Batch file append text new line

A simple but useful question!

To append text to a file and add a new line in a batch file, you can use the following syntax:

echo. >> file.txt
echo Your new text here >> file.txt

Here's what's happening:

• echo. is used to add a blank line to the file. The dot (.) is a special character in batch files that represents a space, and the echo command will print it followed by a newline character (\n).
• >> file.txt redirects the output of the echo command to the file file.txt, appending to the end of the file instead of overwriting it.

So, when you run these two lines, the file file.txt will be created or updated with the following contents:

Your new text here

If you want to add multiple lines of text, you can repeat the echo command with the desired text:

echo. >> file.txt
echo Your new text here >> file.txt
echo Another line of text >> file.txt

This will result in the following contents in the file:

Your new text here
Another line of text

Note that if you want to add a literal newline character (\n) to the file, you can use the following syntax:

echo Your new text here^& >> file.txt

The ^& is an escape sequence that tells the batch file to treat the newline character as a literal character instead of a command separator.
