You can make your shell history more useful by removing the typos and false starts.

    I comment the commands that I want and then use vim to remove ones without comments.

    For example, I run:

    longandannoyingcommand -f1 -f2 -f3 # keep, does something useful

    Usually comment explains what the command does so I can find it by description using fzf history search. And then you can easily find all lines that contain (or do not contain “# keep”) in your history to remove or keep.

      We are same. I sometimes use comments as kind of tags, like

      xinput --disable $(xinput --list | grep -i touchpad | grep 'id=[0-9]\+' -o | cut -d= -f2)  # Disable synaptic touchpad trackpad pointer

      or

      python3 -c 'from ctypes import *; X11 = cdll.LoadLibrary("libX11.so.6"); X11.XOpenDisplay.restype = POINTER(c_ubyte); display = X11.XOpenDisplay(None); X11.XkbLockModifiers(display, c_uint(0x0100), c_uint(2), c_uint(0)); X11.XCloseDisplay(display)' # swap caps CAPS CAPSLOCK

      or sometimes I’ll add # works at the end of a long string of attempts (usually involving dialing into a regexp), like

      xdpyinfo|grep dimensions|grep -Eow '\d'
xdpyinfo|grep dimensions|grep -Eow '(\d)'
xdpyinfo|grep dimensions|grep -ow '(\d)'
xdpyinfo|grep dimensions|grep -o '(\d)'
xdpyinfo|grep dimensions
xdpyinfo|grep dimensions|grep '1920x1080'
xdpyinfo|grep dimensions|grep -o '1920x1080'
xdpyinfo|grep dimensions|grep -o '\d920x1080'
xdpyinfo|grep dimensions|grep -Po '\d920x1080'
xdpyinfo|grep dimensions|grep -Po '\d+x1080'
xdpyinfo|grep dimensions|grep -Po '\d+x\d+'
xdpyinfo|grep dimensions|grep -Po '(\d+x\d+)'
xdpyinfo|grep dimensions|grep -Po '(\d+x\d+) pixels'
xdpyinfo|grep dimensions|grep -Po '(\d+x\d+) pixels'|cut
xdpyinfo|grep dimensions|grep -Po '(\d+x\d+) pixels'|cut -f1
xdpyinfo|grep dimensions|grep -Po '(\d+x\d+) pixels'|cut -d\ -f1
xdpyinfo|grep dimensions|grep -Po '(\d+x\d+) pixels'|cut -d'' -f1

    Atuin (by @ellie@hachyderm.io) makes the history storage and management side much easier and portable, but could perhaps use a “smite mode” to make deletion interactively easier. The current interactive implementation prioritizes safety over expediency which is fine, but a “today I clean things” option could perhaps instead prioritize the other way around and enable one key delete w/ undo instead.

    I might try this. Normally would just pipe history into grep to search or scroll till I found the right command. Also smite is a great name for that function.
