Recital 10 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. If stdin is not redirected then recital will startup and operate as normal in a terminal window. Additionally you can use heredoc to denote a block of recital commands that should be executed. 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.
# VER=`recital -e "version(1)"`
