Software in Ubuntu can be installed through the Software center of the graphical interface, or via the command line Apt-get install. But where is the installed software? This is not the same as the path selection for installing software in a Windows environment. Most of the terminals available in Ubuntu are/usr/bin or/opt, but not necessarily. Try to find the location of the software quickly using the following method.
1. Implementation of the procedure;
2. Use the command ps-e to find the name of the program;
3. Find the file location using the Find or Whereis command.
In addition, if you know the software installed using the Apt-get Install command, you can use the command dpkg-s softwarename to display all locations containing this package, Dpkg-l softwarename display the installation path.
Ps:
Aptitude show Softearename or dpkg-l softwarename view software version
