sauoq's solution is good if you know it will be at the end of the string. If you just want it to search from right to left, s/^(.*)ed/$1/i will work.

    Just thought I'd explain the previous regexes a little. The ^ represents the start of the string with $ represents the end of the string. The .* (greedy) part will match as many characters it can before 'ed'. On the other hand a .*? is non-greedy and will match as few as possible characters, in this case zero, before 'ed'. Also be sure to look at perldoc perlre. Hope this helps a little more.
