You (the crontab owner) should get mail if the above command creates some output. Iff your
mail system isn't that broken :-). The mail destination can be set using
MAIL=other
in your crontab file. (At least vixie cron allows this.)
In absense of a working mail system you could try to save the output to
some file. Be sure that
a) this file does not exist and that the directory
is writable by the user the cron runs as. In /tmp normally this
condition should be fullfilled.
or
b) the file is writable by the user cron runs as
35 * * * * /bin/cp -f /etc/exim.conf6 /etc/exim.conf &>/tmp/log; service exim restart;
Or - if your shell (normally cron uses /bin/sh) doe'snt understand this,
you might use:
35 * * * * /bin/cp -f /etc/exim.conf6 /etc/exim.conf >/tmp/log 2>&1; service exim restart;
Another note, for "cp" you're using the full path (why?), but for
"service" you rely on the shell finding it in your PATH. Normally
"service" is "/sbin/service", and normally the PATH in your crontab
environment doesn't include any *sbin* directory. This can be set, of
course.
If you're interested in the details, please refer to crontab(5).
