In this video I've removed all the images taken between 8pm and 5am. Don't worry, I didn't have to do this by hand! All the videos save with a similar file name which has the date and time in it so I wrote a little regular expression that deleted all the files with a 00 - 04 or a 20 - 23 in the hour slot. The commands looked like this:
rm 00A8F9005FCC\(IPCamera\)_0_2013????0{0..4}*
rm 00A8F9005FCC\(IPCamera\)_0_2013????{20..23}*
The rm command you should be familiar with, then it is the camera's MAC address (I think) followed by the name in brackets then _0_ (for some reason, maybe camera number) then the 4 digit year, 2 digit month (single digit wildcards), 2 digit date (single digit wildcards) then the 2 digit hour. Notice in the first command I put the first digit of the hour outside the curly bracket, I just wasn't sure 00..04 would work so opted for 0..4 instead. What came after the hour digits didn't matter so I just dropped in a multi digit wildcard.
