PNPINFO(8) BSD System Manager's Manual PNPINFO(8)NAME
pnpinfo -- reports information about Plug-n-Play ISA devices
SYNOPSIS
pnpinfo
DESCRIPTION
pnpinfo reports information about Plug-n-Play ISA devices. Some of the information, such as the vendor ID, serial number, I/O ports, IRQ,
etc. are useful when configuring a kernel with ISA PnP devices.
SEE ALSO pnp(4)HISTORY
The pnpinfo utility first appeared in FreeBSD 2.2.

BUGS
A few of the tags are unimplemented (Enough exist for 99% of PnP cards).

pnp -- support for ``Plug and Play'' (PnP) ISA devices
DESCRIPTION
The pnp driver enumerates ISA devices which support ``Plug and Play ISA Specification'' in the system. It assigns ISA bus resources (inter-
rupt line, DMA channel, I/O ports, and memory region) to each device and activates it.
If it cannot assign necessary resources to a PnP ISA device without causing conflict with other devices in the system, the device will not be
activated and will be unavailable to programs.
CAVEATS
It is not possible to disable individual PnP ISA devices. The pnp driver will find all devices conforming the PnP ISA specification and try
to activate them all.
There is no way to explicitly assign particular resource to the PnP ISA device. The resource assignment is fully automatic and there is no
provision for manual override.

HISTORY

PnP support was originally written for FreeBSD 2.2.5 by Luigi Rizzo, based on initial work done by Sujal Patel.

Originally, we only had one shell on unix. When ran a command, the shell would attempt to invoke one of the exec() system calls on it. It the command was an executable, the exec would succeed and the command would run. If the exec() failed, the shell would not give up, instead it... (3 Replies)

I have seen some misinformation regarding Unix file permissions. I will try to set the record straight. Take a look at this example of some output from ls:
$ ls -ld /usr/bin /usr/bin/cat

Suppose I have a main() function with only one malloc statement allocating say some 1 gb memory. Also say my system has 1 gb of ram.
main()
{
malloc(1gb)
return(0)
}
The program above exits without freeing the memory.
In this case will the 1 gb of heap memory be returned... (9 Replies)
I see lot of ad-hoc shell scripts in our servers which don't have a shebang at the beginning .
Does this mean that it will run on any shell ?
Is it a good practice to create scripts (even ad-hoc ones) without shebang ? (16 Replies)

So, I am starting looking into the world of UNIX for a new job (luckily not my primary function!) and I am looking to get stared. Like anything I seem to learn best by trying things out first in an environment but I have a key question:
