Crontab entries

[Paul Lussier]

Hi all,

Is there a requirement to place parens around a set of commands
delimeted by a ';' for crontab entries?

At some point I got in the habit of creating entries like:

30 02 * * * (foo;bar;baz)

But nowhere can I find documentation even mentioning the use of
parens. Of course, I haven't even seen mention of having cron exec'ing
multiple commands either...

Using the parens definitely works, I'm just trying to figure where I
picked up that habit...

Thanks,
