Awesome git addons

Awesome git addons is yet another one of those curated awesome lists. This time it’s for git version control tool. And once again, it’s mind blowing.

Git itself is a very flexible and powerful tool. But it truly amazing how far some people take it. In the list you can find anything from aliases for complex commands, to full-featured integrations with GitHub, git flow process, deployment tools, and much more.

CurlMail – easy way to send emails with cUrl

I am a big fan of small and simple yet practically interesting ideas, like this one. CurlMail is a super easy API service that allows one to send emails from the command line, using nothing but curl, or a similar HTTP client.

It’d be extra cool if it there was a GitHub link to it too. But even if it’s not openly available, one could use the service for emails which are not sensitive and implement something similar from scratch in a few minutes for private use.

Archiving web sites

LWN runs an interesting article, covering different ways of archiving a website. It sounds trivial, but it’s not. Even the simplest of ways – wget – will probably take you a few dozen attempts to figure out the following:

$ wget --mirror --execute robots=off --no-verbose --convert-links \
       --backup-converted --page-requisites --adjust-extension \
       --base=./ --directory-prefix=./ --span-hosts \
       --domains=www.example.com,example.com http://www.example.com/

There a few other interesting tools (like pywb) mentioned.

percollate – a command-line tool to turn web pages into beautifully formatted PDFs

percollate is a command-line tool to convert web pages into PDF files. It supports single-page and multi-page files, can fetch the HTML documents from the web, understands accelerated mobile pages (see AMP), and even allows some control of the output with CSS snippets.

Using aws-cli –query Option To Simplify Output

Eric Hammond shares a super-handy tip for those of us who work with Amazon AWS via the command line:

I just learned about a recent addition to aws-cli: The --query option lets you specify what parts of the response data structure you want output.

Instead of wading through pages of JSON output, you can select a few specific values and output them as JSON, table, or simple text. The new --query option is far easier to use than jq, grep+cut, or Perl, my other fallback tools for parsing the output.
