batch-file – Echo outputs everything literally

Quotes will be output as-is:

echo "Some Text"
"Some Text"

Comment tokens are ignored:

echo Hello World REM this is not a comment because it is being echoed!
Hello World REM this is not a comment because it is being echoed!

However, echo will still output variables – see Variable Usage – and special characters still take effect:

echo hello && echo world
hello
world
