Answer 1

Command Line

To solve the question, we need an understanding of three commands that we use on the command line.

$\rule{320}{1}$

cat

The $\tt cat$ command is used to view files. It prints out the complete file.

So, $\texttt{cat sample.txt}$ will print out the complete file at once. If the file is long, you will be only able to see the last part, as much as possible, on your Terminal Screen.

more

The $\tt more$ command helps to view the text of a file one page (or one screen) at a time.

Looking at the question, this command is going to be useful.

man

The $\tt man$ command helps to view the "manual", or the help pages of some particular command.

For example, $\texttt{man cat}$ will show the help page of the $\tt cat$ command.

The Pipe Operator: |

The Pipe Operator (|) directs the output of the command on its left to the command on its right.

So, for example, $\tt ls|more$ will output the contents of the $\tt ls$ command one screen at a time.

$\rule{320}{1}$

The Answer:

It's clear that we need to use the $\tt cat$ as well as the $\tt more$ commands. They will be connected using the Pipe Operator (|).

So, the Answer is Option (B) $\texttt{cat sample.txt|more}$
