The echo command is used to print a statement by default to the screen.
example:
echo Good Morning
output:
Good Morning
note: quotes are not used and will be displayed in the output if used
other examples:
echo off/on - turns echo on or off, otherwise commands are visible
on the screen. Useful for bat files.
@echo off - the @ hides the line it precedes so use this for the first line.
echo. - displays a blank line
echo text > myfile.txt - writes to target location (myfile.txt), overwiting it if it exists.
echo text >> myfile.txt - appends to the target (myfile.txt)

What are the file commands of DOS?
Use the "dir" command (without the quotes) to see all files in the current directory. Use the "type" command (Just like before, no quotation marks.) followed by a file you want to look at to see the file's contents. Use the "echo" command (Okay, I think you get the point about the quotation marks now.) to print something to the screen. Not very useful. Is it? You can use the "echo" command to overwrite files too! For example, "echo Hello >> a.txt" will overwrite a.txt with the text "Hello." If a.txt does not exist, the echo command will create one.
