- gecos [-c] [-l] [-1] [-r] [-a] [-n] [-f passwordfile] [-o outfile]
-
- DDDEEESSSCCCRRRIIIPPPTTTIIIOOONNN
- Gecos generates a dictionary consisting of all (readable) words that
- occur in the gecos-field (real-name-field) of the passwordfile given by
- the -f switch (if no -f switch is specified, standard-input is used).
- The dictionary will be written to the file specified by the -o switch (if
- no -o switch is specified, standard-output is used). Words can be
- converted to all-lowercase, all-uppercase, name-alike (first character
- uppercase, rest lowercase). Furthermore, all specified conversions can
- also be generated reversed.
-
- Use of one of the options -c, -l or -1 causes the normal word not te be
- generated anymore unless the -n switch is specified.
-
- By default, only ``real words'' (i.e. words of more than two characters,
- consisting only of ['a'..'z', 'A'..'Z']) are generated. Use of the -a
- switch causes all words of more than two characters to be generated.
-
- OOOPPPTTTIIIOOONNNSSS

-
- -l Words will be converted to all-lowercase characters
-
- -1 Same as -l, only first character will be converted to uppercase
-
- -r All specified conversions will also be generated reversed
-
- -a all alphanumeric words of more than two characters are generated.
-
- -n Use of one of the options -c, -l or -1 causes the normal word not
- to be generated. This switch causes the normal word to be generated
- again.
-
- -fname
- Causes passwordfile name to be used instead of standard-input.
-
- -oname
- Causes file name to be used to write dictionary to, instead of
