How to list directory size?

To list the size of a directory in Bash, you can use the du (disk usage) command. This command provides information about the space used by files and directories.

Basic Usage:

du -sh /path/to/directory

Explanation:

• du: The command to check disk usage.
• -s: Summarizes the total size of the specified directory.
• -h: Makes the output human-readable (e.g., KB, MB).

Example:

To check the size of a directory named project in your home directory, you would run:

du -sh ~/project

Output:

The command will return something like:

2.3M    /home/labex/project

This indicates that the project directory uses 2.3 megabytes of disk space.

If you want to see the sizes of all subdirectories within a directory, you can omit the -s option:

du -h /path/to/directory
