This is the file I tried to open,
However I did install the program on my Arch set up and it seems to work really well for the few compressed archives I tried it on.
The article I found was here at nixCraft
which led me to the developers page,
With this little tool you can extract almost any archive in Linux so you do not need to remember which tool and what command lines are necessary.
I got fed up with the sheer impossible number of compression formats out there. I am an avid linux command line user, but remembering 20 different commands with strange switches to get to the juicy content of a compressed files is too much for me.
Therefore I have just happily spent a few hours of my life to write the application e that identifies which extraction tool to call with what parameter in order to save me precious seconds of rereading forgotten manpages.
I was also inspired by the ugliness of the tool unp which tries to do exactly what e does. I did not like the implementation (written in Perl), and thought I can have the same features in a much simpler and more extensible way. The result is that e is just about 80 lines of code, where most of it is either comment or rules that define when to call what.
Just another oddity brought to you by by my curiosity for the esoteric.
