Search & Replace regex Perl one liner to AWK one liner
Thanks for giving your time and effort to answer questions and helping newbies like me understand awk.
I have a huge file, millions of lines, so perl takes quite a bit of time, I'd like to convert these perl one liners to awk.
Basically I'd like all lines with ISA sandwiched between non-word characters on its own line
then I'd like to remove the first non-word character in front of "sandwiched" ISAs or put another way put "sandwiched" ISAs at the beginning of the line
How would I do this in awk? Thanks so much for help, I really do appreciate it. Please let me know if I can explain this more clearly or if you need data examples.

pnp
PNP(4) BSD/i386 Kernel Interfaces Manual PNP(4)NAME
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
The pnp driver first appeared in FreeBSD 2.2.5. It has been substantially updated in subsequent versions.

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