You can use two options -hT together to get the file types in human readable format. Another useful command to find out the usage information is all files and folders.
Here, du stands for d isk u sage. This command retrieves information of folders and sub-folders and files recursively. So, this command can be used to get more detail information of disk usage. The options mentioned for df command is also applicable for du command, but the output will be different. You can also apply —help, -h and -m option with free command like previous commands. Many tools are available in Linux operating system to monitor the disk.
Some of them are built-in and some tool you will need to download and install before use. One of the mostly used built-in tool to monitor the partition of the disk is fdisk.
Using this tool you can not only monitor the disk partition but also create, move, copy and delete disk partitions. You must have root privilege to run this command.

Such chommand should definitely erase the files AND retain disk space. Leave a Reply Cancel reply Your email address will not be published. Loading Comments But even though RHEL programs usually run on the free equivalent, they often lack the certification and support from their respective vendors, which is why they are not always guaranteed to work properly with CentOS.
Depending on the respective CentOS version, different requirements are placed on the hardware. For example, CentOS 5 comes with MB of memory if you want to control it via a graphical user interface, and an economical MB if operating it via the command line is sufficient.
In addition, 5GB of storage space is recommended at least 1GB. Version 6 already requires MB for the command line variant, which is no longer available as a separate option in CentOS 7, and requires 1GB of memory on non-x86 architectures. The various releases of the RHEL derivative are also different with regard to the supported hardware architectures.
The following table gives you an overview of the possible system architectures:. The current CentOS version 7. The Linux distribution also supports hyper-threading splitting a processor into two virtual processors to increase performance , Plug and Play, Bluetooth, and version 6 of the Internet Protocol IPv6.
Compatibility libraries are available for the older CentOS 5 and 6 versions. The standard distribution package also includes the following software components:.
Further development of the Linux system was structured with the founding of the governing board. Since then, different teams — consisting of members of the diverse community — have been working in different workgroups, which either aim to expand the CentOS distribution or optimize the functional aspects of the CentOS project infrastructure, documentation, etc.
The source code makes it possible to carry out changes to the system without consulting one of these Special Interest Groups SIGs , but these may not be published under the brand 'CentOS': The individual SIGs have a certain degree of autonomy and are primarily responsible for the development process.
These groups must coordinate the development process to possible RHEL updates, and finally take care of the signing and releasing. In addition, they must develop guidelines for Git publishing and licensing. The prerequisite for projects like these is that it has to benefit the community. All additional software packages must be able to be added to the CentOS project licenses and be unpacked and issued as required.
In addition, the task of the project group is to review and, if necessary, include additional code written and released via the Git repository by other users for the particular variant. The purpose of these working groups is to make it as easy as possible for every interested user to participate in the further development. Furthermore, the purpose of these SIGs is to strengthen the community by distributing responsibilities and workloads among the active members according to their respective abilities.
This is based on the core design and is specially designed for the use of Docker containers. Further projects, which are in the planning or development stage, include the following:.
To install the open-source operating system on your own computer or server, first download the appropriate port and variant from the official download center. In addition to the current releases, you will also find setup files as well as repositories of older CentOS versions. There are three different variants available in addition to the usual full installation:.
If you have created the desired boot media , you can start the CentOS installation directly from it. Simply select the 'install CentOS' button and confirm with the [Enter] key. The graphical installer will then guide you through the rest of the process with the minimal NetInstall variant. In the list of powerful Linux descendants, CentOS is usually not one of the options that first springs to mind.
