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.

dfmounts_nfs

dfmounts_nfs(1M)					  System Administration Commands					  dfmounts_nfs(1M)

NAME

       dfmounts_nfs - display mounted NFS resource information

SYNOPSIS

       dfmounts [ -F nfs] [-h] [server...]

DESCRIPTION

       dfmounts  shows	the local resources shared through  NFS, along with the list of clients that have mounted the resource. The -F flag may be
       omitted if  NFS is the only file system type listed in the file	/etc/dfs/fstypes.

       dfmounts without options, displays all remote resources mounted on the local system, regardless of file system type.

       The output of dfmounts consists of an optional header line (suppressed with the -h flag) followed by a list of lines containing whitespace-
       separated fields.  For each resource, the fields are:

       resource server pathname clients ...

       where

       resource        Does not apply to  NFS.	Printed as a hyphen (-).

       server	       Specifies the system from which the resource was mounted.

       pathname        Specifies the pathname that must be given to the share(1M) command.

       clients	       Is a comma-separated list of systems that have mounted the resource.

OPTIONS

       -F nfs	       Specifies the nfs-FSType.

       -h	       Suppress header line in output.

       server	       Displays  information  about  the resources mounted from each server, where server can be any system on the network.  If no
		       server is specified, the server is assumed to be the local system.

FILES

       /etc/dfs/fstypes
