Setting Variables not working
Hi all,
I am trying to set up some variables in a shell script. The variables contain values of various paths needed to run a java module. The problem is the variables dont seem to be setting at all.
here is what i am trying to do :
JAR_HOME=/home/was5/bdcms/scheduledjobs/lib
export JAR_HOME
JAVA_HOME=/usr/java131/bin
export JAVA_HOME
SOURCE_HOME=/home/was5/bdcms/scheduledjobs/src
export SOURCE_HOME
CLASS_PATH=.:/home/was5/bdcms/scheduledjobs/src/classes12.jar
export CLASS_PATH
echo $CLASS_PATH
------------END of code -------------
This echo prints the value correctly. Where as if i do the same from unix prompt after executing the script, the variable is always empty. I have tried all kinds of things here(including export CLASS_PATH=value and export SET CLASS_PATH=value among others) and am not able to figure the problem.
Any help or pointers are appreciated.
Thanks

Hi all,
This is my first post here. I need to set up a few environment variables with a shell script. Some are hard-coded, but some should come from other commands or as input from the user. How do I do that?
For example, I need to export a variable as such:

EXPORT(P) POSIX Programmer's Manual EXPORT(P)
NAME
export - set the export attribute for variables
SYNOPSIS
export name[=word]...
export -p
DESCRIPTION
The shell shall give the export attribute to the variables corresponding to the specified names, which shall cause them to be in the envi-
ronment of subsequently executed commands. If the name of a variable is followed by = word, then the value of that variable shall be set to
word.
The export special built-in shall support the Base Definitions volume of IEEE Std 1003.1-2001, Section 12.2, Utility Syntax Guidelines.
When -p is specified, export shall write to the standard output the names and values of all exported variables, in the following format:
"export %s=%s
", <name>, <value>
if name is set, and:
"export %s
", <name>
if name is unset.
The shell shall format the output, including the proper use of quoting, so that it is suitable for reinput to the shell as commands that
achieve the same exporting results, except:
1. Read-only variables with values cannot be reset.
2. Variables that were unset at the time they were output need not be reset to the unset state if a value is assigned to the variable
between the time the state was saved and the time at which the saved output is reinput to the shell.
When no arguments are given, the results are unspecified.
OPTIONS
See the DESCRIPTION.
OPERANDS
See the DESCRIPTION.
STDIN
Not used.
INPUT FILES
None.
ENVIRONMENT VARIABLES
None.
ASYNCHRONOUS EVENTS
Default.
STDOUT
See the DESCRIPTION.
STDERR
The standard error shall be used only for diagnostic messages.
OUTPUT FILES
None.
EXTENDED DESCRIPTION
None.
EXIT STATUS
Zero.
CONSEQUENCES OF ERRORS
Default.
The following sections are informative.
APPLICATION USAGE
None.
EXAMPLES
Export PWD and HOME variables:
export PWD HOME
Set and export the PATH variable:
export PATH=/local/bin:$PATH
Save and restore all exported variables:
export -p > temp-fileunset a lot of variables... processing. temp-file
RATIONALE
Some historical shells use the no-argument case as the functional equivalent of what is required here with -p. This feature was left
unspecified because it is not historical practice in all shells, and some scripts may rely on the now-unspecified results on their imple-
mentations. Attempts to specify the -p output as the default case were unsuccessful in achieving consensus. The -p option was added to
allow portable access to the values that can be saved and then later restored using; for example, a dot script.
FUTURE DIRECTIONS
None.
