Every time I use a new computer I try to configure the computer so that it is as similar to the interface I am used to as it can be. Setting up a different view in the MS Windows Explorer is one of the first things I do, I set up the Explorer to the 'Details' view, then I enable the display of file extensions and hidden files. I am glad that I learned about the alias, or rather how surprisingly easy it is to create one and how powerful a short cut an alias can be.
When configuring a computer it is important to recognize whether the change happens on the level of a single user or on system level for all users. In Ubuntu this difference is reflected in using 'sudo' in combination with the regular Linux command. I modified a 'ls' command so that it would display by default the hidden files, as well. I created an alias for 'ls' to behave as 'ls -a', this should happen on the level of a single user, so I did not need to use 'sudo', while in the exercise that enabled a look-up for third-party supported applications for Ubuntu this change happens on the level of system for all users and 'sudo' had to be used. I forgot to use 'sudo' first when opening the appropriate file, and only the read copy thereof opened.
I did not use nano for the exercises this week. The interface resembled pico and since I have been using vi for some time, I stuck with it mainly because I find vi more responsive and faster. I usually learn by reading a book, and some material that makes sense and/or I use in my work I will remember, but most of what I learn I forget. However, I am glad I have to opportunity to work on all those tutorials, and the material makes more sense to me now.
