The **`tee` command** in Linux reads the standard input and writes it to one or more files, along with the standard output.

## Code

In the code below, we use the `tee` command to redirect the output of the `echo` command to the file as well as to the terminal. Then, we use the `grep` command to check if the file is created. Finally, we print the contents of the file created by the `tee` command.

echo "hello-educative" | tee file.txt
echo "-----"
ls -l | grep file
echo "-----"
cat file.txt
