Explanation / Answer

Answer#7. The 'uptime' command will give you the time elapsed since the last reboot. Additionally, it gives the following information:-

Current time, number of users logged in, load average.

The time elapsed is the second value which is displayed.

So a command that can be used for this is : uptime

  

Answer#8. Use the %s command.

The syntax of the %s command is :- %s/search string/replacement string/

Open the file baseball.txt in vi.

Then press Esc, followed by the colon (:) and then type %s/yankees/mets/ and press ENTER.

So the command is, :%s/yankees/mets/

Answer #9. Use the cut command eith -d and -f parameters for this. The -d parameter is used when we want to extract substrings based on some delimiter.

The -f parameter is used for field numbers to be extracted.

So, the command for this would be, cut -d ':' -f 1,6 /etc/passwd

This will extract the first field and the sixth field from each line of the /etc/passwd file, where the fields are separated by colons (:), giving the required result.

Unfortunately, linux refuses to load onto my system so I can't show you the screenshots of the results of these commands.

Hope this helps!
