Each chapter has a list of utilities discussed in that chapter.

For each command tryout at least one example provided in Chapter 5 of the Unix textbook. Feel free to use your own example. Show the screenshot for each commands output. Present your output in a tabular form with column 1 as index (1,2,3..), second column as the command, third as the usage, fourth as the screenshot of the output. You can just show a small snapshot for the output -- we do not need the entire screens image.
