The following script displays a useful tree structure of a directory; it’s similar the old DOS-command: tree.

  find . -type d | sed -e "s/[^-][^\/]*\//  |/g" -e "s/|\([^ ]\)/|-\1/" | tee output_.txt       

As noted, three parts are combined:

  1. find : This command searches the directory tree rooted at each given file name by evaluating the given expression from left to right, according to the rules of precedence, until the outcome is known (the left hand side is false for and operations, true for or), at which point find moves on to the next file name.

  2. sed : (s)tream (ed)itor. A stream editor is used to perform basic text transformations on an input stream (a file or input from a pipeline). While in some ways similar to an editor which permits scripted edits (such as ed), sed works by making only one pass over the input(s), and is consequently more efficient. But it is sed’s ability to filter text in a pipeline which particularly distinguishes it from other types of editors. See ‘sed –help’ for usage information.

  3. tee : The command reads standard input, then writes its content to standard output. It simultaneously copies the result into the specified file(s) or variables.


  cd myDirectory/                                                                                  
  find . -type d | sed -e "s/[^-][^\/]*\//  |/g" -e "s/|\([^ ]\)/|-\1/" | tee output_.txt
