Hi All,
I am new to perl and just want to read the text file and write back it into another file with some modification.
Here is my requirement:

Code:
USB_OTG_PATH top.usb_top.otg_top
USB_HSIC_PATH top.usb_top.hsic_top
.. (All starts with USB_)
...
START_PATH USB_OTG_PATH.interrupt
START_PATH USB_HSIC_PATH.interrupt
..(All start with START_PATH)
requirement:
My output file should looks like the following
output file:

If I use 2 system commands in a script, will one finish before the next one starts? or will it start the first and the second at the same time?

bus_config_intr
BUS_CONFIG_INTR(9) BSD Kernel Developer's Manual BUS_CONFIG_INTR(9)NAME
BUS_CONFIG_INTR -- configure interrupt polarity and trigger mode
SYNOPSIS
#include <sys/param.h>
#include <sys/bus.h>
int
BUS_CONFIG_INTR(device_t dev, int irq, enum intr_trigger trig, enum intr_polarity pol);
DESCRIPTION
The BUS_CONFIG_INTR() method allows bus or device drivers to provide interrupt polarity and trigger mode to parent busses. This typically
bubbles all the way up to the root bus (e.g. nexus) where the necessary actions are taken to actually program the hardware. Since the
BUS_CONFIG_INTR() method takes an interrupt number, it is assumed but not necessarily required that it is called prior to BUS_SETUP_INTR(9).
The trig argument can be one of:
INTR_TRIGGER_CONFORM The interrupt trigger mode is standard for the bus to which the device is attached.
INTR_TRIGGER_EDGE The interrupt is edge triggered. This means that the interrupt is raised by the rising edge of the signal on the
interrupt line. The signal typically reverts to the original state so as to cause a spike.
INTR_TRIGGER_LEVEL The interrupt is level triggered. This means that the interrupt is raised when the signal on the interrupt line tran-
sitions and remains unchanged after that until the interrupt has been serviced, after which the signal transitions
back.
The pol argument can be any one of:
INTR_POLARITY_CONFORM The interrupt polarity is standard for the bus to which the device is attached.
INTR_POLARITY_HIGH The interrupt is activated by a high voltage on the interrupt line.
INTR_POLARITY_LOW The interrupt is activated by a low voltage on the interrupt line.
RETURN VALUES
Zero is returned on success, otherwise an appropriate error is returned.
SEE ALSO BUS_SETUP_INTR(9), BUS_TEARDOWN_INTR(9), device(9), driver(9)HISTORY
The BUS_CONFIG_INTR() method first appeared in FreeBSD 5.2.
