    Here are some simple steps that can help you fix your Linux file system directory size issue. When listing the contents of a directory using the ls statement, you may have noticed that the specific size of directories is actually always 4096 bytes (4KB). It is the amount of space on each disk that is used to store the catalog metadata, but not what is on it.

    Note where from indicates how much space the Why directory occupies on the media, which in turn is usually larger than the total size of all files in the directory, since is from . necessary in accordance with By the size of all reliable information stored on these media, organize the directory until the format of the file system is observed.

    If the filesystem is compressible, this time of might output even less than the total size of all write data, since files can be shrunk inside the filesystem and therefore take less time to mine media than just the uncompressed information that this type of people contains. The same applies if there are few files.

    How do I find the size of a directory and subfolder in Linux?

    View the size of one or more directories, subdirectories, additional files by purchasing. Sizes are displayed as 512-byte locks. Displays the size of each list of addresses you specify, including almost all of the subdirectories below.

    If there are hard links in a directory, from offline may also matter less since the number of different files in the directory refers to the same data as the media.

    To get the direct total size of all files in the in directory, you can usually use the following one-line shell expression (assuming a GNU system):

    Search for

     . ! ! ! ! -type d -print0 | xargs -r0 stat -c% s | put -sd + | - BC 

    Search for

     . ... ... ! -type d -printf '% s  n' | Solution -sd + - | v. Chr 

    It simply divides the size of all files,non-directory, here in the directory (and its subdirectories recursively), one by one. Note that it specifies the size of the symlinks (not the symlink of the track that the symlink points to).

    Many users start Linux from the command line. However, the line of work – sometimes also called a terminal – does not have a spontaneous interface for checking disk space on Linux.

    These instructions show how to determine the size of a Linux-specific index from the administrative line.

    • Linux system
    • Command set / terminal window (available after search, login to terminal)
    • User part with sudo or root permission
    • li>

    Option 1. Show The Size Of The Entire Directory Using The Command

    How do I find the size of a directory in Linux?

    To find out the total size of a suitable directory on Linux you can use the whole (disk-usage) command.

    The of command corresponds to disk usage. This command is included by default in almost all Linux distributions.

    You can view the area of ​​the current directory by typing du at the command line:


    The machine should display a list of all the contents of your personal directory, numbered withleft. A number representing the size of the part of the object, in kilobytes. May

    You add this -h parameter to make the feature more readable:

      you -h  

    Each entry starts with a number and opening. The number is the amount associated with the space used and the detection (usually K, M or G) displays kilobytes, megabytes, gigabytes, or for example:

      400K - 800 kilobytes7.3 million - 7.3 megabytes2.2-2.2 GB  

    To size a specific directory from various shared working directories. The directives allows you to specify an important directory for -h:

    This happens when your individual user account does not necessarily have permission to access a specific directory. Use sudo or su command to gain permissions:

      sudo du -h / var  

    To find out the total disk usage in a specific important directory,use command -c :

      sudo du -c / var  

    Parameters can be grouped. If you want to repeat the new previous command in human readable format, do the following:

      sudo du -hc / var  

    You can limit the scan to a specific level of subdirectories using the maximum depth parameter. For example, to check only the size of the thinnest directory, use --max-depth = 0 :

      sudo -hc du --max-depth = 0 / var  

    If you want to display only the top directory and top-level subdirectories, edit --max-depth = 1 :

      sudo -hc du --max-depth = 1 / var  

    If you run into a problem right away or want to explore the many other options for the command, use the following command to display the help file:

    Option 2. Get The Size Of A Directory In Linux Using The Pine Command


    tree command is not included in some Linux versions. To get dressed, enter:

    • For Debian and Ubuntu
      sudo apt-get installation tree  
    • For – centos RedHat
      device tree Sudo yum updates  

    The tree view handle displays a visual representation of directories. It uses strings to indicate which subdirectories go where, and the following uses colors to identify and list files.

    Tree also allows you to have parameters. To display the readable length of the current directory subdirectories, do the following:

      tree -d -h  
      tree / var  

    This visit will take some time because there are many entries in the entire / var directory.

    Using ncdu is fun active display of trusted disk usage. For example, enter:


    In the upper left corner, the element displays the current directory that is currently being scanned. The column on the left orders numeric size, drawing between # - characters to display relative size and file or directory.

    Use the up and down arrows to select different lines. The right cursor scrolls through the directory in addition to the left arrow, which you then continue.

    ncdu can be used to grab a specific directory like:

      ncdu to the name / var  

    Press for help? in the ncdu interface. Press the letter q .


    You now have several options for determining the height and width of a directory on Linux disk systems.
