First of all, congratulate yourself for having learned how to download and
install this particular software WITHOUT using the package manager. It's
really powerful that you can do that; it's a cool thing you can do
HOWEVER The downside is when you ran that build.tk file, it installed the
software on your system and the package manager does not know where it is.
That's why apt-get (or if you had used Synaptic or the Ubuntu Software
Center) didn't find it. The package manager makes things really easy -- not
only does it know where things are, it knows how to make sure everything
NOW THE SCARY PART: ... do you TRUST the programmers who wrote that
software? Can you TRUST the location you downloaded it from? As soon as
you ran that build program, it COULD have gone through your machine doing
all sorts of things to your computer. If you were somewhat cautious and
never gave it your system password, then it wouldn't be able to do anything
worse than destroy or give others access to all of the data files you can
access from your computer. If you DID give it your system password, then it
could destroy or give others access to your entire system and possibly
other places in your network. You didn't give it a password did you?
(Actually I am sure you did, because I looked ahead and I know the script
needed it to work.)
SO let's assume you CAN trust the folks who wrote that software you
I downloaded the software myself and had a look.
The wish command is just a shell for running Tcl program files. build.tk is
a tcl program file.
Open that file and have a look inside it -- you can see the commands it ran.
Notice at the very top, it includes a setting that defines "INST_DIR" --
It also defined MAN_DIR (online help files) -- /usr/local/man
SO those are the places where it PROBABLY installed its files. (assuming
you can trust the programmers, remember?)
If you have not done a "local install" of any other software, this will be
the only stuff in those two directories, and it will be really easy to
delete it. Just delete everything INSIDE /usr/local/bin/ and
/usr/local/man/ (do not delete the "parent" directories).
If you don't know how to delete stuff in those directories, I bet you can
figure it out.
In a terminal:
-- the delete command is called rm
-- the command to temporarily give yourself root permission is sudo
-- the command to learn how to use those commands is called man
so for example: type
OR once you know a command and just want a reminder
if that last one scrolls off the screen, learn about "pipes" and the less
rm --help | less
That last set of commands tells the rm program to display its help files
and "pipe" the output to the less program so you can read it comfortably.
NOW you have great power, and with great power you have great
responsibility. Use it wisely!!!
