> cat file | sed "s/<div>/<p>/g" | sed "s/<\/div>/<\/p>/g" > newfile
sed "s/<div>/<p>/g" file | sed "s,</div>,</p>,g" > newfile
(one sed, two regexps)
sed -e "s/<div>/<p>/g" -e "s,</div>,</p>,g" file > newfile
(only one regexp)
sed "s,<\(/\?\)div>,<\1p>,g" file > newfile
(shown only for the last one, but it can be used for any,
change in place)
sed -i "s,<\(/\?\)div>,<\1p>,g" file
in that case the file "file" is changed, non new file is created.
