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

----------------
How can I remove software using the OS Linux. Now I tried to remove
Evolution also with purge. But it was not possible for me newbie. I
think it is the same problem like windows: I have to clean the hd from
Evolution. Is this right?
----------------
R = No, it's not right. Depending to your Distro, you can use many ways
to remove a software.
*
Thank You

To remove in Debian/Ubuntu:
* apt-get remove package (remove a package)
*
This was not ok.
* apt-get remove --purge package (remove a package and configuration files)
*
This was not ok.
* apt-get remove --purge --auto-remove package (remove a package,
configuration files and dependencies) To remove in RedHat/Fedora: *
yum remove package or yum erase package (remove a package and
configuration files)
*
Maybe this is ok:apt-get remove --purge --auto-remove evolution
Why:
After
apt-get remove --purge evolution
there were and there are a lot of directories filled with evolution files:

usr/lib
ussr/share
usr/share/gnome/help
usr/share/gnome/help-langpack
.config
.gconf
.local/share/evolution
(maybe more)

----------------
How to install a Linuxsoftware? Until now I open the Softwarecenter from
Xubuntu and then I start in a terminal: sudo apt-get install gimp. Where
ist Linux searching? On hd or in the www?
----------------
R = On HD. On terminal enter:
* gimp (you can use TAB to complete the command. You need the
grafic environment to execute the gimp)
* or on an grafic environment, click on the menus that appears on the
screen and search for the icon gimp
*
If there is a gimp on the live-cd I did sudo apt-get install gimp
and very often it is ok.
Sometimes the answer was: I miss files.

----------------
How can I install software not saved on the Live CD?
----------------
R = Yes, you can install software not saved on the Live CD, in the same
way that I showed above.
*
Example:
Can I try.
sudo apt-get freepascal
and then Linux is running through the www and bring me the freepascal?

Questions:
How many programs I can install with a Linuxsystem?
(for not block the os)

----------------
For example: Pascal compiler. And what kind of compiler: GNU Lazarus
Freepascal?
----------------
R = To search and display/show (caracteristics) a specific package to do
it:

To search in Debian/Ubuntu:
* apt-cache search expression (for example: "apt-cache search pascal".
Many generic)
* apt-cache search expression | grep -i expression (for example:
"apt-cache search pascal | grep -i pascal". More cool and specific) To
search in RedHat/Fedora:
* yum search expression (for example: yum search pascal)
* yum list package
To show package caracterists in Debian/Ubuntu:
* apt-cache show package To show package caracterists in RedHat/Fedora:
* yum info package
*
Sorry, this was the right question.
How can I find the best "pascal-compiler"?
I was reading newspapers and forums to find out. OH gimp blender
inkscape are the best graphik software for me.
Because when I open softwarecenter, there are a lot of software for draw
pictures.
Same I was trying and looking aroung to see claws is the best email
programf for me.

I hope I helped you,
