You may be familiar with using 'vi'...in which case you can open a file using vi...manipulate as required then save the changes and you have amended the file.
You can actually do this both from the command line or using 'vi' or another editor like ed. From the command line you will have to direct output to another file and then rename the file back....this code would do it for you...
sed -e 's/$/,/g' -e '$ s/,$//' your_file > new_file && mv new_file your_file
