Grep Options

[SoloCDM <deedsmis ris net>]

While using grep, what is the best way to search for two subjects
within the same line instead of the following?

cat <filename> | grep <subject_one> | grep <subject_two>

This is not an "or" search with "-e", but an "and" search.

Note: Detailed Document(s) and Sample(s) are more than welcome.
