I was working on my last post and found out that I used a Linux command **tree** to take a screenshot of the directory structure, then I thought, Oh that was kinda cool. So I thought of writing a small post about it.

tree - Command

The tree command is a simple utility to visualize a directory structure and has few useful options.

• Display all files including hidden files

        
          tree -a
        
      

• Display only directories (the one used in the screenshot above)

        
          tree -d
        
      

• Limit the tree level (also used in the screenshot above)

        
          tree -L 2
        
      

• Colorize the output

        
          tree -C
        
      

• Similar command 'pstree' to view the running processes in a tree

        
          pstree [pid|username] # pid and username are optional, when omitted it displays all processes
