The Linux way of installing applications :
You have a ' Package Manager ' : "Add / Remove Software"
See it as a catalog with a selection of 15,000 packages :
Make a choice, click, and the package gets downloaded and
The command line tool for doing the install : 'yum'.
2) yum search <name> (or part of name)
2a) yum list available > available-packages.txt
... saves a text list in /home/"user-name"/
... with all available packages
4) yum install <package>
Good luck .. ..
