Cron will email the command's output to you. Say I have a programme
called `weather`, which writes the current weather report to a file
/etc/weather. My cron command could look like this:

* * * * * weather && cat /etc/weather
(or `weather; cat /etc/weather`, if I wanted the
contents unconditionally).

Hopefully not (there is a typo). Lose the '>' before the pipe symbol
(unless you use a shell that  it -- most don't).

If chkrootkit dumps its output to the 'standard output', then you don't
can drop everything from the '>' onwards -- cron will mail the output to
you.

Try `chkrootkit | tee crk.log` instead.
(look at the man or info page for tee)

The mutt mailer can do attachments from the command line. Perhaps other
mailers can, too. If not, you may have to use MIME tools to construct a
raw mail message (but hopefully cat/tee will be sufficient).
