filesnames that contain only numbers

[sbergami]

hi to everyone,
I would need to configure a rule in filename.rules.conf that blocks the excel file if the name is composed only by numbers, for example 12345.xls.

I tried to enter

deny [0-9] \. xls $ - -
deny [0-9] \. .xlsx $ - -

but this block all excel files that contain at least one number.
What would be the correct syntax?
Thank you

Try this

Code: Select all

^[0-9]+\.xlsx$
