a bit like this, but i'm not sure what to add to make it work
$ (echo a ; echo b ; echo c) | perl -e 'a'

Performing a regex search-and-replace is just as easy: $string =~ s/regex/replacement/g; I added a “g” after the last forward slash. The “g” stands for “global”, which tells Perl to replace all matches, and not just the first one.
Regular Expression (Regex or Regexp or RE) in Perl is a special text string for describing a search pattern within a given text. Regex in Perl is linked to the host language and is not the same as in PHP, Python, etc. Sometimes it is termed as “Perl 5 Compatible Regular Expressions“.
(echo a; echo b; echo c) | perl -ne 'print if /a/'
