## SCRIPT: 01c_multi-img-files_RENAME_ADDprefix_mv.sh
##
## PURPOSE: Adds a user-specified prefix to the names of
##          the user-selected files.
##
## METHOD:  Uses 'zenity --entry' to prompt for the prefix.
##          Uses 'mv' to do the rename.
##
## NOTE: If you accidentally rename the wrong file(s), you can simply
##       rename it/them back, by removing the prefix.

## Created: 2010may19
## 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: 2012may12 Changed script name in comments above and touched up
##                    the comments. Changed some indenting below.
