade of menus of utility shell scripts
(in categories such as IMAGEtools, AUDIOtools, VIDEOtools,
FILESlists, FINDlists, SPACEtools, ...). The menus are provided by
the Gnome2-Nautilus or MATE-Caja file manager.

The cascading-menu structure is determined by the file structure of
'FE Nautilus Scripts' when its files are installed in a special
scripts directory of the Gnome2 or MATE desktop system.

The sub-directory filenames, like 'IMAGEtools', become the names of sub-menus.
The script filenames in those sub-directories become the 'app-names' in the menus.

The user can change the file structure and the filenames. And the user can
edit the scripts to modify or enhance them. Further, the user can add scripts.


Browse text files with the GUI text browser
which has a unique 'Show-All-Match-Lines' capability
that will blow you away with your search-efficiency gains ---
especially on huge text files such as log files, large config files,
large source code files, long lists, etc. etc. etc. ... even binary files.

I'm talking about 'FE xpg'.

Description       Download       Videos

The 'xpg' utility makes the 'feNautilusScripts' subsystem
and the 'tkGooies' subsystem (see below) more powerful.


Arrange your applications into category menus of your own choosing and
into menu sort orders or item groupings of your own choosing
--- with complete and total access to the
configuration files and scripts that are running the menu system.

I'm talking about 'FE AppMenus'.

Description       Download       Videos

'FE AppMenus' is a system of 'pop-away' toolchests of applications
(in categories such as IMAGEtools, AUDIOtools, VIDEOtools,
and other categories of the user's choosing). The toolchests are
defined by simple 'chest definition' files that can be edited by the user.


Here is a multitude of tkGUI 'apps' in category menus
using a menu/'toolchest' system like that used for 'feAppMenus'.

I'm talking about 'FE tkGooies' --- a family of tkGUI's that
augment the capabilities of 'feNautilusScripts'.

Description       Download

'FE tkGooies' is a system of 'pop-away' toolchests of Tcl-Tk GUI-generating
scripts (in categories such as IMAGEtools, AUDIOtools, VIDEOtools,
3Dtools, PLOTtools, MAPtools, MATHtools, PHYSICStools, ...). The 'tkGooie'
toolchests are defined by simple 'chest definition' files.

Each toolchest has 'drawers'. A click on a toolchest drawer may pop up another
toolchest --- or may pop up a 'tkGooie' GUI. The function of the drawers is
determined by the 'chest definition' files --- which are editable by the user.

This may be of use to people not running Gnome/Nautilus or MATE/Caja :
A 'file-navigator-to-run-a-selected-script-on-selected-files' utility
is available in the 'tkGooies' system --- in the 'FILEmanagers' toolchest.
A description of this utility (composed of two main file-selector Tk GUI's)
is provided at this 'tkScriptApplicator' description page.
This offers another way of running the 'feNautilusScripts'.

If you mess up the configuration of any of these subsystems
and can't figure out how to make it good again,
these are relatively small, non-scattered systems.
They are easy to delete and re-install --- quickly.

No pain, no strain. To infinity and beyond.

Great for 'newbies' --- great for system-administrators
(even those long-in-the-tooth --- near retirement or retired).

Great for everyone in-between.

It's FREEDOM E. --- that is, Freedom-y. Like Truth-y.

We need both --- Freedomy-ness and Truthy-ness ---
on our computers and in our world.

How to remember this web site: It's FreedomEnvy without the 'y' --- dot com.

Jimi said it well
Freedom, that's what I want now ... Freedom, that's what I need now.
Freedom .. to live ... Freedom so I can give.

Foundation of FE :

The 'FE Nautilus Scripts' sub-system is founded on

  • Linux/Unix shell scripts --- and

  • uses the 'zenity' utility to provide GUI prompts for user-input, when needed.

Example of a 'zenity' prompting GUI :

The 'zenity' utility is delivered with many Linux distros. If not, it is usually available via the package manager of the distro.

The FE 'xpg' and 'AppMenus' and 'tkGooies' sub-systems are founded on

Examples (reduced size) of two GUI's done with Tcl-Tk scripts :


Many Linux 'distros' have the Tcl-Tk system installed [including its 'wish' (window shell) interpreter], because there are utilities in the distro that use Tcl-Tk scripting. So, in many cases, you will not need to download a Tcl-Tk package and install it.

If you don't have the Tcl-Tk environment (with the 'wish' interpreter) on your machine, it is probably a few mouse clicks away. Tcl-Tk was not included in my initial install of Ubuntu 9.10, but, in the 'Ubuntu Software Center', I found the TkDiff utility. I installed it in a few clicks, and the install brought along the required Tcl-Tk interpreter environment.

    It turned out that the Tcl-Tk 8.4 'wish' interpreter was installed instead of 8.5. To get nicer anti-aliased fonts in Tk GUIs, one needs 8.5. The 'Xft' system for font anti-aliasing was incorporated in Tk 8.5, but not 8.4.

    Here is a web page that shows how to install the Tcl-Tk 8.5 'wish' interpreter.

Note that because all the FE subsystems are founded on scripting languages, all the source code is available --- for modification, tailoring, and improvement. You can even add scripts to expand these systems.

Tk GUIs :

To see the kinds of things possible with Tcl-Tk scripting, click here for some samples of "tkGUIs" that have been devised, in the 1985 to 2008 timeframe, for various applications.

And here is a slideshow of those sample tkGUIs.

And here is a ALTERNATIVE slideshow of those sample tkGUIs --- which initially fits each image to the size of your browser window.

As components of the FE system are released, you will see more tkGUI examples via the 'Description' and 'Screenshots' links above.

Note that Tcl-Tk is not a dead language, as indicated by an active wiki for Tcler's.

In fact, Tcl-Tk is quite popular with physicists (both astronomical and nuclear --- macro and micro physics) and with engineers (such as electrical, electronics, and telecommunications engineers). Tcl-Tk is commonly used to 'bind together' systems of programs --- in addition to being used for GUI's and scripting within monolithic programs.

Tcl-Tk has many corporate and government users.

Your choice of background (or font) is not saved for when you return to this page. It could be, by using a "cookie", a small file on your computer --- ugh.

When you (re)load this page or return to this page, the background is set according to the hour of the day. Hence it changes every hour --- for some variety.

The fonts may or may not work depending on what your browser knows is available and depending on the fonts available on your machine.

Color table (hex-codes and colors, at

An alternative Color table, and description (in case the link above goes dead)

Let me know if you think some colors on this page should be changed, for backgrounds, borders, links, visited-links, titles, body-text, paragraph-text, or other text elements --- for readability or whatever.

The drop-down menus of image-tiles and background colors could be added-to or changed also. Do you have a beautiful tile to contribute?

I'm looking for a good F.E. (effie) logo. Anyone want to design one and donate it?

Actually, why have one logo? There could be many. (There are thousands of Ubuntu logos --- or 'takes' on 'the' Ubuntu logo.)

Consider 3D effects and animated GIFs. No Flash please. Let's keep it basic --- jpg's and/or animated gif's.

I have started collecting some candidates (of my own making or made by others) on an 'FE logos' web page.

For Contact information, see the 'Contact' page.

These pages are maintained on 9.10 Gnome2-Linux using a text editor, such as 'scite'.

But I may switch to a different Debian-based Linux 'distro' ---
such as Linux Mint MATE or Ubuntu MATE
--- as explained on the Contact page.

- NOTE -
The style of the font for the text in these web pages is not hard-coded.
This allows you to change the font style via a 'preferences' or 'tools' option in your web browser.
For example, in Seamonkey, use 'Edit > Preferences > Appearance > Fonts' and,
in the 'Fonts' panel, you can choose to change 'Proportional:' from 'Serif' to 'Sans Serif'.

You are given the Freedom to change the font for most of the text.
