Objective

The objective is to remove all orphaned packages from CentOS Linux. By orphaned packages we mean all packages which no longer serve a purpose of package dependencies.

For example, package A is depended on package B, thus, in order to install package A the package B must also be installed. Once the package A is removed the package B might still be installed, hence the package B is now orphaned package.

Gorilla Password safe application is not part of CentOS/Redhat 7 package repository and thus it needs to be installed manually on your Linux system. First, let's take care of the prerequisites. Here we assume that you have already enabled EPEL repository: 
# yum install tcllib tk itcl git
In the next step we are going to clone a current Gorilla Password repository using git command: 
$ cd /tmp/
$ git clone https://github.com/zdia/gorilla.git
Once we get Gorilla Password sources cloned locally we can copy them into a designated directory/opt: 
# cp -r gorilla/sources/ /opt/gorilla
