How to execute external scripts that returns error code

Question

Hi,
What is the best approach to execute a unix shell scripts in ODI thats return a code e.g. 1- found , 2 - not found. The return code needs to assigned to a ODI variable. I have gone through some posts that explained how to refresh odi variable from file. well in that case i have to write the error code to a file and then read to a ODI variable. Is there any direct approach available ? Is there any other way I can assign values to ODI variable other than its refresh methods ( select from <source>) for e.g. Inside odi procedure ?
Thanks you all for answering this

In order to reduce the steps we need to do that using java itself. It will be something like this .
Step 1. ODI procedure - Technology Java Bean shell .
<@
JAVA OS COMMOND CODE TO TRIGGER THE PEARL SCRIPT.
GET THE RETURN INTO JAVA VARIABLE ( SAY FOR EX result )
@>
Step 2. Creating the variable.
select any oracle schema
select '<@=result@>' from dual
and call this variable in refresh mode in package.
Step 3. processing with variable what ever you wish to do .
Personally i have not tried the java os command to get the return code . I will look into this and let you know sooner or later. If you want you can explore the code or google the code and see if what you are planning to achive is possible ,else the other way can be using the file as you know.
