掌握 Linux 中查看文件时间的常用操作

In Linux systems, viewing the time information of files is one of the operations that developers, system administrators and even ordinary users often need to perform. File time information mainly includes three types: access time (atime), modification time (mtime) and change time (ctime). In this article, we will introduce how to obtain the time information of a file through the command line in Linux, and attach some common code examples.

1. View the access time of the file (atime)

The access time refers to the last time the file was accessed. To view the access time of a file, you can use the stat command in combination with the awk command to extract time information. Examples are as follows:

stat -c %x filename.txt
Copy after login

2. View the modification time of the file (mtime)

The modification time refers to the time when the file was last modified. To view the modification time of a file, you can also use the stat command. The example is as follows:

stat -c %y filename.txt
Copy after login

3. View the change time of the file (ctime)

The change time refers to the file The time when metadata (such as file permissions, user ownership, etc.) was last modified. Also use the stat command, the example is as follows:

stat -c %z filename.txt
Copy after login

4. Comprehensive example: View all time information of the file

If you want to view all time information of the file at one time, you can Use the following command:

stat filename.txt
Copy after login

This command will output the access time, modification time, change time and other detailed information of the file.

5. View file time information in batches

If you need to view the time information of multiple files in batches, you can use the find command in conjunction with the stat command , examples are as follows:

find . -type f -exec stat -c "%n %x %y %z" {} ;
Copy after login

Conclusion

Through the introduction of this article, I hope readers can master the common operations of viewing file time information in Linux systems. Proficient use of these commands can help you better manage and maintain files. Of course, in actual operation, you can also further customize and expand the commands according to specific needs. Good luck working on your Linux system!
