我有兴趣将 torrent 文件渲染为可读形式（查看它引用了哪些文件，它包含哪些跟踪器信息等）。我可以使用什么工具来做到这一点？

您可以使用transmission-show, 包含在Gnome Transmission BitTorrent 客户端。
$ transmission-show amd64cd-5.1.2.iso.torrent
Name: amd64cd-5.1.2.iso
File: amd64cd-5.1.2.iso.torrent

如果您使用的是旧版本传播，您可以使用旧transmissioncli --info命令：
$ transmissioncli --info amd64cd-5.1.2.iso.torrent

答案2
您可以使用aria2。从aria2c(1) 手册页:
-S, --show-files[=true|false]打印“.torrent”、“.meta4”和“.metalink”文件的文件列表并退出。如果是“.torrent”文件，还会打印附加信息（infohash、片段长度等）。
$ aria2c -S ubuntu-14.04.2-desktop-i386.iso.torrent >>> 打印文件“ubuntu-14.04.2-desktop-i386.iso.torrent”的内容... *** BitTorrent 文件信息 *** 评论：Ubuntu CDreleases.ubuntu.com 创建日期：2015 年 2 月 19 日星期四 22:17:32 GMT 模式：单人 宣布： http://torrent.ubuntu.com:6969/announce http://ipv6.torrent.ubuntu.com:6969/announce 信息哈希：33678ec8b0dfb8a9061348c8af7194268c0b8310 片长：512KiB 件数：2006年 总长度：0.9GiB (1,051,721,728) 名称：ubuntu-14.04.2-desktop-i386.iso 磁铁 URI：magnet:?xt=urn:btih:33678EC8B0DFB8A9061348C8AF7194268C0B8310&dn=ubuntu-14.04.2-desktop-i386.iso&tr=http%3A%2F%2Ftorrent.ubuntu.com%3A6969%2Fannounce&tr=http%3A%2 F%2Fipv6。 torrent.ubuntu.com%3A6969%2Fannounce 文件： idx|路径/长度 ================================================== ============================= 1|./ubuntu-14.04.2-desktop-i386.iso |0.9GiB (1,051,721,728) ---+-------------------------------------------------------- ----------------------------

btshowmetainfo以前包含在 BitTorrent 发行版中，但现在主要随 BitTornado（BitTorrent 3.x 代码库的一个分支）一起安装，它就是这样做的。
$ btshowmetainfo amd64cd-5.1.2.iso.torrent
btshowmetainfo 20030621 - decode BitTorrent metainfo files

您可以使用torrenttools。
torrenttools info test.torrent
Metafile: /home/fbdtemme/Downloads/Fedora-Workstation-Live-x86_64-33.torrent
Protocol version: v1
Infohash: 7707056a138a00dd9b9eff4fab29f46233e2bad9

您还可以仅检索在 shell 脚本中有用的特定字段。
torrenttools show infohash test.torrent
17ebe3685a498afcc06e2241e875a1726e7c38c2
torrenttools show announce Fedora-Workstation-Live-x86_64-33.torrent
http://torrent.fedoraproject.org:6969/announce
查看 json 格式的解码 torrent 文件会很有用。
torrenttools info --raw Fedora-Workstation-Live-x86_64-33.torrent
{

],

}
您可以使用 --show-pieces 选项扩展pieces字段。
torrenttools info --raw --show-pieces Fedora-Workstation-Live-x86_64-33.torrent

...
torrenttools 还可以使用新的 BitTorrent v2 图元文件和混合 torrent。
torrenttools info bittorrent-v2-hybrid-test.torrent
Metafile: /home/fbdtemme/Documents/project/torrent/torrenttools/tests/resources/bittorrent-v2-hybrid-test.torrent
