包 [zfsnap] 安装不正确 - 是什么？

在 Ubuntu Xenial 服务器上，安装时zfsnap出现错误状态0。但是，软件包未正确安装：

$ zfsnap
zfsnap: command not found
$
$ sudo dpkg -p zfsnap
dpkg-query: package 'zfsnap' is not available
Use dpkg --info (= dpkg-deb --info) to examine archive files,
and dpkg --contents (= dpkg-deb --contents) to list their contents.
$
$ sudo dpkg -s zfsnap
Package: zfsnap
Status: install ok installed
Priority: extra
Section: admin
Installed-Size: 80
Maintainer: Ubuntu Developers <[email protected]>

Depends: zfs-fuse | zfsutils | zfs, bc

这里有什么内容（或我应该看看的其他内容）可以表明为什么该软件包不能正常工作吗？

以下是apt安装的输出：

$ sudo apt install zfsnap

答案1

您可以使用以下命令查看软件包中包含的文件列表

dpkg-query -L zfsnap

要查看可用的命令，在本例中你可以搜索 /usr/bin 或 /usr/sbin：

dpkg-query -L zfsnap|grep /usr/sbin

编辑：用花哨的正则表达式捕获所有内容;）

dpkg-query -L zfsnap|egrep "(/usr)*/(s*)bin"

答案2

»» $ zfsnap
zfsnap: command not found ««

zfsnap 软件包提供/usr/sbin/zfSnap：请注意大写年代在赞吧。

拼写，1）阅读文件列表dpkg -L zfsnap 2）在线阅读http://packages.ubuntu.com/xenial/all/zfsnap/filelist
