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.

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.
