How to print warning messages on console when we use exec command?
I am having script in which for logging I am using exec command. I am calling another script/program through this script which is designed for another user id.
So, After running script it is giving warning message as "This program has been designed for another user id. Please press Enter to continue."
After went through log I understood to finish execution we need to hit enter one more time. But everytime this is not possible.
I want to print this warning message on console so whoever is running script can read the warning message.
Help is much appreciated.
Thanks,
Vikram.

How can I use the exec command to log my korn shell session to the screen and the log file?
Currently I have this command:
$exec 1> ${LOG} 2>&1
This logs the output to the log file only. I want it to go to the screen also. Is this possible with this command?

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 Tcl 7.4 Tcl_AllowExceptions(3)
