Good morning
Problem 2:Install Remove Software
Thank You for help.

* apt-get remove package
* apt-get remove --purge package

* apt-get remove --purge --auto-remove package
--------------
This was not ok.
--------------

Sophie, in the above commands replace the word "package" by the name of
the package you want. For example, to remove the command called "less" do:
* apt-get remove less
* apt-get remove --purge less
* apt-get remove --purge --auto-remove less
In your case, the package is the "evolution".
*
Is it:
* apt-get remove evolution
* apt-get remove --purge evolution

* apt-get remove --purge --auto-remove evolution

And the last line is cleaning the whole hd from evolution, isnt it?

---------------
apt-get remove --purge evolution
there were and there are a lot of directories filled with evolution files:
---------------
Yes, because the "evolution" is a graphic software and requires many
files, libs and integration with the desktop environment to work. You
could do this (thus avoiding remove many files):
apt-get remove evolution
*
I did "apt-get remove evolution" and after this remove, there are a lot
of "evolution" files.
Is it simlar to win? If You delete software in a win-system, afterwords
You have a lot to clean for example the registry.

----------------
Example:
Can I try.
sudo apt-get freepascal
and then Linux is running through the www and bring me the freepascal?
-----------------
Use this "apt-get install freepascal" or this "apt-get install fpc"
There is another pascal compiler called "gpc" (GNU project) - Very good,
by the way. Do it:
"apt-get install gpc"
*
What pascal-compiler is the best?
Lazarus
Freepascal
GNU
?
Lararus is a GUI, but is Lazarus also a compiler?

---------------
Questions:
How many programs I can install with a Linuxsystem?
(for not block the os)
---------------
The Linux (as a Debian, Ubuntu, Fedora, CentOS, ...) has no such
limitation. In this case, the limitation is the hardware employed (eg:
HD, Memory, ...).
*
I can see the hd. If there a 20 gb space, then there is no problem?
How can software or to many software-programes block the memory?

-------------------
How can I find the best "pascal-compiler"?
------------------
First, check the pascal compiler that exist on your Linux. The comand
for this is:
apt-cache search pascal (many compilers will appear as "fpc", "gpc",...)

For show information package, do this:
apt-cache show fpc ou apt-cache show gpc

The best pascal compiler depend on what you need or want. I used the
"gpc", because the "gpc" is done by the GNU Project (philosophical
questions).
*
I want to write programs like this
programm a; var a:inter; begin read(a); write (a); end.
Text and very simple. So I think, Freepascal or GNU are better then
Lazarus,isnt it?

Sophie
