    can use look-ahead:

     % grep -P '(?=.*foo)(?=.*bar)' FILES

    but this does not capture (thus highlight) the patterns. To do that, you
    can pipe to grep once more:

     % grep -P '(?=.*foo)(?=.*bar)' FILES | grep -P '(foo|bar)'

    but you introduce the complications of double filtering (e.g. filenames
    in FILES is now the subject of the second grep).

    Note that searching for multiple patterns in particular order
    ('foo.*bar'), or searching for aternates from multiple patterns
    ('foo|bar') is no problem in grep.

    Some tools have been written to make it easier to specify multiple
    patterns:

    abgrep (from App::abgrep) sports a "--all" option to require all
    patterns to appear in a line (in no particular order). Normally, when

    cpangrep (from App::cpangrep) is a CLI for web service
    <https://cpan.grep.me>, which is no longer operating. To grep from files
    on CPAN, use <https://metacpan.org>.

    grepl (from App::Grepl) uses PPI to let you grep over Perl *documents*;
    it allows you to do things like: search only in Perl code comments or
    inside string literals.

    podgrep (from pmtools) greps from POD sections of Perl source.

    csv-grep (from App::CSVUtils) allows you to apply Perl code against rows
