fsock = file(filename, 'rU')
try:
# seek to end
fsock.seek(0, 2)
# get seek position
curpos = fsock.tell()
while(curpos > 0): #while not EOF
# seek ahead block_size+the length of last read block
curpos -= (block_size + len(block));
if curpos < 0:
curpos = 0
fsock.seek(curpos)
# read to end
block = fsock.read()
nl_count = block.count('\n')
# if read enough(more)
if nl_count >= lines:
break
# get the exact start position
for n in range(nl_count - lines + 1):
start = block.find('\n', start) + 1
finally:
fsock.close()
return block
list = last_lines(sys.argv, sys.argv)
if re.search("aaa", list): #查看是否包含“aaa”
print 0
else:
print 1
运行方法如下：python log.py log.txt 10 #最后10行
