Use the find command in linux to find files based on system time

This article describes how to use the find command to search for files based on the timestamp of your system. For more information, see LinuxFind

These timestamps include

Copy codeThe code is as follows:
Last modification time of mtime file content
Time when the atime file is read or accessed
Ctime file status change time

Mtime and atime are both easy to understand, while ctime requires more explanations. Inode maintains the metadata of each file. Therefore, if the metadata related to the file changes, the inode data also changes. This may be caused by a series of operations, including creating symbolic links to files, changing file permissions, or moving files. In these cases, the file content will not be read or modified, so mtime and atime will not change, but ctime will change.

These time options must be used together with a value of n, specified as-n, n or + n.

Copy codeThe code is as follows:
N * 24
+ 1 indicates 1x24 + 24 hours away ..
+ 0 indicates 0x24 + 24 hours away
1 indicates the range from 1x24 + 24 to 24 ..
0 indicates 0*24 + 24 to 0 ..
-1 indicates 0*24 + 24, or even the future time...

1. Current time: 24 hours-current time (yesterday-today)
# Find.-mtime 0
2. Current Time 48 hours ago-current time 24 hours ago (the day before yesterday)
# Find.-mtime 1
3. the current time is 48 hours ago (2 days ago)
# Find.-mtime + 1
4. Current time: 24 hours-current time (yesterday-today)
# Find.-mtime-1
