ASDF2

Fast history searching tool for bash.

Rewrite of this script using ncurses for blazing fast speed, hence the 2.

Using asdf to search for a command and running it:

Building

Requirements:

  • ncurses development headers/libraries (you need to do something like sudo apt-get install ncurses-dev on Ubuntu, or brew install ncurses on Mac, or install the libncurses-devel package on Windows/Cygwin)

  • bash 4 (Mac install instructions)

  • make

You should be able to just run make, and it should build fine assuming you have ncurses installed.

Running

After you've built it simply run ./asdf. You can add it to your PATH to be able to use it from anywhere. Certain bash commands (like cd some/path) won't run correctly because this will be inside of a subshell, which then exits, losing your changes. In order to get around that you can source asdf instead of just running it. Simply add alias asdf="source /path/to/asdf" to your .bashrc.

Controls:

  • <Up>/<Down> -> select different commands

  • <Enter> -> runs the selected command

  • <C-Space> -> edit the selected command before running it

  • <C-Del> (or <C-\> on Mac) -> remove the selected command (and any copies) from your HISTFILE

Extras

Not required, but adding the following to your .bashrc can make interacting with your history a little bit nicer:

# make history virtually unlimited
export HISTSIZE=1000000
export HISTFILESIZE=$HISTSIZE

# make it so that asdf doesn't show up in the history
export HISTIGNORE="$HISTIGNORE:asdf*"

# append commands to the history as they're run (instead of after the shell exits)
shopt -s histappend
PROMPT_COMMAND="history -a;$PROMPT_COMMAND"

TODO:

  • Clean up the code. It's kind of a mess right now. Manageable, but a mess.

  • Add support for other shells (zsh and fish at least)

  • Add support for bash movement hotkeys (like ^W deleting a word)

  • Add regex support (assuming it doesn't slow things down too much)
