Hi to everyone , i have a challenge right now in python that for now needs a bit of help in one part of the c0de.
The task is create a new file with the name of the file defined by the ASCII content between the 3 byte and the 16 byte that is parsed from the binary file, the file is over 20 Mb i need to create a file for each record ( each record contains the len of 820 ), so right now i know how to read it and do something with it, like :
Now the problem is , how do i get the name file that i want that is the string between the 2 byte and the 16 byte and how to save every 820 bytes to a new file like :
Code:
#attention noob code coming for quick understading i have a for loop for #example not for use i have to use it for the each 820 bytes new file
#with the read of the 820 bytes on the new file and save it and go for the
#next 820 bytes and so on until the end of the file.
for f.read(820) in file:
if f.read() = 820:
a = f.read()
b = open("Iam_from_2_to_16_byte_string", w)
b.write(a)
b.close
---------- Post updated 30-11-12 at 10:26 AM ---------- Previous update was 29-11-12 at 10:42 AM ----------
here is the solution :
Code:
n = 820
with open('/home/drdos/work/file.PDA', "rb") as f:
while True:
data = f.read(n)
if not data:
break
filename = str(data[16:32])
x = open(filename, 'wb').write(data)

This is part of my script, as you can see when the alarm is raised it shows some text, what I need it to do is to actually kill the binary "test" (TEST_PATH) when the timeout happens.

python2.7-config
PYTHON-CONFIG(1) General Commands Manual PYTHON-CONFIG(1)NAME
python-config - output build options for python C/C++ extensions or embedding
SYNOPSIS
python-config [ --prefix ] [ --exec-prefix ] [ --includes ] [ --libs ] [ --cflags ] [ --ldflags ] [ --help ]
DESCRIPTION
python-config helps compiling and linking programs, which embed the Python interpreter, or extension modules that can be loaded dynamically
(at run time) into the interpreter.
OPTIONS --cflags
print the C compiler flags.
--ldflags
print the flags that should be passed to the linker.
--includes
similar to --cflags but only with -I options (path to python header files).
--libs similar to --ldflags but only with -l options (used libraries).
--prefix
prints the prefix (base directory) under which python can be found.
--exec-prefix
print the prefix used for executable program directories (such as bin, sbin, etc).
--help print the usage message.
EXAMPLES
To build the singe-file c program prog against the python library, use
gcc $(python-config --cflags --ldflags) progr.cpp -o progr.cpp
The same in a makefile:
CFLAGS+=$(shell python-config --cflags)
LDFLAGS+=$(shell python-config --ldflags)
all: progr
To build a dynamically loadable python module, use
gcc $(python-config --cflags --ldflags) -shared -fPIC progr.cpp -o progr.so
