My Samsung Galaxy S doesn't like files where the name contains a long string after the first dot. I guess some part of the software has a too short buffer for the file extension. How can I find all files on my Micro-SD-Card mounted at /media/sd where the filename has more than five characters after the first dot?
Reading the find manpage, I thought
find . -regex '.*\..\{5,\}'
would work, but it doesn't give any hits, so I somehow don't get my regular expression right.
