osx bash上的树命令

Question

我正在跟踪一个名为pry的红宝石宝石上的屏幕.在8:10,使用.tree命令,我相信这是一个Unix命令.

它似乎不适用于我的系统:

[24] pry(main)> .tree
\Error: there was a problem executing system command: tree

我已经将问题追溯到这里,其中pry引用了一个shell命令:

Pry::CommandSet.new do

  command(/\.(.*)/, "All text following a '.' is forwarded to the shell.", :listing => ".<shell command>") do |cmd|
    if cmd =~ /^cd\s+(.+)/i
      dest = $1
      begin
        Dir.chdir File.expand_path(dest)
      rescue Errno::ENOENT
        output.puts "No such directory: #{dest}"
      end

    else
      if !system(cmd)
        output.puts "Error: there was a problem executing system command: #{cmd}"
      end
    end
  end

从bash的上下文我尝试使用命令树没有运气:

projects/sms(apps2)$ tree
-bash: tree: command not found
~/projects/sms(apps2)$ .tree
-bash: .tree: command not found

这看起来非常有用,我怎么能得到这个命令？

Answer 1

使用自制软件:

brew install tree

使用macports:

sudo port install tree

使用来源:

按照这些指示.(警告;你应该使用有意义的标志/等.)

^{<rant>所有系统都应该附带tree; 我经常使用它.我们可以将目录结构发布为文本,而不是图片.</ rant>}

对于简单的方法，您还可以将以下别名添加到您的~/.bashrc或~/.zshrc文件：

alias tree="find . -print | sed -e 's;[^/]*/;|____;g;s;____|; |;g'"

这导致以下结果：

$ tree
.
|____.git
| |____config
| |____objects
| | |____pack
| | |____info
| |____HEAD
| |____info
| | |____exclude
| |____description
| |____hooks
| | |____commit-msg.sample
| | |____pre-rebase.sample
| | |____pre-commit.sample
| | |____applypatch-msg.sample
| | |____pre-receive.sample
| | |____prepare-commit-msg.sample
| | |____post-update.sample
| | |____pre-applypatch.sample
| | |____pre-push.sample
| | |____update.sample
| |____refs
| | |____heads
| | |____tags
