Check folder size in Bash

Question

I\'m trying to write a script that will calculate a directory size and if the size is less than 10GB, and greater then 2GB do some action. Where do I need to mention my fol

Answer 1

To just get the size of the directory, nothing more:

du --max-depth=0 ./directory

output looks like

5234232       ./directory

Answer 2

If it helps, You can also create an alias in your .bashrc or .bash_profile.

function dsize()
{
    dir=$(pwd)
    if [ "$1" != "" ]; then
            dir=$1
    fi
    echo $(du -hs $dir)
}

This prints the size of the current directory or the directory you have passed as an argument.
