In sed, you don't have to use "/" to separate your statement.
sed 's/this/that/g' is the same as sed 's#this#that#g'.

+!How can I EDIT a file using sed?
+
+Use the ''-i'' switch.
+This means that the file you supply to sed is overwritten with the changes made by sed.
+If you don't want to lose the original file then after the ''-i'' switch you can add a backup extension.
+
+For example:
+
+*sed -i.bkp '1,2d' test.txt
+
+This will edit test.txt and the original file can be found in test.txt.bkp
