Assume you are running short on disk space and you wanted to free up, by searching something that\u2019s a waste of space and removing it or moving it to an archive medium. How do you track down right stuff to delete, that saves maximum space?<\/p>\n

Linux provides a standard\u00a0du command<\/a>, which scans entire disk and shows you which directories hold the huge amount of data. That can assist you narrow your search to the things most useful deleting.<\/p>\n

However, that only shows you what\u2019s huge. What you actually want to know is what\u2019s too huge. By default,\u00a0du command<\/a>\u00a0will not let you differentiate between data that\u2019s huge because you are doing something that needs it to be huge, and data that\u2019s huge because you unpacked it once and ignored about it.<\/p>\n

Most Linux file systems, by default only shows\u00a0when a file was last accessed<\/a>, but not shown when it was\u00a0written, modified or even read<\/a>. So if you created a huge amount of data years ago, forgot to delete it and have never used it since, then it is important to use those last-access time stamps to know the difference between used and unused data.<\/p>\n

Agedu<\/strong>\u00a0pronounced as (age dee you<\/strong>) is an open source and free utility (much like\u00a0du command<\/strong>) that helps system administrators to track down wasted disk space used by old files and delete them to free up some space.<\/p>\n

Agedu<\/strong>\u00a0does a complete scan and produces reports that shows\u00a0how much disk space is utilized<\/a>\u00a0by 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.<\/p>\n

Agedu Features<\/h4>\n
    \n
  1. Creates graphical reports.<\/li>\n
  2. Produces data output in HTML format.<\/li>\n
  3. Generates HTML reports with hyperlinks to other directories for easy navigation to gather reports.<\/li>\n
  4. Provides more configurable options.<\/li>\n<\/ol>\n

    How Does Agedu Works?<\/h3>\n

    From the man page:<\/p>\n

    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.<\/p><\/blockquote>\n

    How to Install Agedu in Linux Systems<\/h3>\n

    On\u00a0Debian\/Ubuntu<\/strong>,\u00a0agedu<\/strong>\u00a0is available to install from the default system repositories using following\u00a0apt-get command<\/a>\u00a0as shown.<\/p>\n

    $ sudo apt-get install agedu\r\n<\/pre>\n
    On\u00a0RHEL\/CentOS<\/strong>, you need to\u00a0turn on EPEL repository<\/a>\u00a0to install\u00a0Agedu<\/strong>\u00a0using following\u00a0yum command<\/a>\u00a0as shown.<\/p>\n
    # yum install epel-release\r\n# yum install agedu\r\n<\/pre>\n
    Fedora<\/strong>\u00a0and\u00a0Arch Linux<\/strong>\u00a0users, simply type the following command to install\u00a0Agedu<\/strong>.<\/p>\n
    $ sudo dnf install agedu  [On Fedora<\/strong>]\r\n$ sudo yaourt -S agedu    [On Arch Linux<\/strong>]<\/pre>\n
    On other Linux distributions, you can compile\u00a0Agedu<\/strong>\u00a0from source as shown.<\/p>\n
    $ wget https:\/\/www.chiark.greenend.org.uk\/~sgtatham\/agedu\/agedu-20180329.af641e6.tar.gz\r\n$ tar -xvf agedu-20180329.af641e6.tar.gz\r\n$ cd agedu-20180329.af641e6\r\n$ .\/configure\r\n$ make\r\n$ sudo make install\r\n<\/pre>\n
    How to Track Wasted Disk Space Using Agedu<\/h3>\n
    The following command will do a complete scan of\u00a0\/home\/tecmint<\/strong>\u00a0directory and its sub-directories and creates a special\u00a0index<\/strong>\u00a0file containing its data structure.<\/p>\n
    # agedu -s \/home\/tecmint\/<\/pre>\n
    Scan Linux System for Disk Space<\/div>\n
    Built pathname index, 232578 entries, 22842517 bytes of index                                                                                                                \r\nFaking directory atimes\r\nBuilding index\r\nFinal index file size = 97485984 bytes\r\n<\/pre>\n
    Next, type the following command to query newly created index file.<\/p>\n
    # agedu -w<\/pre>\n
    Sample Output :<\/h5>\n
    Using Linux \/proc\/net magic authentication\r\nURL: http:\/\/localhost:34895\/\r\n<\/pre>\n
    Now, type the following command to open the\u00a0URL<\/strong>\u00a0using any web browser.<\/p>\n
    # http:\/\/localhost:34895\/<\/pre>\n
    Graphical Output :<\/h5>\n
    The below screen shows the graphical representation of disk usage of\u00a0\/home\/tecmint<\/strong>\u00a0along with its sub directories using various colors to show the difference between disused and recently accessed data.<\/p>\n
    Click on any sub directory to see the reports of its sub-directories. To terminate this mode, just press [CTRL+D<\/code>] on command line.<\/p>\n

    Let\u2019s find out how much disk space taken by\u00a0MP3<\/strong>\u00a0files by using following command.<\/p>\n
    # agedu -s . --exclude '*' --include '*.mp3'\r\n<\/pre>\n
    Again to see reports run the following command.<\/p>\n
    # agedu -w<\/pre>\n
    To deleted files and free up disk space, use the following command.<\/p>\n
    # rm -rf \/downloads\/*.mp3<\/pre>\n
    How to remove\u00a0agedu<\/strong>\u00a0index file? First see the size of the index file with the following command.<\/p>\n
    # ls agedu.dat -lh<\/pre>\n
    Sample output :<\/h5>\n
    -rw------- 1 tecmint tecmint 35M Apr 10 12:05 agedu.dat<\/pre>\n
    To remove index file, just enter.<\/p>\n
    # agedu -R<\/pre>\n
