sure here ya go:
#!/bin/sh
dmesg | less | grep -i irq | sed -e 's/^.*[iI][rR][qQ] //' | awk '{print $1}' | sort | uniq
That will show all IRQ's in use exactly the same way SCO does it.
(If a driver attached to a device; vectorsinuse displays what IRQ is in use)
Neither will catch undefined devices.
There is no reliable way to determine what hardware is using an IRQ in
software. There are plug in cards to do this but that is HARDWARE and
SOFTWARE to do the work.
