[SOLVED]cp not overwrite but rename

XenoZergNid · 2014-01-23 19:19:49

so I'm creating some bash scripts for controlling my camera and it creates a file called Capture.jpg. because I need the files in a seperate folder and in order(so the can easily be compiled into my stopmotion) I would like to copy the file into the other folder as Capture1.jpg then Capture2.jpg then Capture3.jpg...
how would I do this?

Post the script in question.
I guess you first create Capture.jpg and then rename it to Capture0000.jpg, next one will get renamed to Capture0001.jpg etc.

well that will work, the only problem is that I don't know how to store the number it will be renamed too. heres the script:

#captures the image from the camera to the file
capture 'capture Capture.jpg'
#copy the file to the new file. how should I get the right number?
cp './Capture.jpg' './pictures/pic'1'.jpg'
#for onion skinning; isn't related to this problem
capture 'vfalign transparent ./Capture.jpg'
exit 0

man date

If you're going to call this script by hand only a few times, you can enter the number yourself.
Is it going to be called automatically e.g. every 5 seconds or ...?
You can simply use the date and time (with seconds) as the directory name.

@Karol
The stopmotion will be 15 fps so a 30 second film will be 450 pictures.
@jasonwryan
how would I write that line?(I'm relativly new to bash script)
cp './Capture.jpg' './pictures/pic' how do I write the output of date +"%d-%M-%S" here? '.jpg'

karol · 2014-01-23 20:18:02

$ touch capture.jpg
$ cp capture.jpg capture-$(date "+%s").jpg
$ cp capture.jpg capture-$(date "+%s").jpg
$ cp capture.jpg capture-$(date "+%s").jpg
$ ls
capture-1390508060.jpg	capture-1390508064.jpg	capture-1390508065.jpg	capture.jpg

thank you very much! problem solved.

In the unlikely case that you want to capture more than one iamge per second, use

date +%s.%N

Also, why the middle man?

Why `capture Capture.jpg` then `cp Capture somefilename`. Why not just `capture somefilename`? Or more specifically

while true; do
   capture /path/to/images/img_$(date +%s).jpg
   sleep 1
done

OP mentions

capture 'vfalign transparent ./Capture.jpg'

No idea what id does, maybe he needs Capture.jpg for something.

I agree that if he wants to use bash all the way, Trilby's suggestion of continuous loop and sleep is perfect.

WorMzy · 2014-01-23 22:15:29

If you save the date output to a variable then the watermark could be added during the loop, or, if the processing delay would be too great, it could be done in bulk after the capture loop is completed.
