  • A Slim and Trim Linux System for You !
    A slim and trim Linux system for you ! S. Parthasarathy [email protected] ncdubuntu.odt 2018-08-12a A stitch in time … You just created a shiny new Linux system with all the bells and whistles ? Happy to see your new babe giggle and dance, as you play with her ? You want it to be the same way all the time ? It is important to do some house-keeping once a while. Over time, a computer system tends to get cluttered for many reasons. For example, software packages that are no longer needed can be uninstalled. When the system is upgraded from release to release, it may miss out on configuration tweaks that freshly installed systems get. Updating your system through the default updating tool will gradually cause the accumulation of packages and the filling of the cache. This can have a larger impact when you're uninstalling software packages and their dependencies are left behind for no reason. Over the time, you could have a dozen copies of the same file lying in different corners of your system. The best place is to hunt them down and eliminate them before they take control of the hard disk. Occasional mishaps, like unexpected disk crashes, or unintentional power failures may leave your disk with a lot of inaccessible fragments. A badly configured application may quietly chew up your disk, till there is no more free space left. Or, a runaway process or shell script may keep filling up your disk over and over again. The result could be a dramatic lockout for you.

The du clone ncdu will help slim down your data. BY CHARLY KÜHNAST use Nagios to keep track of hard- disk capacity on my server disks. IWhenever the successor to NetSaint kindly informs me that the remaining disk capacity on server XY has dropped below the magical threshold of 10%, I may be warned, but the trouble is just starting. If I’m out of luck, the whole data repository could reside on a RAID system without anything in the line of partitioning, and believe me, this is fairly typical for smaller servers. With a bit more luck, Nagios [1] might tell me that the /var partition is the bot- tleneck, leaving me to launch du and find out where the disk hogs have their megabytes stashed. Unfortunately, out- put from the Disk Usage tool for overly Figure 1: Ncdu is what du should be – it gives the user hotkeys to navigate directories and to complicated directory trees, like the ones modify the sorting order.

  • Ubuntu Server Check Free Disk Space
    Ubuntu server check free disk space The first is to use df - which according to the Ubuntu Manpage: df - report file system disk space usage Information on that can be found in How to determine where the biggest files/directories on my system are stored? The su command is completely irrelevant. The disk usage is the same for all users. Anyway, some relevant commands and their output on my. Yes, df -h (Disk Free) will show the free space on each of the mounted file Note: It's also worth running df -i to check the you haven't run out of. To check free space on a given disk/volume: Open the Disks application from the Dash. In the left pane select the disk that you want to check. In the right pane. As a system administrator, I operate a few hundred Linux servers and most of This is the most basic command of all; df can display free disk space. -x tells du to only check this file system (makes the command run faster). Your browser does not currently recognize any of the video formats available. Click here to visit our frequently. When you need to free up space on Ubuntu here are 5 simple things you can do Unlike Windows, with its built-in defrag and disk clean-up tools, Ubuntu doesn't make it immediately Run it as root, and check the boxes besides the parts you'd like to clean. This happens when you inherit over a server. In Linux, you can check disk space using command line tool called df command.
