Simple merger for flat files

merge.py

# Needed this for merging a couple of log files into one file under conditions:
# - only files of type .log needed to be merged
# - only line starting with 'RLS' needed to be merged
import os
g = open('total.txt','a')
	
for file in os.listdir('.'):
  if file.endswith('.log'):
    f = open(file,'r')
      for line in f:
        if line.startswith('RLS'):
          g.write(line)
        f.close()

g.close()
