I am totally new to linux [ 2 months ] and I get a little frustrated trying to open some files which are not deb, as the archieve manager easily installs these type files with out entering any commands, which I am very weak at. I know the apt-get install, update, upgrade, source, etc. but I get totally stuck on any download which has .sh on the end. I downloaded madusa4, which is a cad program I desperately need, and I followed the instructions until this one about superuser ( root ) which using the sudo command, I thought that identifies me as root.
Fedora yum install tcsh
Ubuntu sudo apt-get install csh
I did the csh install and that went as instructed. [ I do not trust my typing in what I see, so I use the copy / paste to avoid errors ]
Example 2: Installing MEDUSA
For the installation you have to be superuser (root). Open a terminal and run the file
