check for file existence

Hello

I am having a requirement like if there is no file in the directory then i need a message to pop on after the execution of the script.

My script basically does for File in `ls -t $DIRECTORY | tail -1`;
if there is no file the DIRECTORY then the script is simply exiting with out giving any message but i want a message to pop on the screen with non-zero exit code.

Thanks

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)
