Description: Two problems with the video:
1) At about 1:23-mark, the narrator is discussing the "-h" option for "df" and "du" commands (note lower-case) and he says it displays in units of kilobytes, megabytes, and gigabytes, which are the names of the SI units (10^x exponent-wise). "-h" actually displays in kibibytes, mebibytes, and gibibytes, which are the 2^x units. "-H" displays the SI units. The textbook's text below the video gets this right, but the video needs to match the text.
2) At about the 1:55-mark, the narrator is discussing the output of the "du -h /var/log" command and he says it "lists all files." Based on that description, one would expect to see, for example, /var/log/messages in the output, but that file isn't displayed. In fact, "du" only lists directories in its output, but ultimately shows the size of all files in those directories. Again, the textbook's text below the video correctly alludes to the fact that the "du" command displays "the space used by a certain directory tree." The video should make clear that the output of "du" is only displaying directories, but the size values for each of those directories accounts for all of the files in those directories.
