[amp_mcq option1=”SORT > filename” option2=”SORT < filename" option3="SORT/R < filename" option4="SORT/V < filename E. None of the above" correct="option3"]
The correct answer is C. SORT/R < filename.
The SORT command is used to sort lines of text in a file. The /R switch tells SORT to sort the lines in reverse order. The < filename switch tells SORT to read the input from the file filename.
For example, if you have a file called list.txt that contains the following lines:
1
2
3
4
5
You can use the following command to sort the lines in reverse order:
SORT /R < list.txt
This will produce the following output:
5
4
3
2
1
The other options are incorrect. Option A, SORT > filename, will overwrite the file filename with the sorted output. Option B, SORT < filename, will read the input from the standard input device (usually the keyboard). Option D, SORT/V < filename, will sort the lines in case-sensitive order. Option E, None of the above, is also incorrect.
