To check where a symlink points, use
ls -l symlink
where symlink is the link you want to check. Try to remember l for link (-l).
To create a symlink, use
ln -s /path to/file /path to/symlink
Try to remember ln for link, s for symlink, and DESTINATION <- LINK for the order.
To change an existing link, it’s the same thing, except you say
ln -fs
The f stands for force (think of forcing a change).
When compiling from source, you may eventually try
sudo ./configure && make && make install
However, it may cause a problem on the install step, saying it can’t create whatever, permission denied. The solution is quite simple:
./configure
make
sudo make install

Follow the instructions here exactly. Important to note is that you must run & use scangearmp to use the scanner. Simple Scan doesn’t work. Scan Gear gives you the usual options you see when you scan on Windows (dpi, paper size, image settings, preview, etc.).
dpkg -s packagename
where packagename is, obviously, the exact package you want to look up. Info includes other useful data like dependencies, architecture, description, etc.
