In terminal how do I rename files to sequential numbers whilst keeping the original order?
I want to rename an image sequence with even numbers. The image sequence is already named in order 1.tif, 2.tif, 3.tif, 4.tif, etc but I want them to be named 2.tif, 4.tif, 6.tif, 8.tif etc. (I need them to stay in that order because they are animation frames)
