Such as by file extension?
For instance, I don't want to see .DS_STORE files, but I want to see all .htaccess files. Is there a way to do this?
Open a terminal and type
ls -a | grep -G .YOUR_EXTENSION$
See http://www.robelle.com/smugbook/regexpr.html for more information of regex
Also man grep
and man ls
will be of use
