https://github.com/tldr-pages/tldr  按照步骤了吗

我是 apt-get  install tldr

deepin@deepin:~$ tldr tar                                                                                      
tar
Archiving utility.Often combined with a compression method, such as gzip or bzip.More information: https://www.gnu.org/software/tar.

 - Create an archive from files:
   tar cf {{target.tar}} {{file1}} {{file2}} {{file3}}                                                         
                                                                                                    
 - Create a gzipped archive:
   tar czf {{target.tar.gz}} {{file1}} {{file2}} {{file3}}                                          
                                                                                                    
 - Create a gzipped archive from a directory using relative paths:
   tar czf {{target.tar.gz}} -C {{path/to/directory}} .                                             
                                                                                                    
 - Extract a (compressed) archive into the current directory:
   tar xf {{source.tar[.gz|.bz2|.xz]}}                                                              
                                                                                                    
 - Extract a (compressed) archive into the target directory:
   tar xf {{source.tar[.gz|.bz2|.xz]}} -C {{directory}}
