Do you want to run that command in the shell? This pipes the output of
'echo' (with no parameters: just prints a single newline) to date (with
no params, ignores its input anyway) and redirects the output of date
into date.txt .

System doesn't do that . chan_backticks does:

But then again, I figure that there's a simpler way.
