The pipeline shell command

A utility to make building up a pipeline of shell commands easier, especially when doing data exploration.

If you've ever found yourself writing shell code, in an endless loop of piping output to less, scanning it over and making changes, then pipeline can make your life just a little bit more beautiful.

This is just a thin wrapper around your shell, not some totally new data mining tool. Launch pipeline, and start typing shell commands as usual. Every time you hit enter you'll see a one-screen preview of your output, similar to piping output to less, but your cursor will stay right where it was for further editing.

Ctrl-C when you're done, to exit.

Installation

Pipeline depends only on ncurses and readline (or libedit), both of which ship with MacOS and most common Linux distros.

MacOS

Install with Homebrew.

brew tap codekitchen/pipeline
brew install pipeline

From Source

You can download the latest release tarball from the releases page, or git clone the repo to build the master branch.

# only run this command if building from git, skip this if using the tarballs from release page
autoreconf -fi

./configure

make

After make finishes, you'll be able to use ./pipeline. You can also install it using:

sudo make install

Windows

It might work under MinGW/GitBash? Please let me know.

Docker Container

The commands below will assist in the following;

• Get a dockerfile, from this repository.
• Build a lightweight docker image with the powerline shell command.
• Add an alias that will enable you to call the powerline docker image as a container.
• The Docker container will automatically mount the directory path you are at.
• It will also spawn the powerline shell command, so you won't feel as if you are in a container.

You will exit the docker container, when exiting the powerline shell command, the docker container will be removed after exiting the container.

# Get the dockerfile2 file
curl -L https://raw.githubusercontent.com/iAmG-r00t/pipeline/master/Dockerfile2 -o pipeline-dockerfile

# Build a powerline image
docker build -t pipeline:latest -f pipeline-dockerfile .

# Alias
alias pipeline='docker run -it --rm --name pipeline -v `pwd`:/root pipeline:latest' 

Note: Docker has to be already installed.
