Checking size of files/folders in Ubuntu

To see the size of the current folder in Ubuntu, you can use the du (disk usage) command. Here's how to do it:

---

1. Command to See the Size of the Current Folder

Navigate to the folder you want to analyze, then run:

du -sh

• -s: Summarize the total size of the directory.

• -h: Human-readable format (e.g., KB, MB, GB).

This will display the total size of the current folder.

---

2. See the Sizes of All Subdirectories

To list the sizes of all subdirectories along with the total size of the current folder, use:

du -h --max-depth=1

• --max-depth=1: Limits the output to the sizes of the current folder and its immediate subdirectories.

Output example:

4.0K    ./subdir1
8.0K    ./subdir2
12K     .

Here:

• subdir1 is 4 KB.

• subdir2 is 8 KB.

• . represents the total size of the current folder.

3. Sort Subdirectories by Size

If you want to see all subdirectory sizes sorted by size, you can combine du with sort:

du -h --max-depth=1 | sort -h

This will list directories in ascending order of size.

4. Analyze Hidden Files and Directories

To include hidden files and directories, use:

du -ah --max-depth=1

• -a: Displays the size of all files and directories, including hidden ones.

---

5. Graphical Method

If you prefer a graphical interface:

1. Open Files (File Manager).

2. Right-click the folder and select Properties.

3. The folder size will be displayed in the Size section.
