Looking at the jq github repo led me to also find ag, an ack-grep replacement. Both are in my distro's repositories.

--output=expr
Output the evaluation of expr for each line (turns off text
highlighting) If PATTERN matches more than once then a line is
output for each non-overlapping match. For more information please
see the section "Examples of --output".
cat file | ag '(\w+) (\d+)' --output '$1 is $2 years old'
sed -rn 's/([a-zA-Z]+) ([0-9]+)/\1 is \2 years old/p' file cat file | perl -ne 'print if s/(\w+) (\d+)/\1 is \2 years old/'

But when I saw mVChr's sed line, and then again the perl line, I was reminded "Oh, right, old school." And I wondered for the Nth time how much of old school has been unknowingly reinvented, and how many times.
Nevertheless, I like the new(er) tools in this thread too.
