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

SYSTEMD-PATH(1)                                                    systemd-path                                                    SYSTEMD-PATH(1)

NAME

       systemd-path - List and query system and user paths

SYNOPSIS

       systemd-path [OPTIONS...] [NAME...]

DESCRIPTION

       systemd-path may be used to query system and user paths. The tool makes many of the paths described in file-hierarchy(7) available for
       querying.

       When invoked without arguments, a list of known paths and their current values is shown. When at least one argument is passed, the path
       with this name is queried and its value shown. The variables whose name begins with "search-" do not refer to individual paths, but instead
       to a list of colon-separated search paths, in their order of precedence.

OPTIONS

       The following options are understood:

       --suffix=
           The printed paths are suffixed by the specified string.

       -h, --help
           Print a short help text and exit.

       --version
           Print a short version string and exit.

EXIT STATUS

       On success, 0 is returned, a non-zero failure code otherwise.
