That's where ripgrep's -r/--replace flag comes in handy: $ echo 'foobar start: 123 end quuxbar' | rg 'start: ([0-9]+) end'
foobar start: 123 end quuxbar
$ echo 'foobar start: 123 end quuxbar' | rg 'start: ([0-9]+) end' -r '$1'
foobar 123 quuxbar
$ echo 'foobar start: 123 end quuxbar' | rg 'start: ([0-9]+) end' -or '$1'
123
