Operating Systems SCO Logout automatically when exiting a script Post 302936253 by rbatte1 on Tuesday 24th of February 2015 07:25:10 AM

The command exit does just that, exit the current process. If the current process is the login shell, then you get logged off. What you are doing by calling exec program is to say 'replace the current shell with program' so when the program ends, there is nothing to go back to.

What is your desired response?
  • CNTL-d ends program but does not log out (where do you go then)
  • Failure to find program logs out
  • Normal termination logs out
  • The complete opposite of any/all of these?
If you can be clear about what you want to happen, then we can probably work out a way to make it so.

__________________________________________________________________________________________________________________________________________________

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)
