cURL - クライアントサイドURL転送ライブラリ

明治製菓 カール チーズ味 001
※日本では明治製菓の「おやつはカール」がイメージです❓😅💦💦💦 チーズ味最高です💕

cURL (カール) は、さまざまなプロトコルを用いてデータを転送するライブラリとコマンドラインツールを提供するプロジェクトである。cURL プロジェクトは libcurl と curl の2つの成果を生んでいる。

本家: curl
ソースコード: curl/curl: A command line tool and library for transferring data with URL syntax, supporting HTTP, HTTPS, FTP, FTPS, GOPHER, TFTP, SCP, SFTP, SMB, TELNET, DICT, LDAP, LDAPS, MQTT, FILE, IMAP, SMTP, POP3, RTSP and RTMP. libcurl offers a myriad of powerful features

TODO: 詳細は必要に応じて追記していきます😅💦💦💦

インストール

Fedora では既にインストール済みである🤔

$ sudo dnf install curl


メタデータの期限切れの最終確認: 3:30:08 時間前の 2022年09月21日 03時52分59秒 に実施しました。
パッケージ curl-7.82.0-8.fc36.x86_64 は既にインストールされています。
依存関係が解決しました。
行うべきことはありません。
完了しました!

SourceForge.net を curl で取得する方法

SourceForge.net にあるプロジェクトである Open JTalk download | SourceForge.net のファイルを入手したくて自分なりにいろいろと試してみた結果をまとめておくことにする。
SourceForge.net 公式の文献として存在しているかは未確認であるため、SourceForge.net の仕様が変わるとこの方法は通用しなくなるかもしれませんのでご了承ください。

例えば、以下のファイルをダウンロードしたいとする。
https://sourceforge.net/projects/open-jtalk/files/Open%20JTalk/open_jtalk-1.11/open_jtalk-1.11.tar.gz
ブラウザーでは上記のような階層 (open-jtalk プロジェクトの /Open JTalk/open_jtalk-1.11/open_jtalk-1.11.tar.gz) であるが、2020/09/13 現在 も確認したところ curl コマンドではディレクトリ階層を無視して、以下の形式の URL の指定でダウンロードすることが可能である。

$ curl -LO https://downloads.sourceforge.net/open-jtalk/open_jtalk-1.11.tar.gz

https://downloads.sourceforge.net/{Project Name}/{File Name}

SourceForge.net のシステムは優秀ですね😊

最終リリースのものをダウンロードしたい場合は以下のように記述することもできる。

$ curl -LO https://sourceforge.net/projects/open-jtalk/files/latest

何が起きていて失敗しているかわからないときの [-I, --head / -v, --verbose]
