How do I find the files those do not have an extension? For e.g. in the following screen, I will like to return the file sconnect and not .xls

-rwxr-xr-x 1 root root 12K Mar  7 19:29 ./Purchase_ORDER.xls
-rwxr-xr-x 1 root root 176 Mar  7 19:29 ./sconnect

try:

# find -type f -not -name '*.*'

good luck!

You just do find . \! -name '*.*'

(add -type f if you need exactly files)
