README

ccat

cat on steroids. Leveraging great go modules to ease my CLI life.

install

• get the latest release from https://github.com/batmac/ccat/releases/latest
• or go install github.com/batmac/ccat/cmd/ccat@latest

then, you can update to the latest github release with ccat --selfupdate

build

you need a recent go, available build tags:

• libcurl: build with the libcurl opener.
• fileonly: build with the local file opener only.
• nohl: build without the syntax-highlighter.
• crappy: build with some crappy (but useful) openers/mutators (needs a recent go version).

for instance: go build --tags libcurl,crappy .

examples

cat -X "kubectl get all" -i -w -t ready,Running --bg
NAME           READY   STATUS    RESTARTS   AGE

docker image

multi-arch container images with tags libcurl,crappy are automatically built by Github Actions and made available on Dockerhub and Github Packages.
for instance:

docker run --rm ghcr.io/batmac/ccat:latest -h

or

kubectl run -i --tty ccat --image=batmac/ccat:latest -- /bin/sh
