1. How many files exist on the system that have the “.log” file extension?

To find the files we use the find command.

find / -type f -name *.log 2>/dev/null | wc -l

Where wc -l will count the output lines.

Answer: 32

2. How many total packages are installed on the target system?

To perform this task we will take help from apt which is a package manager in Linux.

apt list --installed | grep -c "installed"

The command grep -c counts only the lines which contain the word ‘installed’.

Answer: 737
