Dear Monks
I have a big text file (200 MB) with the following structure: it has 100 reviews, each review with 5 formulas, and each formula (f) iterate 19200 times according with the values I passed, which will the same for review 2 and so on.
Review 1

f: 1 total: 30 values: 50: 20: 0: 0 ...
f: 1 total: 30 values: 50: 25: 4: 4 ...
f: 1 total: 30 values: 55: 45: 8: 6 ...
... (19200 f1 total for review 1)

f: 4 total: 250 values: 50: 20: 0: 0 ...
f: 4 total: 320 values: 50: 25: 4: 4 ...
f: 4 total: 330 values: 55: 45: 8: 6 ...
... (19200 f4 total for review 1)

Review 2

f: 1 total: 20 values: 50: 20: 0: 0 ...
f: 1 total: 30 values: 50: 25: 4: 4 ...
f: 1 total: 45 values: 55: 45: 8: 6 ...
... ... (19200 f1 total for review 2)

f: 3 total: 250 values: 50: 20: 0: 0 ...
f: 3 total: 320 values: 50: 25: 4: 4 ...
f: 3 total: 330 values: 55: 45: 8: 6 ...
...... (19200 f3 total for review 2)

My questions is how can I split the file in 19200 text files in one directory, each file with the same 100 reviews, and 5 formulas but each file refering a specific values used in the formula (f)
Example = File00001.txt: with the formula using values 50:20:0:0
Review 1
f:1 total: 30 values: 50: 20: 0: 0 ...
f:2 ... f:4 total: 250 values: 50: 20: 0: 0 ...
Review 2
f:1 total: 20 values: 50: 20: 0: 0 ...
f:2 ... f:3 total: 250 values: 50: 20: 0: 0 ...

File00201.txt:
Review 1
f:1 total: 30 values: 50: 25: 4: 4 ...
f:2 ... f:4 total: 320 values: 50: 25: 4: 4 ...
Review 2
f:1 total: 30 values: 50: 25: 4: 4 ...
f:2 ... f:3 total: 320 values: 50: 25: 4: 4 ...
f:4 ...

File00301.txt:
Review 1
f: 1 total: 30 values: 55: 45: 8: 6 ...
f: 4 total: 330 values: 55: 45: 8: 6 ...
Review 2
f: 1 total: 45 values: 55: 45: 8: 6 ...
f: 3 total: 330 values: 55: 45: 8: 6 ...
Using a regular expression will be enough?, Should I delete the blank spaces and iterate 19200 + including titles, and split?
Thank you in advance for your help
