Cronjob on Irix 6.2

[uncletom]

Hi,
I want to create a cron job which checks every minute of every hour if a file called "plotf" exists or not. If that file exists, a process called "plot_file" should start, otherwise nothing should happen.
Who knows the syntax for the line in the cronfile:

0-59 0-23 * * * if ???? Then /plot_file; fi

or something like that ??
Thnx.

I've used something like this:
* * * * * if test -w /plotf; then plot_file; fi

But I prefer to use a script that starts a plot process after sending the plot file.
