When fortune
is run with no arguments it prints out a
random epigram. Epigrams are divided into several categories, where each
category is subdivided into those which are potentially offensive and those
which are not. The options are as follows:
-a
- Choose from all lists of maxims, both offensive and not. (See the
-o
option for more information on offensive
fortunes.)
-D
- Enable additional debugging output. Specify this option multiple times for
more verbose output. Only available if compiled with
-DDEBUG
.
-e
- Consider all fortune files to be of equal size (see discussion below on
multiple files).
-f
- Print out the list of files which would be searched, but do not print a
fortune.
-l
- Long dictums only.
-m
pattern
- Print out all fortunes which match the regular expression
pattern. See
regex(3)
for a description of patterns.
-o
- Choose only from potentially offensive aphorisms.
Please, please, please request a potentially offensive
fortune if and only if you believe, deep down in your heart, that you are
willing to be offended. (And that if you are not willing, you will just
quit using -o
rather than give us grief about it,
okay?)
... let us keep in mind the basic governing philosophy
of The Brotherhood, as handsomely summarized in these words:
we believe in healthy, hearty laughter -- at the expense of
the whole human race, if needs be.
Needs be.

-s
- Short apothegms only.
-i
- Ignore case for
-m
patterns.
-w
- Wait before termination for an amount of time calculated from the number
of characters in the message. This is useful if it is executed as part of
the logout procedure to guarantee that the message can be read before the
screen is cleared.
The user may specify alternate sayings. You can specify a specific
file, a directory which contains one or more files, or the special word
all
which says to use all the standard databases.
Any of these may be preceded by a percentage, which is a number
N between 0 and 100 inclusive, followed by a
‘%
’. If it is, there will be an
N percent probability that an adage will be picked
from that file or directory. If the percentages do not sum to 100, and there
are specifications without percentages, the remaining percent will apply to
those files and/or directories, in which case the probability of selecting
from one of them will be based on their relative sizes.
As an example, given two databases funny
and not-funny, with funny
twice as big, saying
fortune funny not-funny
will get you fortunes out of funny
two-thirds of the time. The command
fortune 90% funny 10%
not-funny
will pick out 90% of its fortunes from
funny (the “10%
not-funny
” is unnecessary, since 10% is all that is left). The
-e
option says to consider all files equal; thus
fortune -e funny
not-funny
is equivalent to
fortune 50% funny 50%
not-funny
FORTUNE_PATH
- The search path for the data files. It is a colon-separated list of
directories in which
fortune
looks for data files.
If not set it will default to
/usr/share/games/fortune. If none of the
directories specified exist, it will print a warning and exit.
FORTUNE_SAVESTATE
- If set, fortune will save some state about what fortune it was up to on
disk.
- /usr/share/games/fortune/*
- the fortunes databases (those files ending
“-o” contain the
offensive fortunes)
The fortune
utility exits 0 on success,
and >0 if an error occurs. In particular, if
-l
, -m
, or
-s
is specified, failure to find a matching citation
in the selected files counts as an error.
