Find long filenames using GNU find -regex

Question

Hi

I'm trying to find all long filenames in a directory using:

find . -regex './[^/]\{5,\}.txt' 

According to the GNU find documentation, -regex uses emacs regex by default. So this should give me all files longer than 5 characters (excluding extension). Unfortunately it does not work. It matches nothing. I've tried various variations on this theme but to no avail. Any ideas? Does GNU find simply not support the repetition qualifier?

Thanks

Pascal

Answer 1

Add

-regextype posix-extended

and no need to escape { }

find . -regextype posix-extended -regex './[^/]{5,}.txt' 

Answer 2

why so complicated?

find /path -type f -iname "??????*.txt"
