I have read other posts on this topic, but none were exactly what I need to know. I have a series of bmp image files that have names like: wl6_pic_0115.bmp
These files are all in sequential order, and there are no missing numbers in the filenames. All of them are 4-digit numbers beginning with 0. I need to renumber them beginning at 0018 and ending at 0145, incrementing each one by 1, so 18 -> 19 through 145 -> 146. How can I do this with a regular expression?
