You were, you just didn't know: kate was helpfully doing that for you :) As Greg explains in another post, what happens is that crontab invokes an editor and waits until that process returns. Then it "knows" you are done editing, picks up the modified file and installs it in place. Kate (without the -b option) breaks that expectation by returning immediately (crontab "thinks" you are done) and continuing "in the background" (from the POV of crontab) letting you edit the file. At that point in time, crontab has already picked up the (yet unmodified) file. Any modifications you may make are lost, since too late. Cheers -- t
