A python tool connected to your terminal to store important commands and search them in a new and faster way

Search sample

Why you need it?

How often do you need to reuse a command but you cannot remember it (or all the needed options/flags)?

# example of an 'intuitive' and 'obvious' bash command from my bash history
$ srm -lrvz f1 f2 d1/

How many times do you search the same command on Google, over and over?

42 times.. yes.. based on my experience the answer is 42

And how many times have you told yourself to store this super useful command but you didn't?

I saved them all ..totally, with a good and detailed explanation for each command

if you know what I am talking about, fastHistory is the tool you are looking for!

The tool

fastHistory can save your commands directly from your terminal, all you need is a #

$ srm -lrvz f1 f2 d1/ #
                      \------- fastHistory will store "srm -lrvz f1 f2 d1/" in its internal database

You can specify one or more tags

$ srm -lrvz f1 f2 d1/ #secure #remove #file #directory

or a description

$ srm -lrvz f1 f2 d1/ #@delete file and overwrite it 2 times

or both

$ srm -lrvz f1 f2 d1/ #secure #remove #file #directory @delete file and overwrite it 2 times

Finally, to search your saved commands, all you need is f

$ f secure

fastHistory will then inject the selected command in your terminal input

Search sample

Furthermore, for each saved command you can get a fast summary from the man page with details of the used options/flags Warning: this feature currently does not cover the syntax of all commands

Info ls sample

How to install

Warning: this tool is still under development! A first version will be soon released

  1. enable fastHistory in your terminal
echo 'source "$HOME/fastHistory/bash/f.sh"' >> .bashrc
