I'm using HISTIGNORE to ignore the most used commands and HISTCONTROL=ignoreboth:erasedups to remove duplicates.



Is there a way to periodically sort the contents of the .bash_history in alphabetical order?






bash cron

  • Please define ”periodically”, and where would you like to store the output; once sorted.

  1. To see a sorted history without changing it, do:



    history | sort -k2



  2. To sort the history file, do:



    sort -o ~/.bash_history ~/.bash_history


    Then log out of bash by typing exit, and log back in. The new
    terminal instance will have an alphabetically sorted history.




  3. For the most cautious possible way to sort the history file, first exit all
    running instances of bash, (for the current user anyway), then do:



    sort -o ~/.bash_history ~/.bash_history


    Note: Users generally have no bad results from editing ~/.bash_history while still logged in. But it's fairly certain that exiting all running instance of bash is as safe or safer.

  • This answer would be better with a cron job method as well, but I'm undecided on how to handle systems where terminals are left open for long periods of time. Maybe the job could remind them to log out and log back in, but suppose that's not convenient. Better still would be to have a method that doesn't require and exit at all.
