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.

How many registers does an x86_64 CPU actually have?

Image
Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
