Re: Troubleshoot recipe to prevent repeating footer

Jo asked,

To make it work for exactly a one-line footer, sure:

 TEXT=`cat footer.txt`

but to make it look for the second line of a file with two or more lines but
the only line in a one-line file would be nasty in sed.  Pick your poison:

 TEXT=`sed -e\$q -e1d -eq footer.txt`
or
 TEXT=`sed -e2q -e\$q -ed footer.txt`

Another way to deal with a one-line footer is to add a blank line above it so
that it now is a two-line footer (with a blank first line).
