阅读未安装程序帮助的最快方法（我很幸运）

  • 772

查找当前未安装程序信息的最快方法是什么？

今天我需要 Ubuntu 来提醒我一些事件，我认为 Ubuntu 可以像 Google 的I'm Feeling Lucky按钮一样智能。但不幸的是，这没有用：

$ remind
The program 'remind' is currently not installed. You can install it by typing:
sudo apt-get install remind
$ man remind
No manual entry for remind
$ help remind
bash: help: no help topics match `remind'.  Try `help help' or `man -k remind'
or `info remind'.

在安装之前，我希望检查提醒是否真的是我需要的。

当然info remind没有帮助（根本不需要展示）。man -k工具也没有帮助：

$ man -k remind
calendar (1)         - reminder service

并且挖掘它man -k的含义也没有成功：

-k, --apropos              equivalent to apropos

那么，您如何从命令行找到所需的应用程序呢？

command-line

    还有dman来自bikeshed包。

    sudo apt-get install bikeshed

    它可以让你从互联网上阅读手册页，而不需要安装相应的包：

    dman remind

    1. 阅读联机手册页。

    2. 使用apt-cache

      apt-cache show remind

      或者

      apt-cache show remind | awk '/Description-en/ {print; a=1; next} a && /^ / {print; next} {a=0}'

    3. 其他一切都包含在包本身中。

      apt-get download remind
dpkg -x *.deb remind
man ./remind/usr/share/man/man1/rem.1.gz

    示例输出

    apt-cache show remind
