Store, search and automatically paste all your favourite commands directly in your terminal with a new and faster way!

With the new TDLR-pages integration, you can quickly discover and select more than 10000 ready-to-use command examples, directly in your terminal.

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

# example of a common but not so 'easy-to-remember' bash command from my bash history
$ tar -xvzf file.tar.gz

How many times do you search the same commands 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!

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

$ tar -xvzf file.tar.gz #
                       /\
                        \-- fastHistory will store 'tar -xvzf file.tar.gz' in its local database

You can specify one or more tags

$ tar -xvzf file.tar.gz #untar #extract #archive 

or a description

$ tar -xvzf file.tar.gz #@extract compressed files from archive

or both

$ tar -xvf archive.tar.gz #untar @extract compressed files from archive

To search the saved commands, all you need is f and the selected command wiil be automatically pasted into your terminal!

$ f

For each stored command you can get a quick summary from the man page

note: this feature does not cover the syntax of all commands

And easily edit the tag and description fields

Furthermore, you can easily export/import all data to make backups or to share your commands with a different machine

$ f --export
$ f --import fastHistory_2020-03-02.db

In the Discovery mode, you can easily find examples of commands from the TDLR-pages, a collection of community-maintained help pages. The search works both by command name and description. Furthermore, the icon shows you which command is already installed on your system.

FastHistory does not need any internet connection, so you can use it also offline!

fastHistory can work in any OS with python3 and a bash terminal

zsh is also supported!
