Full Discussion: mailx in kornshell script passing return code to CA-Unicenter

Tools mailx in kornshell script passing return code to CA-Unicenter
I have a KornShell script that has successfully been scheduled through Cron. We are in the process of changing over from Cron to using CA-Unicenter. To negative test the script I put a bad return code in. At the bottom of the script an e-mail is sent using mailx and then the return code is set using "exit 2". However, CA-Unicenter gets a zero return code back. If I comment out the mailx code, then CA-Unicenter will show up with a return code of 2. My assumption is that the mailx command ends with a zero return code and CA-Unicenter gets it and assumes its from the KornShell script. Here's the piece of code in question:

CENTMSGRC=2
print $CENTMSGRC >> /appl/cmddba/bin/job.log

mailx -s "$subject" "$MAILTO" </appl/cmddba/bin/job.log

print $CENTMSGRC >> /appl/cmddba/bin/job.log

exit $CENTMSGRC

Do you have any idea if my theory is correct? And if it is, do you know a solution to my problem besides creating another Script that will just send the e-mail message and have the script executed after the first one.

Thanks,
Connie

tcl_allowexceptions

Tcl_AllowExceptions(3)					      Tcl Library Procedures					    Tcl_AllowExceptions(3)

__________________________________________________________________________________________________________________________________________________

NAME

       Tcl_AllowExceptions - allow all exceptions in next script evaluation

SYNOPSIS

       #include <tcl.h>

       Tcl_AllowExceptions(interp)

ARGUMENTS

       Tcl_Interp *interp (in)		Interpreter in which script will be evaluated.
_________________________________________________________________

DESCRIPTION

       If  a  script is evaluated at top-level (i.e. no other scripts are pending evaluation when the script is invoked), and if the script termi-
       nates with a completion code other than TCL_OK, TCL_ERROR or TCL_RETURN, then Tcl normally converts this into a TCL_ERROR  return  with	an
       appropriate  message.  The particular script evaluation procedures of Tcl that act in the manner are Tcl_EvalObjEx, Tcl_EvalObjv, Tcl_Eval,
       Tcl_EvalEx, Tcl_GlobalEval, Tcl_GlobalEvalObj, Tcl_VarEval and Tcl_VarEvalVA.

       However, if Tcl_AllowExceptions is invoked immediately before calling one of those a procedures, then arbitrary completion codes  are  per-
       mitted from the script, and they are returned without modification.  This is useful in cases where the caller can deal with exceptions such
       as TCL_BREAK or TCL_CONTINUE in a meaningful way.

KEYWORDS

       continue, break, exception, interpreter
