Unix Tip #4582- September 27, 2025
SHELL SCRIPTING A SQLPLUS SCRIPT
Here is a tip on how to run sqlplus scripts within a shell script.
It is an example of how to pass database values into shell variables
and to make shell scripts more dynamic. This maybe elementary to some
folks but hope it helps others.....Here is the syntax:
#!/bin/sh
dummyvar=`sqlplus -s username/password <
set pagesize 0 feedback off ver off heading off echo off
select sysdate from dual;
exit;
end`
echo "system date is " $dummyvar
#end of shell script
This will retrieve the system date from Oracle but you get the idea
that you can expand the select script to get whatever you want from
the database and place it in a shell variable where you can make
decisions on it.
