A Systems Administrator Downloads an Application's Source Files, Compiles the Application

A systems administrator downloads an application's source files, compiles the application, and installs it per the application's installation instructions. When trying to run the application, the system states: $ occmd bash: occmd: command not found… Running the locate command shows it does exist in the following location: /opt/occmd/bin/occmd Which of the following should the administrator do to allow the command to run properly? (Choose two.)

A) sudo ln -s /opt/occmd/bin/occmd /usr/local/bin/occmd
B) echo "export PATH=$PATH:/opt/occmd/bin" >> ~/.bashrc
C) mv /opt/occmd ~/ && ln -s ~/occmd/bin/occmd ./occmd
D) echo "#!/bin/bash \n ${which occmd}" > /usr/bin/occmd.sh
E) sudo mv /opt/occmd/bin/occmd /etc/bin/
