Permissions, Groups, and Users

The installation of all the perl components was not too difficult. It definitely helped that I used the completing filenames feature with the TAB key. That saved me some typing, but more importantly some unnecessary typos. I managed to create a new user group with a user account with all three applications. It was a relatively straightforward process in all three cases. The experience and knowledge I gained through each exercise, helped me in completing subsequent exercises. Reading, too, provided enough context that I was able to understand the steps I was taking. I went back to Arthur Griffith's Linux: Introduction to Linux, especially the chapter on Group and Shadow file, which helped my understanding of the assigned reading.

It was not too difficult to set up the new user groups and users in the CLI, but it would be too laborious and prone to error had the user permissions been set up on a larger scale. It seems also quite unnecessary as the GUI applications are very convenient to use and as far as I can tell they do their job well.

I needed to change file permissions occasionally in the past. I looked up the documentation and changed it. I still think I would use the command line for these ad hoc tasks. If, however, I would need to deal with permissions on a more regular bases I would choose a GUI application.
