Ubuntu – How to show actual size and allocated size on disk of a file in Ubuntu

diskdisk-usagefiles

I want to know both of them. It's like when you click properties of a file in Windows, it will shows two sizes (actual size and size on disk). How do I do that in Ubuntu?

I can only answer for command line.

du -b "file" gives you the actual size of the file.

du -B 1 "file" gives you the allocated size of the file on disk.

Ubuntu – Why is `df -h` not showing the whole disk space

When installed using wubi (the Windows installer) the file system is limited to 30GB max, no matter what the target partition is. If you want to use more space, in fact, if you plan on using Ubuntu for anything other then testing, do a proper installation.

Ubuntu – How to list all files and folders beyond a specified size limit

Here is a straight-forward solution in bash, which analyzes the size of both files and folders:

#!/bin/bash

folder="$1"
limit="$2"

IFS=$'\n'
for item in `find "$folder"`; do
    size=$(du -s "$item" | cut -f1)
    if [ $size -gt $limit ]; then
        echo $item
    fi
done

first param is the target folder to examine
second param is the limit in kilobytes, where 1K=1024 bytes.
