how to echo whole string to a file?


Is there anyone know how to echo whole string to a file?

I am trying to echo the below sting into a file, but the output will be DATETIME=070620115242

DATETIME=`date +"%y%m%d%H%M%S"`

Appreciate someone can help on this : )

Use the redirection operators > or >>. The latter will append to a file while the first will overwrite its contents:

DATETIME=`date +"%y%m%d%H%M%S"`
echo DATETIME=$DATETIME > file.txt

It still occurs the same output in the file "DATETIME=070620121353"

I need the below exact line exist in the file.
DATETIME=`date +"%y%m%d%H%M%S"`

Is there any way to do it?

btw, "echo -n > filename" will empty the file.
