Use the stat file I can check the file's recent modify time, and create time.

[root@controller network-scripts]# stat ifcfg-enp2s0f0
  文件:"ifcfg-enp2s0f0"
  大小:444        块:8          IO 块:4096   普通文件

Whether there is a method to list all the time that changed the file?

A normal file system does not store a change log.

How to monitor file system changes is answered here:

  • and the xxx/network-script/ifcfg-enp2s0f0 do not store the change log too? – 244boy Oct 17 '17 at 9:04

No filesystem that I know of stores every modification time. Most give you only what you have already presented: creation, last access, and last modification.


As an experiment, make a tiny partition, maybe 32M or so. Put your preferred filesystem on it, and mount this partition somewhere (I'll use /mnt for this example). Some of the available size will be taken up by filesystem data, but we can ignore that. Time is stored as a 32- or 64-bit number of seconds since some epoch; we'll assume 32 here.

32M is 33554432 bytes. 32 bits is 4 bytes, so you could store 8,388,608 timestamps on a completely empty partition. Run a loop:

for ((x=0; x < 8500000; x=x+1)); do
    touch /mnt/somefile
done

This will touch a file on the filesystem 8.5 million times (and probably take a while). Importantly, if your system is storing every timestamp, then at some point you'll get a message that the filesystem is full.
