Hello, I need some help regarding this question. Thank you.

What does the following command do: sort file1 file2 O Creates a sorted output consisting of the lines from file1 and file2, merged together in ASCII order. The output is displayed on the screen. Creates an error message. O file1 and file2 create a file called sort. The input of file1 is piped to file sort, creating file2. This command only works in the korn and C shell
