1. Preface

The Linux system has very useful commands and rich functions. If you are familiar with command-line tools, you can complete maintenance tools very efficiently.

two。 Use the stat command to view

The stat command is generally used to view the status information of a file. The output of the stat command is more detailed than the output of the ls command.

Oucanrong@zcwyou:~/iso$ stat ~ / iso/CentOS-6.10-x86_64-minimal.iso

File: / home/oucanrong/iso/CentOS-6.10-x86_64-minimal.iso

Size: 425721856 blocks: 831504 IO blocks: 4096 ordinary files

Device: 802h/2050d Inode:4471899 hard link: 1

Creation time:-

You can see that the file size is 425721856 bytes.

Linux uses the stat command to see the file size

3. Use the wc command

The wc command is generally used to count the information of a file, such as the number of lines of text and the number of bytes occupied by the file.

Oucanrong@zcwyou:~/iso$ wc-c ~ / iso/CentOS-6.10-x86_64-minimal.iso

425721856 / home/oucanrong/iso/CentOS-6.10-x86_64-minimal.iso

4. Use the du command

The du command is generally used to count the amount of space used by files and directories.

Oucanrong@zcwyou:~/iso$ du-h ~ / iso/CentOS-6.10-x86_64-minimal.iso

407M / home/oucanrong/iso/CentOS-6.10-x86_64-minimal.iso

5. Use the ls command

The ls command is generally used to view information about files and directories, including file and directory permissions, owners, corresponding groups, file size, modification time, path corresponding to files, and so on.

Oucanrong@zcwyou:~/iso$ ls-lh ~ / iso/ubuntu-18.04.1-live-server-amd64.iso

-rw-rw-r-- 1 oucanrong oucanrong 812m December 21 15:23 / home/oucanrong/iso/ubuntu-18.04.1-live-server-amd64.iso

You can see that the size of ubuntu-18.04.1-live-server-amd64.iso is 812m.

6. Use the ll command (which is actually an alias for ls-l)

In most Linux systems, the alias of ls-l has been set to ll, so there is no ll command, ll is just an alias command.

Linux uses the ll command to see the file size

Oucanrong@zcwyou:~/iso$ ll-h ~ / iso/ubuntu-18.04.1-live-server-amd64.iso

-rw-rw-r-- 1 oucanrong oucanrong 812m December 21 15:23 / home/oucanrong/iso/ubuntu-18.04.1-live-server-amd64.iso
