これは、区切り文字で指定されたファイル名に基づいてファイルを複数のファイルに分割するPython3スクリプトです。入力ファイルの例:
# Ignored
######## FILTER BEGIN foo.conf
This goes in foo.conf.
######## FILTER END
# Ignored
######## FILTER BEGIN bar.conf
This goes in bar.conf.
######## FILTER END
スクリプトは次のとおりです。
#!/usr/bin/env python3
import os
import argparse
# global settings
start_delimiter = '######## FILTER BEGIN'
end_delimiter = '######## FILTER END'
# parse command line arguments
parser = argparse.ArgumentParser()
parser.add_argument("-i", "--input-file", required=True, help="input filename")
parser.add_argument("-o", "--output-dir", required=True, help="output directory")
args = parser.parse_args()
# read the input file
with open(args.input_file, 'r') as input_file:
input_data = input_file.read()
# iterate through the input data by line
input_lines = input_data.splitlines()
while input_lines:
# discard lines until the next start delimiter
while input_lines and not input_lines[0].startswith(start_delimiter):
input_lines.pop(0)
# corner case: no delimiter found and no more lines left
if not input_lines:
break
# extract the output filename from the start delimiter
output_filename = input_lines.pop(0).replace(start_delimiter, "").strip()
output_path = os.path.join(args.output_dir, output_filename)
# open the output file
print("extracting file: {0}".format(output_path))
with open(output_path, 'w') as output_file:
# while we have lines left and they don't match the end delimiter
while input_lines and not input_lines[0].startswith(end_delimiter):
output_file.write("{0}\n".format(input_lines.pop(0)))
# remove end delimiter if present
if not input_lines:
input_lines.pop(0)
最後に、これを実行する方法を示します。
$ python3 script.py -i input-file.txt -o ./output-folder/
