Recital 9.6 enhanced Recital by enabling it to be used in bash shell scripts and in shell commands which use pipes and/or redirect stdin and stdout.

Note that when used in this manner, no UI commands can be executed and no user interaction is allowed.
- recital < mrprog.prg
- recital < myprog.prg > myoutput.txt
- recital > myoutput.txt <<END
use customers list structure END
- echo "select * from sales!customers where overdue" | recital | wc -l
Individual commands can be executed in shell scripts.
- recital -c "create database sales"
- recital -c "create table sales!invoices (id int, name char(25), due date)"
Expressions can be evaluated and used in shell scripts.
