How does linux search based on file time

This article mainly introduces linux how to search according to the file time, the article is very detailed, has a certain reference value, interested friends must read it!

Search based on file time

Each file in the Linux file system has three timestamps

Access time (- atime): the last time the user accessed the file

Modification time (- mtime): the time when the content of the file was last modified.

Change time (- ctime): the time when the file metadata (metadata, such as permissions or ownership) last changed.

-atime,-mtime,-ctime is used as a time parameter in days. You can use + to indicate greater than, and-to indicate less than.

The code is as follows:

[root@localhost] # find. -type f-atime prints out the file [root@localhost ~] # find that was accessed exactly 7 days ago. -type f-mtime + print files with a modification time of more than 7 days [root@localhost ~] # find. -type f-ctime-prints files with a modification time of less than 7 days

Similar parameters include-amin (access time),-mmin (modification time), and-cmin (change time), in minutes.

Another beautiful feature of find is the-newer parameter. We can specify a parameter file for comparing timestamps, and then find all the files that are newer than the parameter file.

Find. -type f-newer file.txt

P find all files in the current directory that take longer to modify than file.txt.
