Agedu pronounced as (age dee you) is an open source and free utility (much like du command) that helps system administrators to track down wasted disk space used by old files and delete them to free up some space. But how do you track down right stuff to delete and save maximum space?

Install Agedu in Linux

Install Agedu in RHEL / CentOS / Fedora

Agedu does a complete scan and produces reports that shows how much disk space is utilized by each directory and sub directory along with the last-access times of files. In simple words, it simply helps you to free up disk space.

Agedu Features

  1. Creates graphical reports.
  2. Produces data output in HTML format.
  3. Generates HTML reports with hyperlinks to other directories for easy navigation to gather reports.
  4. Provides more configurable options.

How Does Agedu Works?

From the man page:

agedu is a program which does this. It does basically the same sort of disk scan as du, but it also records the last-access times of everything it scans. Then it builds an index that lets it efficiently generate reports giving a summary of the results for each subdirectory, and then it produces those reports on demand.

How to Install Agedu in RHEL, CentOS, Fedora

To install Agedu, you need turn on EPEL repository and run the following command to install it.

# yum install agedu

How to Scan disk using Agedu

The following command will do a complete scan of /home/tecmint directory and its sub-directories and creates a special index file contacting its data structure.

# agedu -s /home/tecmint/
Sample Output :
Built pathname index, 649 entries, 40010 bytes of index
Faking directory atimes
Building index
Final index file size = 122528 bytes

Next, type the following command to query newly created index file.

# agedu -w
Sample Output :
Using Linux /proc/net magic authentication
URL: http://127.0.0.1:35475/

Now, type the following command to open the URL using any web browser.

# http://127.0.0.1:42113/
Graphical Output :

The below screen shows the graphical representation of disk usage of /home/tecmint along with its sub directories using various colors to show the difference between disused and recently accessed data. Click on any sub directory to see the reports of its sub-directories. To terminate this mode, just press [CTRL]+[D] on command line.

748         /downloads/lynis-1.3.0

You see the output similar to du command. Let’s see the old files which are not accessed for long time. For example, to see only old files that are not accessed in last 12 months or more.

 agedu -t /downloads/ -a 12m

Let’s find out how much disk space taken by MP3 files by using following command.

# agedu -s . --exclude '*' --include '*.mp3'

Again to see reports run the following command.

# agedu -w

To deleted files and free up disk space, use the following command.

# rm -rf /downloads/*.mp3

How to remove agedu index file? First see the size of the index file with the following command.

# ls agedu.dat -lh
Sample output :
-rw------- 1 tecmint tecmint 16M Oct 27 01:22 agedu.dat

To remove index file, just enter.

# agedu -R
