h4xx0ri5e is a service menu which renames files to give them a more hackerish look.
hacker -> h4xx0r
hack -> h4xx
the -> teh
a, A -> 4
l, L -> 1
o, O -> 0
s, S -> 5
Hope you may have fun with it.
just copy (i assume you've got kde in the standard place):
h4xx0r15e.desktop to ~/.kde/share/apps/konqueror/servicemenus (for yourself), or
to /usr/share/apps/konqueror/servicemenus/ (for everyone), and
h4xx0r15e.sh to one of the $PATH directories, f.ex. /usr/local/bin, or /usr/bin
doesn't work with filenames with spaces. sorry, i just don't feel like trying to fix it now since i know the whole thing is useless and pure fun, anyway.
