[Sheflug] command as argument for grep

["Chris Johnson" <chris [at] xxxxxxxxxxxxx>]

I have the following line

cat index.html |grep 'date %d-%b-%Y

which I thought would return all the lines in index.html that contained
today's date.  But it doesn't.  Can someone please remind me how to pass the
output of a command as an argument to a previous command.

Thanks

Chris Johnson
