+
+ 1. Introduction
+
+ When a user logs into a system normally the /etc/motd is displayed. (
+ You can disable this by creating the file ~/.hushlogin.) You will be
+ greeted by something like ''welcome to 127.0.0.1''. That is boring.
+
+ Here comes ''fortune'' to the rescue. The package comes with 3
+ programs: fortune,strfile and unstr.
+
+
+ 2. Usage of fortune, strfile and unstr
+
+ The programs have clear distinguished jobs: presentation, assembly and
+ disassembly of the fortune databases.
+
+
+ 2.1. Fortune
+
+ fortune is the presenter program. A simple application is to call the
+ program in the crontab and modify the /etc/motd. e.g.:
+
+ ______________________________________________________________________
+ */10 * * * * /usr/bin/fortune >/etc/motd
+
+ To select a given database with quotes simply add the database as argument.
+
+ */10 * * * * /usr/bin/fortune myquotes >/etc/motd
+ ______________________________________________________________________
+
+
+ You can also specify more than one database file. Then fortune will
+ consider both files equally often.
+
+ ______________________________________________________________________
+
+ > fortune myquotes startrek
+ ______________________________________________________________________
+
+
+ Some people like some quotes more than others. So your can manipulate
+ the equilibrium by adding probabilities.
+
+
+
+ ______________________________________________________________________
+
+ > fortune 90% myquotes 10% startrek
+ ______________________________________________________________________
+
+
+ fortune has some additional command line switches but its beyond the
+ scope of this document to explain them. check the man page instead.
+
+
+ 2.2. generating a fortune database
+
+ Now we come to terms. Pick a list of quotes. There are several
+ sources. Of cause the Internet will provide you with a long list.
+ Choose quotes you like they will appear regularly now. Collect the
+ quotes in one file. Every quote separated with a line containing a
+ single % e.g.:
+
+ ______________________________________________________________________
+ quote 1
+ %
+ quote 2
+ %
+ quote 3
+ %
+ quote 5
+ ______________________________________________________________________
+
+
+ This is not a very effective way. Therefor is the strfile program.It
+ will process the ASCII-file and add a binary helper. The <myquotes>
+ will accompanied by <myquotes>.dat .
+
+ ______________________________________________________________________
+
+ > strfile myquotes
+ ______________________________________________________________________
+
+
+ The <myquotes>.dat will by copied into the directory where the
+ datafiles are stored. This is usually /usr/share/fortune. Check the
+ installation with:
+
+ ______________________________________________________________________
+ >fortune myquotes
+ ______________________________________________________________________
+
+
+
+ 2.3. unstr
+
+ This is what the man-page says:
+
+ ______________________________________________________________________
+ The purpose of unstr is to undo the work of strfile. It prints out the
+ strings contained in the file source_file in the order that they are
+ listed in the header file source_file.dat to standard output. It is
+ possible to create sorted versions of input files by using -o when strfile
+ is run and then using unstr to dump them out in the table order.
+ ______________________________________________________________________
+
+
+
+ 3. other files to have fun with
+
+ An other possible target is .signature. Any selfrespecting
+ mailprogram will add that to an outgoing mail.
+
+
+ 4. remarks
+
+ The patchnames mentioned here are based on the actual fortune package.
+ Distribution may change the place to somewhere.
+
+ Beside fortune there are several other programs that select random
+ quotes from a database.
+
+ Be carefull when choosing quotes. There are people who take them
+ serious like:
