Comprehensive List of Mtee Commands with Descriptions

**Mtee** is a command-line utility that allows you to tee (duplicate) the output of a command to multiple destinations, such as files and the console, simultaneously. Below is a detailed list of Mtee commands, along with descriptions and examples.

---

1. Basic Output to File and Console
Description: Redirects the output of a command to both a file and the console.

Code:

command | mtee [OutputFile]

Example: To list directory contents and save the output to `output.txt` while displaying it in the console:

Code:

dir | mtee output.txt

2. Append Output to a File
Description: Appends the output of a command to an existing file rather than overwriting it.

Code:

command | mtee -a [OutputFile]

Example: To append the output of a directory listing to `output.txt`:

Code:

dir | mtee -a output.txt

3. Suppress Output to Console
Description: Redirects the output of a command to a file while suppressing the output to the console.

Code:

command | mtee -q [OutputFile]

Example: To save the output of `dir` to `output.txt` without displaying it in the console:

Code:

dir | mtee -q output.txt

4. Writing Output to Multiple Files
Description: Redirects the output of a command to multiple files simultaneously.

Code:

command | mtee [OutputFile1] [OutputFile2]

Example: To save the output of `dir` to both `output1.txt` and `output2.txt`:

Code:

dir | mtee output1.txt output2.txt

5. Redirecting Output and Error Streams to Different Files
Description: Redirects standard output and standard error streams to different files.

Code:

command 1> [OutputFile] 2> [ErrorFile]

Example: To save standard output to `output.txt` and errors to `error.txt`:

Code:

dir 1> output.txt 2> error.txt

6. Combining Output and Error Streams
Description: Combines both standard output and standard error streams and writes them to a single file.

Code:

command 2>&1 | mtee [OutputFile]

Example: To save both standard output and errors to `output.txt`:

Code:

dir 2>&1 | mtee output.txt

7. Using Mtee with a Delayed Command Execution
Description: Delays the execution of a command and redirects the output to a file.

Code:

timeout /t [Seconds] >nul & command | mtee [OutputFile]

Example: To wait for 5 seconds before listing the directory contents and saving the output to `output.txt`:

Code:

timeout /t 5 >nul & dir | mtee output.txt

8. Piping Output Through Multiple Commands
Description: Pipes the output of a command through multiple commands, with Mtee capturing the final output.

Code:

command1 | command2 | mtee [OutputFile]

Example: To list directory contents, filter for `.txt` files, and save the output to `output.txt`:

Code:

dir | findstr ".txt" | mtee output.txt

9. Redirecting Input from a File
Description: Uses Mtee to process the contents of a file through a command.

Code:

type [InputFile] | command | mtee [OutputFile]

Example: To display the contents of `input.txt`, process it, and save the output to `output.txt`:

Code:

type input.txt | findstr "search_string" | mtee output.txt

10. Logging Output with Timestamping
Description: Logs command output to a file with a timestamp for each entry.

Code:

command | mtee -t [OutputFile]

Example: To log the output of a command with timestamps to `log.txt`:

Code:

dir | mtee -t log.txt

11. Displaying Help Information
Description: Displays help information for the Mtee command, listing all available options and their descriptions.

Code:

mtee -?

Example: To display help information for Mtee:

Code:

mtee -?
