hpoj reference: ptal-device

The ptal-device command-line utility lists device names which have been registered with "ptal-init setup".

Syntax

The syntax of ptal-device is as follows: 
	ptal-device
There are currently no command-line parameters.

Notes

Device names are listed on standard output, one per line, with no indention or other extraneous information. It is therefore useful for scripting purposes, as demonstrated by ptal-cups.

Running ptal-init with no parameters is another way to list known device names, but it provides more information so doesn't lend itself as well to scripting.

Examples

To list the device ID strings of all devices: 
for dev in `ptal-device` ; do
	echo
	echo $dev
	echo
	ptal-devid $dev
	echo
done
To set the clocks of all devices: 
for dev in `ptal-device` ; do
	ptal-hp $dev clock -set
done
