Subject: Re: Looping through files using exec

You said bash...

Does "Done" represent a directory?  and.. does Done\#{filename} work
with this option? I would have thought that in *nix, it would be
Done/#{filename}

Not exactly sure what this app is supposed to do but the loop looks ok..

irb(main):004:0> puts "mencoder \"" + x + "\" -vf scale=320:240 -ovc
lavc -lavcopts vcodec=mpeg4:vbitrate=150 -oac mp3lame -lameopts
vbr=3:br=64 -o \"Done\\" + x + "\""
mencoder "pron.avi" -vf scale=320:240 -ovc lavc -lavcopts
vcodec=mpeg4:vbitrate=150 -oac mp3lame -lameopts vbr=3:br=64 -o
"Done\pron.avi"
