Split a single file into multiple files

[neeru29]

I have file with 1000 lines. for example:
..
..
01-06 00:02:33.459 I/Activity( 32): Starting: {....APTPower}
..
..
..
..
01-06 00:02:34.563 I/Activity( 32): Starting: {....APTPower}
...
...
..
..
01-06 00:03:21.459 I/Activity( 32): Starting: {....APTPower}
..
..
I want to split file where ever Starting & APTPower occurs and writing it to new file until next occurance of pattern i.e., starting & APTPower.

How do i do that?

First you should decide on how to name the files you are writing to. I would suggest a starting name and increment the name from there. Something like:

>>> for i in range(10):
... 	fn = "filename%s" % (i)
... 	print fn
... 	
filename0
filename1
filename2
filename3
filename4
filename5
filename6
filename7
filename8
filename9
>>>

Iterate on the open file object and test each line for membership of keywords. When both keywords are in the line, close the open file object for writing and open a new one.

fread = open("data11.txt")
count = 1
fwrite = open("filename%s" % (count), 'w')
for line in fread:
    if "Starting" in line and "APTPower" in line:
        # close open file object, increment count, open new file object
        fwrite.close()
        count += 1
        fwrite = open("filename%s" % (count), 'w')
        fwrite.write(line + "\n")
    else:
        fwrite.write(line + "\n")
fwrite.close()
fread.close()
