Can you check the total size of files in linux?

Linux can view the total size of the file. How to check the total size of the file: 1. Use the stat command with the syntax "stat file path". The Size field in the third line of the output result is the number of bytes of the file; 2. Use the wc command with the syntax "wc -c file path". ", you can output the number of bytes, words, and lines in the specified file; 3. Use the du command with the syntax "du -h file path" to display the file size in customary units; 4. Use the ls command with the syntax "ls -lh file path".

Linux can view the total size of the file.

Linux has a variety of built-in commands to check the file size. Let’s take a look.

1. stat command

The stat command is used to display the status information of the file. Syntax:

stat filepath

The output information of the stat command is more detailed than the output information of the ls command. The information that can be viewed with the stat command includes:

• File: Displays the file name

• Size: Displays the file size

• Blocks: Total number of data blocks used by the file

• IO Block: IO block size

• regular file: File type (regular file )

• Device: Device number

• Inode: Inode number

• Links: Number of links

• Access: File permissions

• Gid, Uid: Gid and Uid of file ownership

• Access time: Indicates the time when we last accessed (only accessed, no changes) the file

• modify time: Indicates the time when we last modified the file

• change time: Indicates the time when we last changed the file attributes, including permissions, size, attributes, etc.

• Birth time: file creation time, crtime, but according to the investigation This attribute has been deprecated in linux, and the current status display results are -

Example: Check the size of the jdk-8u60-linux-x64.tar.gz file

stat ~/Downloads/jdk-8u60-linux-x64.tar.gz

The Size field in the third line is the number of bytes in the file

2. The wc command

The function of the wc command is to count the words in the specified file The number of sections, words, and lines, and the statistical results will be displayed and output. If the file name is not specified, or the file name given is "-", the wc command will read data from the standard input device

wc -c filename

Parameter -c: Indicates statistical characters, because one character is one byte, so the number of bytes is obtained

Example: Check the size of the jdk-8u60-linux-x64.tar.gz file

wc -c  ~/Downloads/jdk-8u60-linux-x64.tar.gz

3. du command

du is a command that counts the disk space occupied by a directory or file.

Syntax of counting in bytes

du -b filepath

Parameter -b: Indicates counting in bytes

Example:

du -b  ~/Downloads/jdk-8u60-linux-x64.tar.gz

Or directly get the file size recognized by Renhao

du -h filepath

• -h: Use custom units to display disk usage, such as KB, MB or GB, etc.;

Example:

du -h  ~/Downloads/jdk-8u60-linux-x64.tar.gz

If du is executed on a directory, du will recursively list the directories of all files and display their sizes, as well as the sizes of all files in the directory. If we want to know the total size of all files in a directory, execute:

du 目标目录 -sh

• -s, --summarize display only a total for each argument

• -h, --human-readable print sizes in human readable format (e.g., 1K 234M 2G)

4. ls command

ls command , the abbreviation of list, is the most common directory operation command, and its main function is to display the contents of the current directory. The file size can be listed with some options

ls -l filepath

The fifth column of the output is the number of file bytes

Example:

ls -l  ~/Downloads/jdk-8u60-linux-x64.tar.gz

ls -lh filepath

• h means human, add the -h parameter to get the file size that is easy for humans to read

ls -lh  ~/Downloads/jdk-8u60-linux-x64.tar.gz
