Public bug reported:
The manual for crontab(5) shows various examples of using the date command as
such:
$(date +%u)
This contradicts the note specifying that any % sign needs to be escaped
Entering something like that as a command for execution fails to
interpret anything past the % sign.
so, for example:
* * * * * echo $(date +%Y)
fails with
/bin/sh: 1: Syntax error: end of file unexpected (expecting ")")
The syslog shows this
CRON[10104]: (root) CMD (echo $(date +)
Simply escaping the % resolves it, so in this example, the manual should
be updated so that each 'date' example looks as
$(date +\%u) - or whatever the format character example is.
My example cron from above executes as expected as
* * * * * echo $(date +\%Y)
which send me an email simply with "2013"
