Problem with print command
Hi,
I have a small script and am having problem at one point. The script runs another script called Run_SQL.sh. All I am trying to do is if the return code from the script is not zero(0) then display some message(which is working fine) and if the return code is zero then run the SED command and run the print command below it.(see in RED BOLD below). My SED command executes fine but the print command sometime works and sometime does not work. Its sporadic. I know there is something very simple but am not able to figure out.

Any advice will be appreciated.

SQLDIR=$t_path
SQLLISTFILE=${t_path}/$SQLFILE

for SQLNAME in `cat $SQLLISTFILE`
do
SQLFILENAME=${SQLDIR}/${SQLNAME}
print "Running ${SQLNAME}"

Run_SQL.sh -f $SQLNAME
if [ $? -ne 0 ]
then
print "There is error in ${SQLNAME}. Check the file."
exit -1
else
var=`head -1 ${SQLLISTFILE}`
if [ "$var" == "$SQLNAME" ] then
sed '1d' ${SQLLISTFILE} | tee ${SQLLISTFILE} > /dev/null 2>&1 --->This command executes fine
print "${SQLNAME} ran sucessfully" --->This is where I am having problems. This command sometime displays and sometime does not displays text.
fi

fi

The command in bold above run sucessfully and sometime it does not show up at all even if the sed command is sucessful. I have to run this print command after the sed command only.

I will really appreciate any advice in this regard.

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
