Thanks hth.

1. The script is hard coded, no environment variables.

2. Yes. sudo su - then crontab -e. I've also tried it using Mac OS X's Launchd, which is their cron replacement since they do state that they are deprecating cron. But it didn't make a difference.

3. I should have been more clear about the behavior. The problem is that the hosts files in the NFS dir can't be read. The [ -f .../hosts] test works fine, so the script can access the NFS directory and see that the file exists, but the cat command can't read the actual file. The hosts.base is moot. If I just simply try to "cat /.../nfs/hosts > /etc/hosts" then I end up with a 0 sized /etc/hosts file.

Somehow Mac OS X Catalina is executing the script in some sort of environment differently depending on whether it is launched manually, or from cron/launchd.

HOBBIT-HOSTGRAPHS.CGI(1)				      General Commands Manual					  HOBBIT-HOSTGRAPHS.CGI(1)

NAME

       hobbit-hostgraphs.cgi - CGI program to show multiple graphs

SYNOPSIS

       hobbit-hostgraph.cgi

DESCRIPTION

       hobbit-hostgraph.cgi is invoked as a CGI script via the hobbit-hostgraph.sh CGI wrapper.

       If no parameters are provided when invoked, it will present a form where the user can select a time period, one or more hosts, and a set of
       graphs.

       The parameters selected by the user are passed to a second invocation of hobbit-hostgraph.cgi, and result in a webpage showing  a  list	of
       graph images based on the trend data stored about the hosts.

       If multiple graph-types are selected, hobbit-hostgraph.cgi will display a list of graphs, with one graph per type.

       If  multiple  hosts  are  selected,  hobbit-hostgraph.cgi will attempt to display a multi-host graph for each type where the graphs for all
       hosts are overlayed in a single image, allowing for easy comparison of the hosts.

       The hostlist uses the PAGEPATH cookie provided by Xymon webpages to select the list of hosts to present. Only the hosts visible on the page
       where hobbit-hostgraph.cgi is invoked from will be visible.

       The resulting graph page can be bookmarked, but the bookmark also fixates the time period shown.

OPTIONS

       --env=FILENAME
	      Loads the environment defined in FILENAME before executing the CGI script.

BUGS

       This utility is experimental. It may change in a future release of Xymon.

       It is possible for the user to select graphs which do not exist. This results in broken image links.

       The set of graph-types is fixed in the server/web/hostgraphs_form template and does not adjust to which graphs are available.

       If the tool is invoked directly, all hosts defined in Xymon will be listed.
