Making image files into an ordered number sequence.
Say you have a bunch of files in a directory that need sensible filenames so that they can be fed into another program easily.
ie you want this.
0001.jpg
0002.jpg
0003.jpg
0004.jpg
from say this:
IMG_9998.JPG
IMG_9999.JPG
IMG_0001.JPG
IMG_0002.JPG
eg you camera has rolled over from IMG_9999.JPG to IMG_0001.JPG
(actually this is a bad example).
we need to tell find or ls below to order the files by creation date in this case.
just say you files looked like this.
IMG_3454.JPG
IMG_3455.JPG
IMG_3456.JPG
IMG_3457.JPG
(install gawk first)
find . -name '*.JPG' | gawk 'BEGIN{ a=1 }{ printf "mv \"%s\" %04d.jpg\n", $0, a++ }' | bash
Careful.. find will work recursively ls may work better...
ls *.JPG | gawk 'BEGIN{ a=1 }{ printf "mv \"%s\" %04d.jpg\n", $0, a++ }' | bash
work in progress....
