Well its fast

A few minor changes
I wrote a small script that calls the other as a back ground process.

cat devices.txt | while read device
do

export device
jobs
( devicev2 &)
done

This actually works wonderful. I Get the data from all 700 devices in under 1 minute. Closer to 35 seconds. There is a down side however. Both processors spike to 90 % utilization. Not to bad since it processes all the data so quickly. I have purchased a book on shell scripting and hopefully my "Style" will improve quickly.

One quick question: To limit this to 100 devices per batch (to keep from killing the processors) how would i go about doing that. I have been playing all night with different coding and I seem to get it wrong every time. A nudge in the right direction would be great.

Thanks again for all your help

LEARN ABOUT OSF1

devfs

devfs(7FS)							   File Systems 							devfs(7FS)

NAME

       devfs - Devices file system

DESCRIPTION

       The devfs filesystem manages a name space of all devices under the Solaris operating environment and is mounted during boot on the /devices
       name space.

       The /devices name space is dynamic and reflects the current state of accessible devices under the Solaris operating environment. The  names
       of all attached device instances are present under /devices.

       The content under /devices is under the exclusive control of the devfs filesystem and cannot be changed.

       The system may be configured to include a device in one of two ways:

		 By means of dynamic reconfiguration (DR), using, for example, cfgadm(1M).

		 For  devices driven by driver.conf(4) enumeration, edit the driver.conf file to add a new entry, then use update_drv(1M) to cause
		 the system to re-read the driver.conf file and thereby enumerate the instance.

       The device may be attached through a number of system calls and programs, including open(2), stat(2) and ls(1). During device  attach,  the
       device  driver typically creates minor nodes corresponding to the device via ddi_create_minor_node(9F). If the attach is successful, one or
       more minor nodes referring to the device are created under /devices.

       Operations like mknod(2), mkdir(2) and creat(2) are not supported in /devices.

SEE ALSO

       devfsadm(1M), vfstab(4), attach(9E)

NOTES

       The /devices name space cannot be unmounted.

       All content at or below the /devices name space is an implementation artifact and subject to incompatible change or removal without notifi-
       cation.
