從一個巨大的日誌文件中僅提取 GPS 位置到以日期標記命名的新文件
所以,我有巨大的(超過 10 萬條記錄)日誌文件,並且需要根據它們的日期戳提取所有 GPS 位置。
./production.log.109.gz:I, [2022-02-10T10:00:59.703529 #25190] INFO -- : #<Event::TeltonikaServer:3ffcbe931d90>:357544377733734 TS: 2022-02-10 10:00:35 +0000, GPS: 52.1773033,20.8162, SAT: 17, KM/H: 0, V: 26343 ./production.log.109.gz:I, [2022-02-10T10:01:13.939349 #25190] INFO -- : #<Event::TeltonikaServer:3ffcbe931d90>:357544377733734 TS: 2022-02-10 10:00:40 +0000, GPS: 52.1773033,20.8162, SAT: 17, KM/H: 0, V: 26352 ./production.log.109.gz:I, [2022-02-10T10:10:44.757308 #25190] INFO -- : #<Event::TeltonikaServer:3ffcbe931d90>:357544377733734 TS: 2022-02-10 10:10:40 +0000, GPS: 52.1773033,20.8162, SAT: 18, KM/H: 0, V: 25924
因此,基本上,對於我需要找到的那 3 條記錄
10th February 2022
,將兩個圖章剪切並粘貼"GPS:"
到名為 的新文件2022-02-10.txt
中,或者最好粘貼到合適的.KML
文件中。
每個事件都在單獨的行中,因此您可以逐行讀取並用於在之後和之後
regex
查找文本- 然後您可以用作文件名並寫入TS:``GPS:``TS``append mode
最小的工作範例。
我只用
io
withtext
來模擬記憶體中的文件,但你應該使用open()
text = '''./production.log.109.gz:I, [2022-02-10T10:00:59.703529 #25190] INFO -- : #<Event::TeltonikaServer:3ffcbe931d90>:357544377733734 TS: 2022-02-10 10:00:35 +0000, GPS: 52.1773033,20.8162, SAT: 17, KM/H: 0, V: 26343 ./production.log.109.gz:I, [2022-02-10T10:01:13.939349 #25190] INFO -- : #<Event::TeltonikaServer:3ffcbe931d90>:357544377733734 TS: 2022-02-10 10:00:40 +0000, GPS: 52.1773033,20.8162, SAT: 17, KM/H: 0, V: 26352 ./production.log.109.gz:I, [2022-02-10T10:10:44.757308 #25190] INFO -- : #<Event::TeltonikaServer:3ffcbe931d90>:357544377733734 TS: 2022-02-10 10:10:40 +0000, GPS: 52.1773033,20.8162, SAT: 18, KM/H: 0, V: 25924 ''' import io import re # open file for reading #file_in = open("filename.log") file_in = io.StringIO(text) # read line by line for line in file_in: # find values ts = re.findall('TS: ([^ ]*) ', line)[0] gps = re.findall('GPS: ([^ ]*), ', line)[0] val = gps.split(',') gps = f'{val[1]},{val[0]}' print('TS:', ts, '| GPS:', gps) # open file for writing in `append mode` with open(f'{ts}.txt', 'a') as file_out: # write in new line file_out.write(gps + '\n')
結果:
TS: 2022-02-10 | GPS: 20.8162,52.1773033 TS: 2022-02-10 | GPS: 20.8162,52.1773033 TS: 2022-02-10 | GPS: 20.8162,52.1773033
KML
是更複雜的格式(使用XML
結構),我不會嘗試編寫它。但是有 Python 模組可以寫入
KML
- 即。簡單的它可能沒有附加到文件的功能,因此首先它可能需要獲取所有值 GPS,按數據分組,然後為每個組創建 KML 並一次保存所有點。
