browsing your partition with tree via the command line
These tools are useful for development.
Most of the time you work on the terminal, and to find your way around a project you use things like find, ls, and tab completion.
If you need more of a bird’s eye view, you may fire up a gui browser like konqueror. But that’s a gui, and guis are for users.
Another option is tree. Here is example output of tree:
[leo@localhost devel]$ tree
.

What if you want to do something a tiny bit more intricate?
If you are working inside a cvs tree.. things can get pretty crazy.
Here is default tree output in a cvs filesystem hierarcy slice:

Wohoa.. that’s a lot of junk to look over.. What if we just want to see the roject files, not the cvs files..
Here’s what we can do, use the parameter -I CVS, this excludes things matching a pattern match:
[leo@localhost PDF-OCR]$ tree -I CVS
|-- INSTALL
|-- MANIFEST
|-- META.yml
|-- Makefile.PL
|-- PDF-OCR-1.02.tar.gz
|-- PDF-OCR-1.03.tar.gz
|-- PDF-OCR-1.04.tar.gz
|-- README
|-- bin
| |-- ocr
| |-- pdf2ocr
| |-- pdf2ocrturntotext
| `-- pdfgetext
|-- lib
| |-- Image
| | `-- OCR
| `-- PDF
| |-- OCR
| | |-- Thorough
| | | `-- Cached.pm
| | `-- Thorough.pm
| `-- OCR.pm

Pretty cool, huh?
It’s very useful to me when I’m busy on a more complex project and I need to get around, and I don’t want to use a damn gui to browse a filesystem section.
installing tree
Tree is not a standard command. You must install it with yum or build it on your machine.
