In this article, we will guide you through the process of cleaning the /dev/nvme0n1p2 partition on Ubuntu. This task is often necessary when the partition becomes full and you need to free up some space. Please proceed with caution as deleting the wrong files can lead to system instability or data loss.
To clean the /dev/nvme0n1p2 partition on Ubuntu, you need to check the disk usage using the df -H command, identify the files and directories taking up space using the du command, and then delete or move those files using the rm or mv commands. Be cautious when deleting files and always have a backup of important data before performing any disk cleanup operations.
Checking Disk Usage
Firstly, you need to check the disk usage of the partition. This can be done using the df -H command. This command stands for “disk filesystem” and it displays the amount of disk space used and available on the Linux filesystems. The -H option stands for “human-readable”, which means the output will be in a format that is easy to understand (like MB, GB, etc).
df -HThe output will show you the total size, used space, available space, and the mount point of the partition. For instance, for /dev/nvme0n1p2, you might see 63GB total, 42GB used, and 18GB available.
Identifying Files and Directories Taking Up Space
Next, you need to identify which files and directories are taking up space on the partition. You can use the du command for this purpose. The du command stands for “disk usage”, and it is used to estimate file and directory space usage.
sudo du -h --max-depth=1 / | sort -hIn this command, sudo is used to run the command with root privileges. The -h option is used to display the output in a human-readable format. The --max-depth=1 option is used to limit the depth of directories to which the command will descend. The / specifies the directory to start from, in this case, the root directory. The sort -h part of the command sorts the output in human-readable format.
However, this command will only show the usage of the root filesystem (/), not the specific partition. To get more detailed information, you can run the same command in other directories such as /var and /usr.
Cleaning Up the Partition
Once you have identified the directories consuming the most space, you can navigate into those directories and identify specific files or subdirectories that are taking up space.
To delete files, you can use the rm command. Be very careful when using this command, as deleting the wrong files can cause serious problems with your system.
rm /path/to/fileIn this command, /path/to/file should be replaced with the actual path to the file you want to delete.
To move files to another location, you can use the mv command:
mv /path/to/file /path/to/new/locationIn this command, /path/to/file should be replaced with the actual path to the file you want to move, and /path/to/new/location should be replaced with the path to the location where you want to move the file.
Conclusion
Cleaning the /dev/nvme0n1p2 partition on Ubuntu involves checking the disk usage, identifying the files and directories taking up space, and then deleting or moving those files. Always be cautious when deleting files, as some may be important for the system’s operation. Make sure to only remove files that are safe to delete and have a backup of important data before performing any disk cleanup operations.
For more information on disk usage in Linux, you can check out the official Ubuntu documentation.
To check the disk usage of a specific partition in Ubuntu, you can use the df -H command followed by the mount point of the partition. For example, to check the disk usage of the /dev/nvme0n1p2 partition, you can run df -H /dev/nvme0n1p2. The command will display the total size, used space, available space, and the mount point of the partition.
To identify which files and directories are taking up space on a partition, you can use the du command. Run sudo du -h --max-depth=1 /path/to/partition | sort -h to see the usage of the specified partition. Replace /path/to/partition with the actual mount point of the partition. The command will display the disk usage of each file and directory in the specified partition, sorted in human-readable format.
To delete a file using the rm command, run rm /path/to/file. Replace /path/to/file with the actual path to the file you want to delete. Be cautious when using this command, as the file will be permanently deleted and cannot be recovered.
To move a file to another location using the mv command, run mv /path/to/file /path/to/new/location. Replace /path/to/file with the actual path to the file you want to move, and /path/to/new/location with the path to the location where you want to move the file. The file will be moved to the specified location.
When deleting files on a partition, it is important to be cautious to avoid deleting important system files or data. Double-check the files you are deleting and ensure they are safe to remove. It is recommended to have a backup of important data before performing any disk cleanup operations.
