Answer: B

Explanation:

The seq command in Linux is used to print a sequence of numbers, which can be piped to other commands or used in for loops and bash scripts1. The command can generate a list of integers or real numbers, with options to control the start, end, and increment of the sequence. The general syntax of the command is seq [options] specification1.

If you launch seq with a single number as a command-line parameter, it counts from one to that number. It then prints the numbers in the terminal window, one number per line2. For example, seq 10 will produce the following output:

1

2

3

4

5

6

7

8

9

10

Therefore, the correct answer is

B. The numbers 1 through 10 with one number per line.
