Was war daran so schwierig,
man -P "less +'/^EXTENSIONS'" 5 crontab
durchzulesen!? Ernst gemeinte Frage. Und ich erwarte eine Antwort darauf.
:-(
Das hier wird mir angezeigt, wenn ich die EXTENSIONS aus man 5 crontab
anschaue:

EXTENSIONS
When specifying day of week, both day 0 and day 7 will be considered
Sunday. BSD and ATT seem to disagree about this.
Lists and ranges are allowed to co-exist in the same field. "1-3,7-9"
would be rejected by ATT or BSD cron -- they want to see "1-3" or
"7,8,9" ONLY.
Ranges can include "steps", so "1-9/2" is the same as "1,3,5,7,9".
Names of months or days of the week can be specified by name.
Environment variables can be set in the crontab. In BSD or ATT, the
environment handed to child processes is basically the one from /etc/rc.
Command output is mailed to the crontab owner (BSD can't do this),
can be mailed to a person other than the crontab owner (SysV can't do
this), or the feature can be turned off and no mail will be sent at
all (SysV can't do this either).
All of the `@' commands that can appear in place of the first five
fields are extensions.
