Unix command of the day: Tee April 2015

The tee command allow you to write to a file and still display the result in output.

For exemple

ls

display the content of the current folder in stdout (the terminal)

ls > file.txt

saves that in a file file.txt

ls | tee file.txt

saves that in a file file.txt and displays in stdout at the same time

Well done! You've reached the end of my post. Now you can leave me a comment :)
