![]() head command : Output the first part of files i.e.sort command : Sort lines of text files or given input data.du command : It estimates file space usage.This article will help you to use Unix and Linux commands for finding the most important or biggest files or directories on the file systems.Īlthough, there is no shortcut command which is available to discover the largest documents/directories on a Linux/UNIX/BSD file system but there is a possibility which we will be showcasing you about.īy aggregating the following three commands (the use of pipes) can help you easily discover a list of largest documents on a Linux machine. Similarly, we should be able to discover a particular directory location on file system such as /tmp/ or /var/ or /domestic/.

One such application is called QDirStat, but it may not be installed by default on your Linux distro. Sometimes it’s easier to visualize disk usage if we use a GUI utility. Using the find command, and optionally the sort and head commands should help you find all the biggest files in a directory, or on your entire system. size +2G -exec ls -sh1 + | sort -r -h | head -3 The -h option is for human-readable, and is necessary if we’re using the same -h option in the ls command. Notice the -r option for sort, which will instruct it to list biggest files at the top. That’s where the sort command becomes helpful. If we have a lot of returned results, it can be difficult to see which ones are the biggest. One problem with the previous example is that the files aren’t sorted by size.manjaro-kde-20.1.2-201019-linux58.isoĪs you can see, this output is much more helpful in identifying large files than the previous examples. This will search for files greater than 2GB, while showing us the size of the files.Ĩ.2G. Using the following command, we can execute the ls command whenever find comes across a file matching our criteria. One problem with the find command in this case is that it doesn’t reveal the file sizes of the files it finds.For example, let’s locate files that are between 2GB and 5GB. The + and - parameters can be used in tandem to search for files in a certain size range.We can also use the - symbol to search for files under a certain size.We use the + to specify “greater than” and a G for gigabytes. This command will look for files that are greater than 5GB in size.This command will look for files that are 100MB in size.Of course, you may specify any directory that you wish to search, and find will recursively search for the files you want. Note that in the following examples, we’ll use find to search our present working directory, which is represented as. find has options that can be used to find files based on file size. The best Linux command we have at our disposal to locate large files is the find command. $ – requires given linux commands to be executed as a regular non-privileged user # – requires given linux commands to be executed with root privileges either directly as a root user or by use of sudo command Privileged access to your Linux system as root or via the sudo command.
