To sort things in descending order using the sort command, you can use the -r option.
Step-by-step explanation:
To sort things in descending order using the sort command, you can use the -r option. This option stands for 'reverse' and it will reverse the order of the sort, putting the items in descending order instead of ascending.

sort -r numbers.txt
