keyctl:tldr:ced53

The command keyctl timeout ${key_name} ${timeout_in_seconds} is used to set a timeout value for a key in a Linux kernel keyring.

Explanation of command components:

• keyctl: It is a command-line utility in Linux used for managing keys and keyrings.
• timeout: It is a subcommand of keyctl used to set a timeout value for a key.
• ${key_name}: This is the name of the key for which the timeout is being set. It is a placeholder for the actual key name.
• ${timeout_in_seconds}: This specifies the timeout duration for the key in seconds. It is a placeholder for the actual timeout value to be set.

In summary, the command sets a timeout for a specific key in the Linux kernel keyring, where ${key_name} represents the name of the key, and ${timeout_in_seconds} sets the timeout duration for that key in seconds.
