Perhaps this may be of use:
Code:
$ cat filenames
no1
no2
$ cat paths
yes0
/path/to/file/yes1
/path/to/file/yes2
/path/to/file/no1
/path/to/file/no2
/path/to/file/no2/yes3
$ awk -F/ 'FNR==NR {fn[$0]; next} !($NF in fn)' filenames paths
yes0
/path/to/file/yes1
/path/to/file/yes2
/path/to/file/no2/yes3

NAME

       mrename - program to rename files

SYNOPSIS

       mrename 'pattern' prefix [option]

DESCRIPTION

       This  manual  page  documents  briefly the mrename command.  This manual page was written for the Debian GNU/Linux distribution because the
       original program does not have a manual page.

       mrename is a tool for easy and automatic renaming of many files.  The 'pattern' is the pattern to search files to rename (quoted  to  avoid
       that  bash  resolve  it),  and prefix is the prefix that will be added to the name of each file. The two alternative options for copying or
       moving files in the new name are explained below.  All parameters are needed, and you have to stay and launch the script in the same direc-
       tory of the files to be renamed. The program should be able to write in this directory.

OPTIONS

       There are only the following three options.

       -c     The option -c will copy each file with the new filename.

       -m     The option -m will move each file in the new filename.

       -h     Display help.

EXAMPLE

       If  you	have  a  directory  with two jpeg images prof.jpg and forp.jpg and you want to add them a prefix like item0, item1 etc..  (that is
       item0prof.jpg, item1forp.jpg etc..) do this:

	  cd /path/to/the/images
	  mrename '*.jpg' item -c

       to copy each matching file into another with the new name

	  mrename '*.jpg' item -m

       to rename each file without keeping a copy with the previous name
