The executable is in package fortune-mod, then there are separate packages that install extensions to it's base sentences database. In Beowulf I can find: fortunes fortunes-bofh-excuses fortunes-fr fortunes-it fortunes-it-off fortunes-mario fortunes-min fortunes-off > The idea of hashing a random aphorism is pleasant, but fortune always > displays "Misfortune!" on every invocation, which probably means it > misses a list of aphorisms not part of the package. Yes, you must install a sentences DB: [alessandro@wkstn05 ~]$ fortune What color is a chameleon on a mirror? [alessandro@wkstn05 ~]$ fortune Things are more like they used to be than they are now. [alessandro@wkstn05 ~]$ fortune O tempo é um excelente professor, mas ,infelizmente, mata todos os seus alunos. -- Hector Berlioz [alessandro@wkstn05 ~]$ fortune Avevo un fortune l'altro giorno ma l'ho scordato... [alessandro@wkstn05 ~]$ However, fortune cookie's DB is a poor source of entropy and it shouldn't be relied upon to generate secure passwords or encryption keys. It's allright to generate daily pseudo-random machine ids, though. > Also I don't understand what you mean by " * * * * * root " Man crontab(5) explaines them: Commands are executed by cron(8) when the minute, hour, and month of year fields match the current time, and when at least one of the two day fields (day of month, or day of week) match the current time (see ``Note'' below). cron(8) examines cron entries once every minute. The time and date fields are: field allowed values ----- -------------- minute 0-59 hour 0-23 day of month 1-31 month 1-12 (or names, see below) day of week 0-7 (0 or 7 is Sun, or use names) A field may be an asterisk (*), which always stands for ``first-last''. -- Alessandro Selli <[email protected]> VOIP SIP: [email protected] Chiave firma e cifratura PGP/GPG signing and encoding key: BA651E4050DDFC31E17384BABCE7BD1A1B0DF2AE
