Put $currentDate inside the quotes. With echo it is less of an
issue, but
for many other commands you should exert more control over strings.
So as a
matter of practice:
echo "From cron@localhost $currentDate"
If nothing else it prevents filename expansion happening to the
value of
$currentDate. (Not that that will happen with the date format
chosen, but
again, as a general practice in scripting.)
In my mail files each message is followed by a blank line
before the next "From_" line. Is that a requirement of
mbox format? If so, it may be necessary to add it to
the crontab output.
Kinda. Depends on the thing parsing the mbox file. To avoid misparsing
message body lines which themselves commance with "From " some things
only consider a From_ line after a blank line. Others rely on ">"
stuffing. It is all a mess.
You _do_ need to ensure the message at least ends with a newline, of
the From_ won't be at the start of a line. So the previously posted
script ensures that with the "echo" in "( cat; echo )". If you want to
ensure a blank line you also need an additional "echo".
Working on it. Plus I have to sed in a Date: line.
Or Robert could install an MDA and make it the MDA's problem :-)
What fun would that be?
Plus I have always thought of this as a deficiency in cron on a
workstation. Cron should work (report in this case) properly without
needing something else (MTA) installed. Maybe the developers will pick
this up and do it right...
