apt-缓存显示未来命令

Question

一旦通过apt-get安装了软件包，有什么方法可以找到哪些命令可用？

假设我想运行apt-get -y net-tools。

Description-en: The NET-3 networking toolkit
 This package includes the important tools for controlling the network
 subsystem of the Linux kernel.  This includes arp, ifconfig, netstat,
 rarp, nameif and route.  Additionally, this package contains utilities
 relating to particular network hardware types (plipconfig, slattach,
 mii-tool) and advanced aspects of IP configuration (iptunnel, ipmaddr).
 .
 In the upstream package 'hostname' and friends are included. Those are
 not installed by this package, since there is a special "hostname*.deb".

apt-cache show net-tools是否已经公开了所有的内容(arp，ifconfig，netstat，rarp，nameif，route，plipconfig，sl附件，mii-tool，ip隧道，ipmaddr)？

Answer 1

apt-cache没有办法做到这一点。然而，apt-file会按你的要求去做。手册：http://manpages.ubuntu.com/manpages/vivid/en/man1/apt-file.1.html

您可以运行apt-file list net-tools来列出由net安装的文件，即使没有安装net.

apt-file确实对此信息使用了缓存，您需要使用apt-file update定期更新这些信息。

Answer 2

即使还没有下载，也可以使用apt-file列出包中的所有文件。然后通过grep过滤它。

$ apt-file list net-tools | grep bin
net-tools: /bin/netstat
net-tools: /sbin/ifconfig
net-tools: /sbin/ipmaddr
net-tools: /sbin/iptunnel
net-tools: /sbin/mii-tool
net-tools: /sbin/nameif
net-tools: /sbin/plipconfig
net-tools: /sbin/rarp
net-tools: /sbin/route
net-tools: /sbin/slattach
net-tools: /usr/sbin/arp
