Many thanks. I am sorry, I should have specified that I work in a Windows environment.
Playing round with the AWK regex, I found that it worked beautifully as a Unix regex. My text-editor allows me to choose Unix/Perl as Regexes. All I had to was strip off the forward slashes and I could identify all the singletons.

mkpwdict
mkpwdict(1M) System Administration Commands mkpwdict(1M)
NAME
mkpwdict - maintain password-strength checking database
SYNOPSIS
/usr/sbin/mkpwdict [-s dict1,... ,dictN] [-d destination-path]
DESCRIPTION
The mkpwdict command adds words to the dictionary-lookup database used by pam_authtok_check(5) and passwd(1).
Files containing words to be added to the database can be specified on the command-line using the -s flag. These source files should have a
single word per line, much like /usr/share/lib/dict/words.
If -s is omitted, mkpwdict will use the value of DICTIONLIST specified in /etc/default/passwd (see passwd(1)).
The database is created in the directory specified by the -d option. If this option is omitted, mkpwdict uses the value of DICTIONDBDIR
specified in /etc/default/passwd (see passwd(1)). The default location is /var/passwd.
OPTIONS
The following options are supported:
-s
Specifies a comma-separated list of files containing words to be added to the dictionary-lookup database.
-d
Specifies the target location of the dictionary-database.
FILES
/etc/default/passwd
See passwd(1).
/var/passwd
default destination directory
