Question

I’m using the following regex find command in OS X terminal to find a whole load of files that have 8 digit file names followed by either a .jpg, .gif, .png or .eps extension. The following produces no results even though I’ve told OS X/BSD find to use modern regex

find -E ./ -iregex '\d{8}'

Using http://rubular.com/ (http://rubular.com/r/YMz3J8Qlgh) shows that the regex pattern produces the expected results and OS X produces the results when typing

find . -iname '[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9].*'

But this seems a little long winded.

Answer 1

These commands works on OSX

find -E . -iregex '.*/[0-9]{8}\.(jpg|png|eps|gif)'

this command matches 12345678.jpg , not 123456789.jpg

find -E . -iregex '.*/[0-9]{8,}\.(jpg|png|eps|gif)'

this command matches 12345678.jpg and 123456789.jpg
