Top Forums Shell Programming and Scripting BASH - Propagation of error codes Post 302935825 by jcdole on Thursday 19th of February 2015 10:59:10 AM

My real program is working correctly.
These script are just shown to explain the question.
The code by itself is not important.

My real problem is the coding line
Code:
 VERSION_VALUE=$( function2 "$MY_TEMPFILE" "a_string" "another_string" | not_important_function_b )
RETURN_CODE=$?

If the last part of a pipe return no error and if a previous part of a pipe return one error (say 123)
1°) What is the value of $RETURN_CODE 0 or 123
2°) Is the return code set to 0 ( if not, I have a problem somewhere in my code)
how to get the error code (123) for the global result which must be considered as failing.

Thank you for helping
