Accepted Answer

500 computers

Question 14

In a scenario where a system administrator needs to monitor disk usage across multiple servers using command-line utilities, they decide to use the `du` command to summarize disk usage for a specific directory. The administrator runs the command `du -sh /var/log` and receives an output of `1.5G`. Later, they want to find out the total disk usage of all subdirectories within `/var/log` and decide to run `du -h /var/log/*`. What does the `-h` option do in this context, and how would the output differ if the `-s` option were used instead?

Accepted Answer

The `-h` option displays sizes in a human-readable format, while the `-s` option would summarize the total size of the specified directory only.

Question 15

In a scenario where a system administrator needs to monitor disk usage across multiple servers using command-line utilities, they decide to use the `du` command to identify which directories are consuming the most space. After running the command `du -sh /var/*`, the administrator notices that the output shows the sizes of directories in a human-readable format.
