Linux bash script get folder size


Having an error, no space left on the device?

But you don't know which folder is consuming the most space?

Bash script below will get all the folder size and display the size for each folder.

How to use the script below?

Open your favourite terminal editor, vi, vim or other editor.

At terminal, type: vi dirfoldersize.sh

Copy and paste the code below to the editor.

Save the file.

Then make the script executable, chmod +x dirfoldersize.sh

Run the script by typing, ./dirfoldersize.sh

If everything goes well, you will get the folder size for each folder on the directory where the script runs. See sample output below.

===============
#code begins start copy below

#!/bin/bash
curdir=$(pwd)
compath="$curdir/dirlist.txt"
ls -l | grep ^d | awk '{print $9}'  > $compath


while IFS= read -r var
do


  foldersize=$(du -sh $var |awk '{print $1}')

  echo "$curdir/$var folder size: $foldersize"

done < "$compath"

#code ends, end copying from above line
  
===============
Code explanation:

#!/bin/bash == bash script header

curdir=$(pwd) == get the current working directory

compath="$curdir/dirlist.txt" == complete path plus the file name of the file

ls -l | grep ^d | awk '{print $9}'  > $compath
ls -l | grep ^d  == grab only folders or directories
awk '{print $9}' == print only column 9 which has the directory names
> $compath == save or redirect the output to the text file in compath variable

foldersize=$(du -sh $var |awk '{print $1}') == get the size of the folder in human readable for and grab the folder size only

echo "$curdir/$var folder size: $foldersize" == display a nice output for the user


Sample output:
/var/crash folder size: 4.0K
/var/cvs folder size: 4.0K
/var/db folder size: 120M
/var/empty folder size: 8.0K
/var/games folder size: 2.0T
/var/gdm folder size: 4.0K
/var/lib folder size: 137M
/var/local folder size: 4.0K



Cheers..till next time..happy scripting.
