Recipe:Printing directory tree 

Create filesystem tree
========================

$ tree unixfs
unixfs/
|-- bin 
|   |-- cat 
|   `-- ls 
|-- etc 
|   `-- passwd 
|-- home 
|   |-- pactpub 
|   |   |-- automate.sh 
|   |   `-- schedule 
|   `-- slynux 
|-- opt 
|-- tmp 
`-- usr 
8 directories, 5 files 

Highlight files matched by pattern
===================================


$ tree path -P PATTERN # Pattern should be wildcard
Eg:
$ tree path -P "*.sh"
|-- home 
|   |-- pactpub 
|   |   `-- automate.sh 

Highlight files excluding pattern
=================================

$ tree path -I PATTERN

Print size along with files
==============================

$ tree -h

HTML output for tree
====================
$ tree unixfs -H http://localhost -o unixfs/out.html
