Yup, much better. Although it seems the p command has to be in the
second -e.

Just by the bye, here is my code for extracting the 20 characters

a="$( sed -n -e 's/.*foo="\(.\{20\}\)".*/\1/' \
-e "s/'/''/gp" \
$1 \
| head -n 1 \
)"

Hmm... hadn't considered that. So this script will probably not work if there is no enclosed apostrophe. :(

Might have to go with:
a="$( sed -n -e 's/.*foo="\(.\{20\}\)".*/\1/p' $1 \
| sed -e "s/'/''/g" \
| head -n 1 \
)"
