Does anyone know if we can use command substitution in sed?
For example, I want to replace a line of text in a file
where date is the output of the date command.
Thanks,
John

here are several solutions that will work:
BTW, the following does not work as you probably found out:
That's because of what doesn't happen inside single quotes.
read the man page for your shell and concentrate on the quoting
aspects.

#note the quotes around the sed argument...they allow the shell to
expand the $DATE variable.
