What regexp to use?

Question

Regular Expressions

I don’t rummage in regexps, but the situation is this: when adding an element to an attachment, Joomla assigns a stamp to the file name. this stamp should be removed. example: the original filename is ppl.jpg. when adding, an underscore and ten digits are assigned - ppl_1448462046.jpg
What regexp can be used to cut _1448462046? (numbers may vary)

Answer 1

Hello, try this one .
#(_\d{10,})#gim

Answer 2

With .jpg extension:
Without .jpg extension:
_\d+$
