Note

There are no wrong answers. This is for participation credit, and is intended to let me know how well we understand the material at this point.

Question 1

You created a text file in your current directory with your analysis, and named it (incorrectly / misspelled) as analyis.txt.

What command could you use to give the file the correct spelling (analysis.txt)?

Question 2

The cat command can concatenate files. That is, if you have files begin.txt and end.txt representing two halves of a dataset, you can concatenate them (display one after another) by doing:

cat begin.txt end.txt

Suppose you wanted to create a file called whole.txt that has the two halves together in the single file. How do you think you could use cat to create this while.txt file?

Question 3

Imagine you have the following files:

hello
hello.cpp
hello.H
main
main.cpp

Using the wildcards we learned, what pattern would match just the files hello.cpp and hello.H?
