The file shell-lesson-data/numbers.txt contains the following lines:
10
2
19
22
6
If we run sort on this file, the output is:
10
19
2
22
6
If we run sort -n on the same file, we get this instead:
2
6
10
19
22
Explain why -n has this effect.
-n option specifies a numerical rather than an alphanumerical sort.
