Failed to export parameters from configuration file
Hi folks,

I have the following configuration file:
Code:
/tmp> cat nir.conf 
SCHEMA_NAME=NIR
SCHEMA_PASS=NIR
CGI_PORT=:7778
HOST_PORT=:7778 
COMPATIBLE=10.1.0
STATIC_FILES_INITIAL=core 
TIME_ZONE=-2
DAYLIGHT_SAVING_TIME=NULL
CP_PLUGIN_SUPPORTED=FALSE
CPPlugin=DefaultCPPlugin
REPLACE_BO_USER=NO

From this file I should generate "define" parameters file for sqlplus and exporting those parameters in ksh environment.
I wrothe the following script:
Code:
#! /bin/ksh

RESPONSE_FILE=/tmp/nir.conf
cat $RESPONSE_FILE | while read line
do
 echo "define $line" >> /tmp/def_var_DatabaseLayer.sql
 export $line
done
echo ${SCHEMA_NAME}

The problem is that the parameters are not exported:

Code:
/tmp> ./gen_param_files.ksh 

RESPONSE_FILE=/tmp/nir.conf
+ RESPONSE_FILE=/tmp/nir.conf
cat $RESPONSE_FILE | while read line
do
 echo "define $line" >> /tmp/def_var_DatabaseLayer.sql
 export $line
done
+ cat /tmp/nir.conf
+ read line
+ echo define SCHEMA_NAME=NIR
+ >> /tmp/def_var_DatabaseLayer.sql 
+ export SCHEMA_NAME=NIR
+ read line
+ echo define SCHEMA_PASS=NIR
+ >> /tmp/def_var_DatabaseLayer.sql 
+ export SCHEMA_PASS=NIR
+ read line
+ echo define CGI_PORT=:7778
+ >> /tmp/def_var_DatabaseLayer.sql 
+ export CGI_PORT=:7778
+ read line
+ echo define HOST_PORT=:7778
+ >> /tmp/def_var_DatabaseLayer.sql 
+ export HOST_PORT=:7778
+ read line
+ echo define COMPATIBLE=10.1.0
+ >> /tmp/def_var_DatabaseLayer.sql 
+ export COMPATIBLE=10.1.0
+ read line
+ echo define STATIC_FILES_INITIAL=core
+ >> /tmp/def_var_DatabaseLayer.sql 
+ export STATIC_FILES_INITIAL=core
+ read line
+ echo define TIME_ZONE=-2
+ >> /tmp/def_var_DatabaseLayer.sql 
+ export TIME_ZONE=-2
+ read line
+ echo define DAYLIGHT_SAVING_TIME=NULL
+ >> /tmp/def_var_DatabaseLayer.sql 
+ export DAYLIGHT_SAVING_TIME=NULL
+ read line
+ echo define CP_PLUGIN_SUPPORTED=FALSE
+ >> /tmp/def_var_DatabaseLayer.sql 
+ export CP_PLUGIN_SUPPORTED=FALSE
+ read line
+ echo define CPPlugin=DefaultCPPlugin
+ >> /tmp/def_var_DatabaseLayer.sql 
+ export CPPlugin=DefaultCPPlugin
+ read line
+ echo define REPLACE_BO_USER=NO
+ >> /tmp/def_var_DatabaseLayer.sql 
+ export REPLACE_BO_USER=NO
+ read line
echo ${SCHEMA_NAME}
+ echo

As you can see,${SCHEMA_NAME} is empty.
What did I do wrong?
Is there a better way to export parameters in loop according to configuration file?

Thanks in advance,
Nir

not tested.....
Code:
#! /bin/ksh

RESPONSE_FILE=/tmp/nir.conf
. "${RESPONSE_FILE}"
sed 's/^/define /g' "${RESPONSE_FILE}" > /tmp/def_var_DatabaseLayer.sql
echo ${SCHEMA_NAME}

Couple of problems there. Setting a variable is not the same as exporting a variable. Also he wanted to append.

RESPONSE_FILE=/tmp/nir.conf
export $(< $RESPONSE_FILE)
sed 's/^/define /' < $RESPONSE_FILE=/tmp/nir.conf >>/tmp/def_var_DatabaseLayer.sql
