Sorry, I am not expert in this field. The discussion just caught my attention and that was result of my very brief research.
With that caveat, it seems that a .bash_logout only executes on login shells. So, it would not save the history of terminals in X when they were closed. Am I misunderstanding? I did find something that might work in that case, at this link. https://superuser.com/questions/410525/explain-why-bash-logout-wont-run-commands/410534#410534 """ ~/.bash_logout is only run if it you explicitly exit the shell with exit or logout, or by typing Control-D to enter an end-of-file at the command prompt. If you close the terminal emulator, processes are sent SIGHUP, and bash doesn’t run ~/.bash_logout in that case. If you want to perform work any time bash exits (and whether it’s a login shell or not), use trap foo EXIT. The most convenient way to do this is to put your code in a shell function, e.g.,: print_goodbye () { echo Goodbye; } trap print_goodbye EXIT """
Interesting. Thx for the link.
Typing exit or logout is more keystrokes than hx, so .bash_logout is not really compelling.
Ctrl+D is what I am using all the time. That is probably less keystrokes then `hx`, because you save the pressing the Enter ;)
Vít
The trap looks promising, I assume that I would put
save_history_on_exit () {history -a;}
trap save_history_on_exit EXIT
in .bashrc. Basically, running a .bash_logout in a different way.
Thanks.
