Is there a wildcard for a single digit (and single character)? When I download images from the Internet with Firefox with names like "203344251_355840562566401_5108092898173595155_n." I would like to find these, and I figure just screening for file names that start with nine digits will do it. I confess this is an intellectual exercise because they aren't hard to find with my eyeballs, it just feels like Find file should do it.
Yes I imagine Regex can do this, but learning how is a pain, and every time I do learn, I won't remember how I did it the next time I need it.

for that you are best off with a regular expression [0-9] and a repeat count. Sorry I am no regexp guru but it is definitely doable

If I go to regex101: build, test, and debug regex, and test the following regex syntax:

Code: Select all

^\d{9}_

I get results:


If I try the same regex syntax in xplorer², I get no results.
It would be helpful to have a complete description of the regex syntax available in xplorer².

I wish that not every single tool on this planet came with its own regex syntax.

Maybe ^\\d{9} works? (I*m not on an x²-enabled PC right now, surprisingly.)

[nikos]

I just tried it and ^\d{8}_ seems to work!?
make sure you enable regular expressions in x2 setting the fuzzy box to 0 (next to NAMED box)

My bad! Sorry! I forgot to set the fuzzy box to 0!
^\d{9}_ does work!
