What script is typically executed when a user logs out of a shell session?

When a user logs out of a shell session, the script that is typically executed is the one located at ~/.bash_logout. This file is specifically designed for Bash shell users to define commands or scripts that they want to be executed automatically upon exiting their shell session. This could include tasks like cleaning up temporary files or saving session data.

The reason this specific file is invoked during logout is that the Bash shell looks for specific configuration files that correspond to various shell events. The .bash_logout file is one of these, tailored for actions that should occur when a user logs out.

Other options have different purposes: ~/.bash_profile is used for commands that should be run at the start of a login shell session, typically for setup tasks like environment variable configuration. Similarly, ~/.logout is not a standard file tied to the Bash shell, but rather a general convention used in some other shells for logout actions. Lastly, ~/.bash_exit is not a recognized script associated with Bash logout events, making it irrelevant in this context.
