See my comment on the question for context.

From a shell:

echo file-myfle_20130207_094852am.csv | tr -cd /0-9/
20130207094852

With Perl:

echo file-myfle_20130207_094852am.csv | perl -pe 's/\D//g'
20130207094852

Like this (this is pretty common among Regex tutorials)

\d+

Each group will be the numbers.
