Redirect stdout and stderr to a file and also to console in linux

Question

I can redirect stdout and stderr to a file like below

some_command.sh >> file.txt 2>&1

Can someone let me know how can I redirect stdout and stderr to a file and also to console?

Answer 1

The tee command can help you out. It reads from standard input and writes to standard output and files.

So the following command will do:

some_command.sh 2>&1 | tee file.txt
