Is there any magic to use ZSH in cron scripts ?

Is there any magic to use ZSH in cron scripts ?

[Helmut Jarausch]

Hi,
any script executed by cron is executed by the Bourne shell (on my machine,
I don't try to replace /bin/sh by zsh)

Is there any trick to use zsh?
Unfortunately

#!/bin/zsh
is not recognized when a script is executed by /bin/sh.

The only work around for me is

exec /bin/zsh << 'EOF'
....

But then
- there is an additional exec 
- the parameters to the script are lost


Is there any magic available?

Thanks for any hints,
Helmut Jarausch.

Well, you can use "zsh scriptname" in your crontab, and zsh will be
invoked.  Or, alternatively...

Try this:

exec /bin/zsh $0 "$@"

It should solve your problems.

Put your entire cron job in a script that starts "#!/usr/local/bin/zsh"
(or wherever you put it), and then have the actual crontab entry just
exec that script.
