時々、基本的なHTMLをコンソールに出力する簡単なタスクを実行する必要があります。一目で読みやすくするために、最小限のレンダリングで済ませたいと思います。シェルで基本的なHTMLレンダリングを処理できるユーティリティはありますか( Lynx -styleレンダリング-とはいえ、実際のブラウザでは考えられません)?
たとえば、Apacheのmod_status
ページにwatch
を配置することがあります。
watch -n 1 curl http://some-server/server-status
ページの出力は、最小限のマークアップを含むHTMLであり、シェルには次のように表示されます。
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">
<html><head>
<title>Apache Status</title>
</head><body>

Lynxで表示すると、同じHTMLが次のようにレンダリングされます。ApacheStatus(p1 of 2)Apache Server Status for localhost

lynx
には「ダンプ」モードがあり、watch
で使用できます。
$ watch lynx https://www.google.com -dump
から man lynx
:
-dump dumps the formatted output of the default document or those
specified on the command line to standard output. Unlike
interactive mode, all documents are processed. This can be used
in the following way:
lynx -dump http://www.subir.com/lynx.html
Files specified on the command line are formatted as HTML if
their names end with one of the standard web suffixes such as
“.htm” or “.html”. Use the -force_html option to format files
whose names do not follow this convention.
この buntuの質問 には、さらに多くのオプションがあります。
w3m
は、--dump
オプション。
これは、バックエンドのEmacsで最も人気のあるWebブラウザーです。
elinks
には-dump
モードも
elinks -dump https://www.google.com
