I used to be a regular RegEx user. I used to remember all that stuff.
Left the industry after 30 years, and now have CRS disease.
I just need to use the utility to rename files (all in the same directory. hundreds of unique "filename" values) from filename_1.jpg to filename.jpg
There are other files in the directory filename_x.jpg - just want to rename the ones with _1 - not _11, _12, etc.
Can someone help?
