Shouldn't the above be in a shell script? In this way, the commands
will be executed sequentially. Executing them concurrently does not
seem to be what you intended.

The above is a harsh way to determine whether or not cron is working. I
would use the following test instead:
*/1 * * * * date >>/tmp/date.txt

See above.
To further debug this problem, I would do one of the following:
1. set up ssmtp and set MAILTO as appropriate
2. redirect stdout and stderr to a log file
so cron can inform you of any output (i.e., errors) from the cron jobs.
BTW, what user is the crontab running under? Is it the same one as used
during the command line testing?
