1 tldr 介绍

今天发现了一个好玩的命令，该命令会根据二八原则给出命令的常用场景示例，支持在近20种语言环境下运行，通过tldr --update更新本地命令库。什么--help和man都弱爆了。兴奋的我不行不行的，与大家分享一下，把节省的时间去聊妹子吧

官网介绍:https://github.com/tldr-pages/tldr

 

2 tldr命令安装

安装官网提示安装即可，那我选择简单的安装方式

# npm install -g tldr
/home/xiaoxu/node-v10.9.0-linux-x64/bin/tldr -> /home/xiaoxu/node-v10.9.0-linux-x64/lib/node_modules/tldr/bin/tldr
+ tldr@3.2.7
added 113 packages from 103 contributors in 16.052s

3 使用该命令

# tldr tar

  tar

  Archiving utility.
  Often combined with a compression method, such as gzip or bzip.

  - Create an archive from files:
    tar -cf target.tar file1 file2 file3

  - Create a gzipped archive:
    tar -czf target.tar.gz file1 file2 file3

  - Extract an archive in a target directory:
    tar -xf source.tar -C directory

  - Extract a gzipped archive in the current directory:
    tar -xzf source.tar.gz

  - Extract a bzipped archive in the current directory:
    tar -xjf source.tar.bz2

  - Create a compressed archive, using archive suffix to determine the compression program:
    tar -caf target.tar.xz file1 file2 file3

  - List the contents of a tar file:
    tar -tvf source.tar

  - Extract files matching a pattern:
    tar -xf source.tar --wildcards "*.html"
