The command "keychain --timeout ${minutes}" is used to manage SSH and GPG keys in an agent.
Here is a breakdown of the command:
-
"keychain": This is the name of the command-line utility used to manage keys within an agent. Keychain helps to automatically load and manage SSH and GPG keys in a secure way.
-
"--timeout ${minutes}": This is an option passed to the "keychain" command. The "--timeout" flag specifies the duration after which the SSH or GPG key loaded in the agent should be automatically removed. "${minutes}" represents the value of minutes that is passed as a parameter. For example, if "${minutes}" is set to 10, it means that the key will be removed from the agent automatically after 10 minutes of inactivity.
In summary, this command sets a timeout period for SSH or GPG keys loaded in the agent managed by Keychain. After the specified time of inactivity, the key will be removed from the agent automatically.
