Hi Todd, 

Not that I am aware. The naive way is just to pipe them:

~$ echo 'roses are red' | raku -pe 's/roses/lilacs/' | raku -pe 's/red/blue/'
lilacs are blue 


The Raku way would be combining those two statements into one Raku call:

~$ echo 'roses are red' | raku -pe 's/roses/lilacs/; s/red/blue/'
lilacs are blue

#OR ("big-S" notation below)

~$ echo 'roses are red' | raku -ne 'S/roses/lilacs/ andthen S/red/blue/.put'
lilacs are blue


The `andthen` call reloads the `$_` topic variable. For more examples, see:
