## SCRIPT: 00_multiFiles_RENAME_ADDsuffix_mv.sh
##
## PURPOSE: Adds a user-specified suffix to the names of
##          the user-selected files.
##
## METHOD:  Uses 'zenity' to prompt for the suffix.
##          Uses the 'mv' command, in a loop, for the renames.
##
## HOW TO USE: In Nautilus, select one or more files in a directory.
##             (The selected files can be directories.)
##             Right click and, from the 'Scripts >' submenus,
##             choose to run this script (name above).
##
## UNDO NOTE: 
##       If you accidentally rename the file(s) wrongly, you can usually
##       rename it/them back, by removing (or changing) the suffix ---
##       using another feNautilusScript 'CHANGEfiles' tool.
##
## Created: 2010aug22
## Changed: 2011jul07 Changed to handle filenames with embedded spaces.
##                    (Removed use of FILENAMES var and we use a 'for' loop
##                     WITHOUT the 'in' phrase.  Ref: man bash )
## Changed: 2012feb13 Changed script name. Added the 'HOW TO USE' section
##                    above. Added to the 'METHOD' section above.
##                    Changed the indenting below.

## FOR TESTING: (show statements as they execute)
# set -x
