After installing a new application, how do you launch it? As with most things in Linux there are many ways to accomplish the same goal.

From the file list in KPackage, we know the application was installed into the /usr/bin directory.

To find this folder, open a file manager window and click the "Root" folder (or hit the "up" arrow) to take you to the top-most level.

Then select "usr", then "bin" and scroll down this long list until you see the "ktail" executable file. Click it once to launch the program.
