add_suffix.sh

#In Bash and zsh you can do this with Brace Expansion. This simply expands a list of items in braces. For example:

# echo {vanilla,chocolate,strawberry}-ice-cream
#vanilla-ice-cream chocolate-ice-cream strawberry-ice-cream
#So you can do your rename as follows:

mv {,new.}original.filename
#as this expands to:

#mv original.filename new.original.filename
