cron: sending output to file then EMAILing file to me - email

Question

I am writing a series of cron jobs. I want each task to log its output to file, and then I want the contents of the file mailed to me at say me#somewhere.com
I think logging the output to file can be done using simple pipe redirection like this:
30 0 * * * /path/to/script1 > task1.log
30 1 * * * /path/to/script2 > task2.log
However, I am not sure how to mail the files (or simply their contents) to me in seperate emails to me#somewhere.com
Also, is there a way to dynamically create the log file names, based on the date, so that the log names would be something like %Y%m%d.task1.log ?
Where the prefix is the date ?
I am running on Ubuntu 10.0.4 LTS

If your system has a working /usr/bin/sendmail (doesn't have to be sendmail sendmail, most mail servers provide a /usr/bin/sendmail wrapper script) then you can use the mail(1) utility to send mail:
echo "hello world" | mail -s hello me#example.com
mail(1) is pretty primitive; there's no MIME file attachments, you're stuck with plaintext.
If mutt(1) is installed, you can use MIME to attach files:
echo "hello world" | mutt -a task*.log -- me#example.com
As for giving the logfiles dates:
$ echo "hi" > $(date "+%Y%m%dlog.txt")
$ cat 20110328log.txt
hi
$
So, try this:
30 1 * * * /path/to/script2 > $(date "+\%Y\%m\%dlog.txt") && mutt -a $(date "+\%Y\%m\%dlog.txt") -- me#example.com
