Ubuntu :: LibUSB - How To Check If It Is Installed
Jun 1, 2011
I'm trying to install libusb. I've downloaded a file from [URL]. I've unzipped the file; the folder's on my desktop. I've tried to install this, but I'm not sure how. Under installation it says: See the file 'INSTALL'. There are a few files that start with this term: INSTALL.libusb, INSTALL.libusb.in and install-sh. The first two appear to be the same, while the latter appears to be some sort of program.
When I double click it, I get a few options, including "run". I assumed this was the correct way to install the program, but when I hit run, nothing happens. I've displayed this file, but this gives me no additional information. I've tried running it in terminal: nothing. Maybe it has installed, and I just don't know it. How would I even check if it's installed? (I'm only installing libusb because I need it for something else).

I got Fedora core release 3
kernel 2.6.9-.667
I would like to know which command I have to use to see the libusb installed. I used this:
yum list installed | grep usb
but no output.

How do check the programs that the actual user of the computer installed. I do not care at all about the default programs that came with your distro of Linux, I only want the user installed programs.

Let's say that I've installed the following versions of R on my computer.
R 2.10

Is there a bash command which can be used to getst of all versions which are installed.I've used dpkg --get-selections | grep r-base but that just return 'r-base' and i'd have no info on the version.

I've just installed ubuntu 9.04 (had the disc from before) and I'm upgrading to 9.10 of course but I have a question. How do I check that I have the latest drivers installed for everything in my laptop? I'm the kind of person that has that nagging feeling in the back of my head telling me that everything isn't installed perfectly and I need to install my drivers properly (or at least ask).

I know with if statements in bash you can do
Code:
if [ $fruit = apple ]
then echo "Good, I like Apples"
fi
But I was wondering if you could do something like this:
Code:
if [apt-cache pkgnames smbfs = smbfs doesn't exist]
the apt-get install smbfs
fi
If so how would you capture the output from apt-cache pkgname smbfs to determine if it's installed?

After sifting through numerous apt-get apt-cache apt-file tutorials I still can't find a command to check if a package is installed via the terminal command/line.
I know there must be some way to do it.
Say I want to check if any package from the libavcodec*.deb family is installed how could I do this without a gui eg synaptic?

I'd love to know how to check the original configuration of a self-installed package? For example, I would like to install the package XXXXX. I did:
./configure
make
make install
After the installation, I would like to know what the configuration I used for XXXXX's installation. Maybe some dependencies (for example, A,B,C...) were not found so that XXXXX was installed without depending on A,B,C.... However, now, I would like XXXXX depend on A,B,C... How to check whether the current installed XXXXX's original configuration?
