## SCRIPT: 00_multiFiles_shoFILETYPEs_file.sh
##
## PURPOSE: For a set of user-selected files, this script shows their
##          file types, using the 'file' command in a for-loop.
##
## METHOD:  In a for-loop, for each of the user-selected files,
##          concatenates the output of the 'file' command, onto a text file.
##
##          Shows the text file in a text-file viewer of the user's
##          choice.
##
## HOW TO USE: In Nautilus, go to any directory, select one
##             or more files, right-click, choose this
##             script to run (in an FE NautilusScripts submenu).
##             (See script name above.)

## Created: 2011may10
## Changed: 2011may11 Get 'nautilus-scripts' directory via an include script.
## Changed: 2011jul07 Changed to handle filenames with embedded spaces.
##                    (Removed use of FILENAMES var and use a 'for' loop
##                     WITHOUT the 'in' phrase.  Ref: man bash )
## Changed: 2012feb29 Changed the script name in the comment above.

## FOR TESTING: (show statements as they execute)
