HEREDOC for Windows Batch Files

From Wikipedia: "In computer science, a here document (here-document, heredoc, hereis, here-string or here-script) is a file literal or input stream literal: it is a section of a source code file that is treated as if it were a separate file."


Here's one way to accomplish this in a Windows batch file. Inside the batch file, echo the text to an output redirection, e.g. "> here.txt". Use carets "^" followed by double linebreaks to output on separate lines:

here_test.bat

echo This is my ^

multi-line here document ^

that this batch file ^

will print! > here.txt



When executed here_text.bat will create a new file here.txt containing the lines of text:

This is my
multi-line here document
that this batch file
will print!

Protective

Noticed this rather defensive SSID in passing from my bus commute. I'm not sure if it's the WiFi or the Wife that's under guard, but the security's pretty robust.
