Linux file time

In Linux, there is no concept of file creation time. Only the file access time, modification time, state change time. This means that you cannot know when the file was created. However, if the file has not been modified since it was created, the modification time = creation time, if the state has not changed since the creation of the file, then the state change time = creation time, and if the file has not been read since it was created, then the access time = creation time, this basic is not likely.

Several times related to the file:

1, Access time, read the contents of this file, this time will be updated. For example, use the more command for this file. The LS, stat command does not modify the file access time.

2, modify the time, the contents of the file modification once, this time will be updated. For example: VI after saving files. The time that ls-l lists is this time.

3, state change time. Change the file properties once with the chmod command, and the time will be updated.

To view the detailed status of the file, the exact modification time, etc., you can use the stat command + file name. Access time. Modify modification time. Change state changes time.
