How to rename and clean up filenames using regex on linux, ubuntu, etc (there are a lot of files)

Answer 1

Take and clean.
Without concrete examples, it is not known what to say.
Well, the rename utility can do regexp

Answer 2

The find command supports regexp (and more)
For example

$ find . -regextype sed -regex ".*/[a-f0-9\-]\{36\}\.jpg"
./test/81397018-b84a-11e0-9d2a-001b77dc0bed.jpg
./81397018-b84a-11e0-9d2a-001b77dc0bed.jpg

Well, if you find anything

find . -regextype sed -regex ".*/[a-f0-9\-]\{36\}\.jpg" --exec rm {} \;
