This command is related to managing security certificates on a macOS system using the security command-line tool.

Here's a breakdown of the command components:

• security: It is a command-line tool on macOS used to manage various security services, including certificates.
• add-certificates: This subcommand is used to add one or more certificates to a keychain.
• -k ${file-keychain}: The -k option is followed by the keychain file path (${file-keychain}). A keychain is a secure container that stores cryptographic keys, certificates, and other sensitive data. This option specifies the keychain where the certificate(s) will be added.
• ${path-to-cert_file-pem}: This represents the path to the certificate file in the PEM format. The PEM format is a commonly used file format for storing certificates and private keys.

In summary, the command is used to add one or more certificates from a PEM file to a specified keychain on a macOS system.
