compare two wikis for installed extensions and skins
Sometimes one-liners are so cool, you just want to remember them. And good one-liners can also teach you the intricacies and features of the [[Bash]] shell. Although there are better sites on the Internet for [http://www.bashoneliners.com/ finding one-liners], [http://www.catonmat.net/series/bash-one-liners-explained understanding one-liners] or [http://uni.xkcd.com/ playing on the command line], we'd still like to illustrate a few here.
== Compare two wikis for extensions and skins ==
This one-liner invokes the API of two wikis asking for info on siteinfo, general, extensions and skins; in json format. Since that data is returned without any newlines, we use `jq` to pretty-print the json output. Then it's an easy `meld` or `diff` to compare them. The `--silent` option to `curl` just suppresses the connection and retrieval metadata; while the `-L` is customary to follow redirects.
