如何获取 snap 包的版本号？

如果我想使用 apt 安装 VLC，我可以运行

apt-cache show vlc | grep -i version
Version: 2.2.4-14ubuntu2

这将告诉我 apt 将引入的版本。Snap 当前在其存储库中有 VLC 3.x。但是，如果不将其拉下来并安装，我该如何查看它？

snap info理论上是你想要的。但是，开发者需要告诉商店他们上传了哪个版本。vlc 开发者还没有这样做：-

alan@gort:~$ snap info vlc
name:      vlc
summary:   "The ultimate media player"
publisher: videolan
contact:   https://www.videolan.org/support/
description: |
  VLC is the VideoLAN project's media player. It plays MPEG, MPEG-2, MPEG-4,
  DivX, MOV, WMV, QuickTime, WebM, FLAC, MP3, Ogg/Vorbis files, DVDs, VCDs,
  podcasts, and multimedia streams from various network sources.

channels:              
  stable:    daily (4) 120MB -
  candidate: daily (4) 120MB -
  beta:      daily (4) 120MB -
  edge:      daily (4) 120MB -

然而，开发人员还有其他快照，例如：-

alan@gort:~$ snap info atom
name:      atom
summary:   "A hackable text editor for the 21st Century."
publisher: flexiondotorg
contact:   [email protected]
description: |
  Atom is a free and open source text editor that is modern,
  approachable, and hackable to the core.

commands:
  - atom
tracking:    edge
installed:   1.16.0 (2) 150MB classic
refreshed:   2017-04-21 16:35:56 +0100 BST
channels:               
  stable:    1.16.0 (2) 150MB classic
  candidate: 1.16.0 (2) 150MB classic
  beta:      1.16.0 (2) 150MB classic
  edge:      1.16.0 (2) 150MB classic

我认为这是上游软件包中的一个错误，开发人员应该解决它。

怎么样snap list：

列出所有软件包并 grep 那里显示的版本

$snap list
Name     Version   Rev    Tracking       Publisher     Notes
core18   20210722  2128   latest/stable  canonical✓    base
snapd    2.51.4    12883  latest/stable  canonical✓    snapd

用于grep特定包：

snap list | grep vlc
