echo $LINES | sed 's/á/a/g' | sed 's/Á/A/g' | sed 's/é/e/g' | sed 's/É/E/g' | sed 's/í/i/g' | sed 's/Í/I/g' | sed 's/ó/o/g' | sed 's/Ó/O/g' | sed 's/ú/u/g' | sed 's/Ú/U/g' | sed 's/ñ/n/g' | sed 's/Ñ/N/g' | sed 's/ü/u/g' | sed 's/Ü/U/g'

exit 0

Why not:

echo $LINES | sed -e 's/à/a/g' -e 's/Á/A/g'  . . .  -e 's/Ü/U/g'

and so on?

Or:

sed -e "s/\./ /g; . . . ;s/-/ /g;s/)//g"
