I can't think of any. What good is a history that doesn't include all the commands that have been used? Well, complex commands. I've turned off some common commands, like ls, because all they are is clutter. I also turned off saving duplicate commands, though that only works if they are contiguous in history. I think that would be a downside to this if people weren't used to all the clutter in their history. Though, with Ctrl-R, it really doesn't matter. I actually wrote a little python program to load history, and eliminate all duplicate commands in history while preserving order of the commands. So, the last duplicate command is always the one saved. > > Any thoughts? I have the following defined in .bashrc: # this logs the history explicitly before exiting a shell hx () { history -a; exit; } It means that I have to exit using the command hx when closing a terminal. Not as elegant as an automatic process you are suggesting, but it seems to work. I'll have to try the process you are suggesting, (from the link you gave), to see if it results in the same effect. _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
