How to check disk space in Ubuntu?
The easiest way to check available disk space in Ubuntu is by using the du command. The du command stands for “disk usage” and can be used to check the amount of disk space a given directory is taking up. To check the overall disk space, you can run the following command: $ du -h --max-depth=1 / This will show the total disk space in “human-readable” format, which should make it easier to read. You can also run the du command without the “-h” to get the output in bytes. For more specific results, you can run the same command on individual directories within your system. For example, to check the disk space of your home directory, you could run the following command: $ du -h --max-depth=1 ~/ This will give you the amount of disk space being used in each directory of that path.To check the available storage space in Ubuntu, open the terminal and type in “df -h” to view a list of your storage partitions and the available space on each. Alternatively, you can also use the “Disk Usage Analyzer” tool which is a graphical application that provides a summary of the available and used disk space in Ubuntu.1. On Windows: a. Open the Start menu and type “This PC.” b. Select This PC and locate your hard drive. c. Right-click the hard drive and select “Properties.” d. You will see how much hard disk space you have available. 2. On Mac OS X: a. Open the Apple menu and select “About This Mac.” b. Click the Storage tab. c. You will see how much hard disk space you have available.You can find out how much disk space is remaining on a Windows computer using the Disk Management tool. Open the tool by pressing Windows Key + R, and type "diskmgmt.msc". This will open the Disk Management window, which will show each drive and the amount of space used and remaining. On a Mac computer, go to the Apple Menu in the upper-left corner, then select About This Mac. Click the Storage tab to view the remaining disk space for each drive.1. Use the Finder “About This Mac” Option: - Open the Finder and select “About This Mac” from the Apple menu at the top left of the screen. - Select the “Storage” tab and then scroll through the list to see what’s taking up the most space. - Delete or move any large files or folders to another location to free up space. 2. Empty the Trash: - Check the Trash for large files that have been deleted but not emptied. - Empty the Trash to free up space. 3. Uninstall Unnecessary Apps: - Go to the Applications folder and delete any apps that you no longer need or use. - This can help free up some storage space on your startup disk. 4. Clear Your Cache: - Certain applications may store a lot of data in their caches. - Go to each application and look for the “clear cache” or “delete cache” option. 5. Enable Optimize Storage: - If you’re running macOS 10.12 or later, you can enable the “Optimize Storage” option to automatically free up space. - This will delete any old files and redundant data as needed, as well as storing some data in iCloud.

Install the NTP package: To install the Network Time Protocol (NTP) package, open a terminal window and type in the following command. For Debian/Ubuntu: sudo apt-get install ntp For Red Hat/CentOS/Fedora: yum install ntp 2. Configure NTP: Once the package has been installed, edit the /etc/ntp.conf configuration file using your favorite editor. In the file, you will find a list of NTP servers that have been pre-configured. These servers will be used to synchronize the time of your system to the global time source. You can add or remove servers from this list. However, it is recommended to use at least three servers. Once you have updated the list of servers, save the file and restart the ntp service by running the following command: For Debian/Ubuntu: service ntp restart For Red Hat/CentOS/Fedora: systemctl restart ntpd For further help, refer to the NTP documentation which explains how to configure advanced settings, such as allowing access to your NTP server from remote computers.1. Install an NTP server package that is compatible with your operating system. 2. Configure the NTP server with the appropriate time zone settings. 3. Choose at least two servers from the public NTP server pool and set them up as your external time sources - you can obtain a list of valid options from the NTP pool project website. 4. Configure your firewall to allow incoming NTP requests from your external servers. 5. Set up an NTP client to query the servers for time synchronization. 6. Enable the NTP daemon on your server so that it can accept incoming requests from other clients. 7. Configure logging to monitor server performance and usage. 8. Update the NTP server with the latest security patches.On Linux, you can use the command line utility called `ntpq` to check the system's current NTP configuration. The `ntpq` command returns information such as the NTP server, version number, stratum, status, time offset, and more.
