Question While loop subshell problem
Hi,

I have the below script

Code:
while true; do
       read -p "Please enter schema password: " -s -e pswd1
       echo
       read -p "Please retype schema password: " -s -e pswd2
       echo
       [ "X$pswd1" != "X$pswd2" ] && { echo -e "password mismatch.\n"; continue; }
       validateOraclePassword $pswd1
       [ $? -eq 0 ] && break
done

where "validateOraclePassword" is a function which checks if the password follow our database policy.

The above code is used by multiple components and so i'm trying to build a master script which calls all components in 1 go as below

Code:
/opt/component1.sh <<!
password
password
!
/opt/component2.sh <<!
password1
password1
!

My problem is that WHILE loop creates a subshell when it run and because of that the $pswd1 is empty when validateOraclePassword function is called.


Any idea how i can fix it?

Many thanks in advanced,

Dani

capture-schema

capture-schema(1m)					    Application Server Utility						capture-schema(1m)

NAME

       capture-schema -  stores the database metadata (schema) in a file for use in mapping and execution

SYNOPSIS

       capture-schema-dburl url-username name- password password-driver a_jdbc_driver [-schemaname name] [-table tablename]* [-out filename]

       Stores  the  database metadata (schema) in a file. You can also use the Sun Java System Studio IDE to capture the database schema. Run cap-
       ture-schema as the same database user that owns the tables, so that the -username and -schemaname options  are  given  the  same  username.
       Additionally, you can grant the database user running the capture-schema command the ANALYZE ANY TABLE privilege.

OPTIONS

       -dburl		       JDBC URL expected by the driver for accessing a database.

       -username	       user name for authenticating access to a database.

       -password	       password for accessing the selected database.

       -driver		       JDBC driver classname in your CLASSPATH.

       -schemaname	       name of the user schema being captured. If not specified, the default will capture metadata for all tables from all
			       the schemas accessible to this user. Specifying this parameter is highly recommended. If more than  one	schema	is
			       accessible to this user, more than one table with the same name may be captured which will cause problems.

       -table		       name of the table; multiple table names can be specified.

       -out		       output target; defaults to stdout. This parameter corresponds to the schema sub-element of the sun-cmp-mapping ele-
			       ment in the sun-cmp-mapping_1_1.dtd file.

EXAMPLES

       Example 1: Using capture-schema

       capture-schema -dburl jdbc:oracle:thin:@sadbuttrue:1521:ora817
       -schemaname cantiflas -username CANTIFLAS -password enigma -driver
       oracle.jdbc.driver.OracleDriver
