.bash_history Timestamp Discrepency

The .bash_history file, located within a user's directory on MacOS and Linux, is written with command history from shell sessions.

If the file has a Created timestamp, but a user has used a shell utility previously, this may indicate the file was deleted and manually or automatically re-created.

Sections

ID	Name	Description
AF001	Clear Command History	A subject clears command history to prevent executed commands from being reviewed, disclosing information about the subject’s activities.
AF001.002	Clear Bash History	A subject clears bash terminal command history to prevent executed commands from being reviewed, disclosing information about the subject’s activities. The Command Prompt on Windows only stores command history within the current session, once Command Prompt is closed, the history is lost. On Linux-based operating systems different terminal software may store command history in various locations, with the most common being `/home/%username%/.bash_history`. Using the command `history -c` will clear the history for the current session, preventing it from being written to `.bash_history` when the session ends. On MacOS the Terminal utility will write command history to `/Users/%username%/.zsh_history` or `/Users/%username%/.bash_history` based on operating system version.
