Q:

Find a file in directory where i know part of the filename and the extension

I know the file im looking for begins with a data for example 20131111 and I know the file ends in .log, but I don't know the full file name,
what is a unix command that would allow me to see all files beginning with or containing this date and ending with .log.

A:

Like this, for example:
find /certain/path -type f -name "20131111*.log"

-type f - just files.
-name "20131111*.log" files whose name starts with 20131111 and ends with log.
