xxcmd 0.2.0

A helper for remembering useful shell commands.

xxcmd

xx is a Linux shell command. xx remembers other shell commands, so you don't have to.

Installation

Requires Python 3. Easy install through pip.

On Ubuntu:

sudo pip3 install xxcmd

On Arch:

sudo pip install xxcmd

Basic Usage Examples

Using xx is pretty simple. You build up a database of useful commands, and search and execute them whenever you like.

Adding Commands

Commands are added to the database with:

xx -a [label] <command>

Add a very simple command top. Not very useful as the command is already short and easy to remember.

xx -a top

Add the du command to display size of all files and directories in the current directory.

xx -a du --max-depth=1 -h .

Add the same command but with a friendly (searchable) label:

xx -a [File Size] du --max-depth=1 -h .

Adding our favourite ssh command:

xx -a [SSH Best Host] ssh -i ~/.ssh/mykey.pem [e-mail]

Browse and Search Commands Interactively

Run xx with no options to enter the interactive UI.

xx

Fast search and execute

xx can search for matching commands and if only one match is found it will be immediately executed. To run the command we just added we could search for "du":

xx du

Or to run it by searching for a partial match of the label we added:

xx size

We could immediately ssh connect with:

xx best

Interactive UI

Invoking xx without options will open the interactive UI. Presenting a list of all commands with an interactive search.

Keys:

• UP/DOWN arrow keys - navigate the list of commands.
• DELETE - remove the currently selected command
• RETURN - execute the currently selected command
• ESCAPE - exit
• Any other key press is added to the interactive search to filter the command list.
