![]() Disk blocks read and written is available as a statistic, but has little or no relation to disk space used, as the same block could be read and written multiple times, and this statistic also includes I/O from swap and demand paging. From any directory just type df and hit enter, it will quickly return some results and exit. This is run on your behalf, however, so the usage data is quickly compiled and presented. xdiskusage Another block-based graphical usage analyzer, xdiskusage has a quite basic UI and gathers information from the du command. What would disk space by process mean? Do you mean size of the executable? Size of the executable and shared libraries? Size of the open files? None of these belong to a single process, but are shared between all processes that use those files. To find out how much space you have left we can run the df command. Having said that, Disk Usage Analyzer is easy to use and ideal for quick checks of usage without too much involvement. Note that disk space utilization by process doesn't make sense, because processes don't use disk space, files do. The atop command will also show similar statistics to what iostat shows, but if run as root in disk mode (press d), will show disk I/O utilization by process. By default, it shows averages since boot, but can also be given a time interval and show what happened during that interval. Since you may come here while searching for a quick Linux command to free some disk space, I am first listing commands you can use, Ill explain it in the next. The syntax is as follow: duWith the du command, you need to specify which folder or file you want to check. ![]() It will show you details about the disk usage of files and directories on a Linux computer or server. Another important command is du, short for Disk Usage. The iostat command shows total live disk activity on each disk. There are two main commands when it comes to checking disk space and filesize (/directory size): df and du. Check Disk Usage in Linux Using the du Command. The du command summarizes total disk use by directory and file.Äisk I/O bandwidth use over a time interval which can be displayed with tools like iostat and atop. The df command summarizes total disk size, use, and free space by mounted partition. There are two meanings for disk usage here.Äisk disk space usage is summarized by the du and df commands.
