Exam 101-400 topic 3 question 12 discussion

The command that will send output from the program `myapp` to both standard output (stdout) and the file `file1.log` is: D. `myapp | tee file1.log` The `tee` command is used to read from standard input and write to standard output and files. In this case, it takes the output of `myapp` and both displays it on the terminal and writes it to the file `file1.log`.

The tee command, used with a pipe, reads standard input, then writes the output of a program to standard output and simultaneously copies it into the specified file or files. Use the tee command to view your output immediately and at the same time, store it for future use.

I think option 'c' would also be valid. He tried it and does the same.
