There is about 300 directories I'm walking through here.
I know you got another reply using other utilities, but since you asked
for a regex command, I though this might be interesting. The sort -u is
just there to take out any repeated numbers and then sort them
alphanumerically.
ls | perl -n -e 'print "$1\n" if ( /([0-9.]+).*/ );' | sort -u
If you want to include the dashes and underscores in the listing, just
change the regex to:
/([0-9.]+[-_]?).*/
