To install the tar utility on a Red Hat Enterprise Linux (RHEL) or CentOS 6/7/8 system using the yum package manager, you can use the following command:
sudo yum install tar
This command will install the tar package, which includes the tar command-line utility for creating and extracting archive files.
Alternatively, you can use the following command to install the tar package:
sudo yum install -y tar
It will also install any dependencies that the tar package may require.
Once the installation is completed, you can use the tar command to create and extract archive files. For example, to create an archive of a directory named “mydir,” you would use the following command:
tar -cvf mydir.tar mydir
And to extract the contents of the archive, you would use the following command:
tar -xf mydir.tar
You can also use other options with tar command as per your requirement.
It’s important to note that if you’re using a version of CentOS/RHEL that’s older than 6, the version of tar that’s provided by the package manager may not include all of the features and options of more recent versions. In this case, you may need to install a newer version of tar from a different source.
