Hi,

if $var ist your variable, ${#var} will give you the length
of the content of ${var}. So to stop your script try a
test like the one below:

Code:
if [[ ${#var2} -gt 9 ]] 
then  
    echo "too big" 
    exit 1
else 
    echo "just fine"
fi

XtVaGetSubvalues()														XtVaGetSubvalues()

Name
  XtVaGetSubvalues - retrieve the current values of subpart resources, using varargs argument style.

Synopsis
  void XtVaGetSubvalues(base, resources, num_resources, ..., NULL)
	   XtPointer base;
	   XtResourceList resources;
	   Cardinal num_resources;

Inputs
  base	    Specifies the base address of the subpart data structure for which the resources should be retrieved.

  resources Specifies the subpart resource list.

  num_resources
	    Specifies the number of resources in the resource list.

  ..., NULL A  NULL-terminated	variable-length  list  of  resource  names and the addresses at which the values of those resources are to be
	    stored.

Availability
  Release 4 and later.

Description
  XtVaGetSubvalues() obtains the values of the resources named in the variable-length argument list  (and  described  in  the  resource  list
  resources)  from  the subpart structure pointed to by base, and stores those values at the addresses specified in the variable length argu-
  ment list.  Note that the special symbol XtVaTypedArg is not supported by XtVaGetSubvalues().  If XtVaTypedArg is specified in the list,  a
  warning message is issued and the entry is then ignored.

  XtVaGetSubvalues()  is  identical  to XtGetSubvalues() except that the args array of resource names and values and the num_args argument of
  that function are replaced with a NULL-terminated variable-length argument list.

  See XtGetSubvalues() for more information on this function.  See XtVaSetValues() for more information  on  using  variable-length  argument
  lists to specify resources.  See XtGetApplicationResources() for information on how to declare an XtResourceList.
