Mayamanで作られたribを書き換える(超テキトウ)

import os
import shutil
import re
 
targetDir = 'D:/rib'
for i in os.listdir(targetDir):
	if i[-4:] != '.bat':
		continue
 
	f = open(targetDir + os.sep + i, 'r')
	o = open(targetDir + os.sep + '_' + i, 'w')
 
	for line in f:
		if re.search('RENDER_THREADS=-threads', line):
			print line
			o.write('  set RENDER_THREADS=-threads 2\n')
		else:
			o.write(line)
	f.close()
	o.close()
	os.remove(targetDir + os.sep + i)
	shutil.move(targetDir + os.sep+'_' + i, targetDir + os.sep + i )
