How to get the last modified time if the content is modified
Clash Royale CLAN TAG#URR8PPP
0
In Ubuntu if the user is not having permission to write a file but if he tries to change, the last updated time of that file will change(even after getting write error: Operation not permitted). So, I wanted the last modified time of the file if the user successfully save or modified the content is that possible.

Can you give a minimal example for the claim "the last updated time of that file will change even after getting write error". For me (16.04, ext4), this is clearly not the case. Which file system?

@RoVo actually an editor that saves a R/O file can save a new copy, remove the R/O file (possible since the parent directory is R/W) and then rename the new copy (and set it R/O). But I agree that the OP should describe the use case more clearly (even though I have little hope that there is a solution to this).

But then it is a new file, and this does not happen after a write error.

The command stat gives you that information. You can see three timestamps. Access, Modify and Change. By (succesfuly) reading the file, Access is modified. By changing for example the permissions, Change is modified. If the content is changed, Modify is changed. Take a look at this:

The command stat gives you that information. You can see three timestamps. Access, Modify and Change. By (succesfuly) reading the file, Access is modified. By changing for example the permissions, Change is modified. If the content is changed, Modify is changed. Take a look at this:
#case@maru:~/temp:[0]$ rm test
#case@maru:~/temp:[0]$ echo test>test;stat test
File: test
Size: 5 Blocks: 8 IO Block: 4096 regular file
Device: 806h/2054d Inode: 21627629 Links: 1
Access: (0644/-rw-r--r--) Uid: ( 1000/ case) Gid: ( 1000/ case)
Access: 2019-03-04 17:52:39.715956782 +0000
Modify: 2019-03-04 17:52:39.715956782 +0000

File created. All the timestamps are the same.

Can you give a minimal example for the claim "the last updated time of that file will change even after getting write error". For me (16.04, ext4), this is clearly not the case. Which file system?

@RoVo actually an editor that saves a R/O file can save a new copy, remove the R/O file (possible since the parent directory is R/W) and then rename the new copy (and set it R/O). But I agree that the OP should describe the use case more clearly (even though I have little hope that there is a solution to this).

But then it is a new file, and this does not happen after a write error.
