Hi folks! I wrote utility for NILFS2 partition: n2u Repository: https://github.com/sukamenev/nilfs2_tools She's working like "svn" command. n2u can display the change history of a specific file / directory: *************** n2u log filename *************** The output is something like this: CHECKPOINT DATE TIME TYPE SIZE MODE 1787552 2019-11-24 22:08:00 first 7079 cp 1792659 2019-11-25 23:09:05 changed 7081 cp It works quite quickly for the chosen implementation method: it searches for differences between files using the bisection method, quickly mounting and comparing the file / directory in different images. You can specify a range of checkpoints using the -cp key CP1: CP2 or -cp {YEAR-MM-DD}: {YEAR-MM-DD}. You can also see the difference between the checkpoints for a specific file or directory: ************************ n2u diff -r cp1: cp2 filename ************************ You can display the entire chronology of changes: all the differences between the checkpoints of a specific file / directory: **************************** n2u blame [-r cp1: cp2] filename **************************** The date range in this command is also supported. Happy using! Sergey Kamenev
