RedHat Calling a script from master script to get value from called script
I am trying to call a script(callingscript.sh) from a master script(masterscript.sh) to get string type value from calling script to master script. I have used scripts mentioned below.
Code:
#masterscript.sh
 
./callingscript.sh
echo $fileExist
 
#callingscript.sh
 
echo "The script is called"
fileExist="XYZ"
export $fileExist

When I run the masterscript.sh in the output one blank line is coming but I want to print "XYZ"

Please help ASAP.

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)
