was reading "man bash" and ran across this:
"When an interactive login shell exits, or a non-interactive login shell executes the exit builtin command, bash reads and executes commands from the files ~/.bash_logout and /etc/bash.bash_logout, if the files exists."
i was totally unaware of the system-wide logout file /etc/bash.bash_logout, so i tested it and it seemed to have no effect, so i RTFS for bash and, in the CHANGES file, there was this from way back:
"This document details the changes between this version, bash-2.0-beta2, and the previous version, bash-2.0-beta1.
... snip ...
There is a new #define available in config.h.top: SYS_BASH_LOGOUT. If defined to a filename, bash reads and executes commands from that file when a login shell exits. It's commented out by default."
sure enough, in the current source in that file:
/* System-wide .bashrc file for interactive shells. */ /* #define SYS_BASHRC "/etc/bash.bashrc" */
/* System-wide .bash_logout for login shells. */ /* #define SYS_BASH_LOGOUT "/etc/bash.bash_logout" */
so if red hat builds bash based on the source as it is, then that variable is still commented out and the man page is misleading. thoughts?

Both ~/.bash_logout and /etc/bash.bash_logout are honored on my F27 system.

Probably you were testing with a shell that wasn't a login shell.
