Fixed that, thanks.

That was my original idea, but I'm not certain on how to properly store the results from find and then safely delete them all (accounting for weird filename characters, etc).

*edit* I had looked at this, and it looks a bit wild to me.

So maybe if you want to avoid the double find call, this is a safe way:

Code:

readarray -d '' files < <(find $DIR -type f -maxdepth 1 -name "*.avi" -size -6M -print0)
printf '%s\n' "${files[@]}"

read -p "Really delete all? " -n 1 -r
echo
if [[ $REPLY =~ ^[Yy]$ ]]; then
  rm -i "${files[@]}"
fi

This is specific to bash (>= 4.4), so -current only. Seems to work with strange characters in filenames, I'd test this though, hence the "rm -i" bit. Other people might know better ways though, I'm just looking at this for fun

Thanks everyone, for all the suggestions.

Usually when I wake up and maybe once or twice throughout the day I'll go into the directory that has all the videos that caught 'motion' and look at them.

The videos that are 4MB and smaller usually will be a car going by relatively quickly (figure 5-10 mph, no faster as this is a trailer park and the main road runs right down the middle of us all, heh).

Other things like a cat or bird or bug, or a kid or two running to the bus stop, all usually are pretty quick and make a file of 4MB or smaller.

Anything larger I want to watch in MPlayer or whatever to make sure it isn't something that happened I want to know about or at least have the video to use as 'proof', etc.

So I've gone ahead and forgone the need to check anything 4MB and smaller and just use the first good script we came up with in this thread. If I let things go without checking for, let's say, 6 hours, there will be around 20-30 files and probably 10%-20% will be those I can delete without worry of looking at them. It takes time to watch what's leftover, if you figure a 9MB file lasts approximately 20 or 30 seconds and I have 20 to look through, heh.
