!Extremely handy hint 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
