Linux Command Fun Facts!

Did you know that Linux has some interesting command options?

Which of the following commands will display the contents of a file in reverse order?

a - cat filename | rev

b - cat -r filename

c - rev filename

d - None of the above

Answer:

The correct command to display the contents of a file in reverse order is option a - cat filename | rev.

When it comes to manipulating data and files in Linux, there are some fun and interesting commands that you can use. One of them is the "rev" command, which reverses the lines in a file. However, if you want to display the entire contents of a file in reverse order, you can combine it with the "cat" command using the pipe symbol (|).

So, by running "cat filename | rev", you can see the contents of the file displayed in reverse order. This can be a fun way to explore the contents of a file in a different perspective!
