Here are some advantages to use du command to check file size in Linux. If you want du to check the sizes of all files and subdirectories within “mydir”, you can use the “-sh” option: It can be used to find out not only the size of a given file, but also the size of a directory.įor example, to check the size of the file “myfile.txt”, you would type: Enter the command du /home/howtouselinuxĤ096 /home/howtouselinux/.mozilla/pluginsĤ.0K /home/howtouselinux/.mozilla/pluginsĤ.0K /home/howtouselinux/.mozilla/extensionsĭu is a command line utility for estimating file space usage. To find out the disk usage summary of a /home/howtouselinux directory tree and each of its subdirectories. This is the most efficient way to get the size of a directory in du -sh /home/howtouselinux This will give you a total size for the directory, rather than listing the size of each individual file and subdirectory within it. If you need to get the size of a directory in Linux, use du -sh command. It can be used to check the disk usage of files and directories on Linux system.

It offers many helpful options individually or in the correct combinations.ĭu -h option will print file size in human readable format (e.g., 1K 234M 2G). The du command summarizes disk usage of each file and recursively for each directory.
