The following queries can be expressed using a BPF syntax: 8 | 9 | * Show events that happened between 01:00am and 05:00am: `hour >= 1 && hour < 5` 10 | * Show events that happened in `c:\windows\system32`: `path =~ "system32"` 11 | * Show events that happened on Saturday or Sunday: `weekday == 'Sunday' || weekday == 'Saturday'` 12 | * Show events that happened between 2018-12-01 and 2018-12-31: `date >= '2018-12-31' && date <= '2018-12-01'` 13 | * Show events that happened between 01:00am and 05:00am on Sundays or Saturday between 2018-12-01 and 2018-12-31: `(hour >= 1 && hour < 5) && (weekday == 'Sunday' || weekday == 'Saturday') && (date >= '2018-12-31' && date <= '2018-12-01)` 14 | 15 | You get the idea :) 16 | 17 | The project is still ⍺ and 👶 and is missing a few must-have features, but the killer feature is its expression engine which is ready. 18 | 19 | ## How to use it? 20 | 21 | ``` 22 | $ timeliner -h 23 | Usage of timeliner: 24 | timeliner [options] MFT.txt 25 | 26 | -color 27 | Enable color output 28 | -filter string 29 | Event filter, like "hour > 14" 30 | -strict 31 | Only show the entries maching the date restrictions 32 | 33 | $ timeliner -filter 'hour >= 1 && hour < 5' MFT.txt 34 | 2006-10-10 02:15:35: \.\Users\xxx\AppData\Local\Temp\eo117895978tm 35 | 02:16:07: \.\Users\xxx\AppData\Local\Temp\eo117895980tm 36 | 2007-05-24 03:24:43: \.\Users\xxx\AppData\Local\Temp\eo130872105tm 37 | 03:24:43: \.\Users\xxx\AppData\Local\Temp\eo113046312tm 38 | 03:24:43: \.\Users\xxx\AppData\Local\Temp\eo112784182tm 39 | 03:24:43: \.\Users\xxx\AppData\Local\Temp\eo112063273tm 40 | ``` 41 | 42 | There is a `-strict` flag to limit the output to only the matching event. For example, for one file, its modification time could be in 2015 while the creation in 2013, if we filter events after 2015: 43 | * without the strict mode, both events (in 2013 and 2015) would show up. 44 | * with strict mode, only the 2015 event would be kept: 45 | 46 | ``` 47 | $ timeliner MFT.txt 48 | 2013-04-10 08:42:37: \.\Windows\System32\winevt\Logs\Setup.evtx 49 | 2015-02-16 15:58:27:
