File exists and is empty
I've got a script with this snippet:

if [ -s $DATA_DIR/file.dat ]
then

I know that the -s indicates that the file exists and is not empty. How can I specify that the file exists, but is empty? I thought I could do:

if [[ -a $DATA_DIR/file.dat && ! -s $DATA_DIR/file.dat ]]
then

But this generates a "else unmatched" error on the else that follows.

xtaugmenttranslations

XtParseTranslationTable(3)					   XT FUNCTIONS 					XtParseTranslationTable(3)

NAME

       XtParseTranslationTable, XtAugmentTranslations, XtOverrideTranslations, XtUninstallTranslations - manage translation tables

SYNTAX

       XtTranslations XtParseTranslationTable(String table);

       void XtAugmentTranslations(Widget w, XtTranslations translations);

       void XtOverrideTranslations(Widget w, XtTranslations translations);

       void XtUninstallTranslations(Widget w);

ARGUMENTS

       table	 Specifies the translation table to compile.

       translations
		 Specifies the compiled translation table to merge in (must not be NULL).

       w	 Specifies the widget into which the new translations are to be merged or removed.

DESCRIPTION

       The XtParseTranslationTable function compiles the translation table into the opaque internal representation of type XtTranslations.  Note
       that if an empty translation table is required for any purpose, one can be obtained by calling XtParseTranslationTable and passing an empty
       string.

       The XtAugmentTranslations function nondestructively merges the new translations into the existing widget translations.  If the new transla-
       tions contain an event or event sequence that already exists in the widget's translations, the new translation is ignored.

       The XtOverrideTranslations function destructively merges the new translations into the existing widget translations.  If the new transla-
       tions contain an event or event sequence that already exists in the widget's translations, the new translation is merged in and override
       the widget's translation.

       To replace a widget's translations completely, use XtSetValues on the XtNtranslations resource and specify a compiled translation table as
       the value.

       The XtUninstallTranslations function causes the entire translation table for widget to be removed.
