 Like the y options, there should be another option to skip the file
 without prompting,

 e.g. if we already have a file named test.mp4, then the current behavior
 of ffmpeg is to ask if one should overwrite the file or not, I suggest,
 there should be an options -N which will skip the file instead of
 overwriting without prompting for it.

 sample command line -

 ffmpeg -i '/home/de/media_writeit!/temp(others)/commercials/Banned
 Commercials - Funny - Bowling.mpeg' -vf scale='trunc((240*a)/2)*2:240'
 -threads 16 -b:v 400k -r 25 -vcodec libxvid -aq 6 -acodec libmp3lame

 File '/home/de/test.avi' already exists. Overwrite ? [y/N]

 I know the existing bash workarounds, but GUI frontends like ffmpeg can't
 do that.
