createrepo: Initialize a repository, using SHA1 as the checksum algorithm, and ignoring symbolic links.

createrepo

$ createrepo -S -s ${sha1} ${path-to-directory}

try on your machine

The command createrepo is used to create a metadata repository for a directory containing RPM package files. It generates the necessary metadata files that tools like yum use to locate, download, and install packages.

Here is the breakdown of the command:

createrepo: The command itself that initiates the creation of the repository.
-S: It tells createrepo to generate the filelists.xml.gz file. This file contains a list of all the files in the repository.
-s ${sha1}: It specifies the checksum type to be used for the metadata files. The ${sha1} here is a placeholder for the SHA1 checksum algorithm. You can replace it with another supported algorithm like ${md5} if desired.
${path-to-directory}: This is the path to the directory where the RPM package files are located. It should be replaced with the actual path to your desired directory.

To summarize, the command createrepo -S -s ${sha1} ${path-to-directory} creates a repository metadata in the specified directory using the SHA1 checksum algorithm.
