Sort Files According To Their Size

With few basic commands in Linux box, we can generate a report of files according to ascending or descending order of their size.

Let's start by displaying all the files from a folder:

find ~/testFolder -type -f 

To get their size lets pass each file to du command:

find ~/testFolder -type -f -exec du -s {} \;

Now lets sort them according to their size in numeric order, taking first column as file size and in reverse order:

find ~/testFolder -type -f -exec du -s {} \; | sort -k1nr

Let's save the output to a file size.txt:

find ~/testFolder -type -f -exec du -s {} \; | sort -k1nr > ~/size.txt
