I am wondering what sudo apt-get update does?
What does it update?
Do you have any idea how to extract a part of a PDF document and save it as PDF? On OS X it is absolutely trivial by using Preview. I tried PDF editor and other programs but to no avail.
I would like a program where I select the part that I want and then save it as a PDF file with a simple command like CMD+N on OS X. I want the extracted part to be saved as PDF and not as JPEG, etc.
I've searched the net for such information and found different command lines, like these ones:
sudo apt-get remove application
sudo apt-get remove application*
sudo apt-get remove --purge application
sudo apt-get remove --purge application*
sudo apt-get purge application
sudo apt-get purge application*
So, what is the correct way? Is it necessary to use that "*"?
After that, I also found these commands:
sudo updatedb
sudo locate application
sudo rm -rf (file/folder name)
I would like the user to have full rights on this folder (as well as all sub-directories and files in it):
~/.blabla
currently owned by root.
I have found numerous posts (in this forum and elsewhere) on how to do this for files but I can't find a way to do it for whole folders.
How can I run scripts automatically when Ubuntu starts up so I don't have to run them manually after startup?
