"gt5" or "where has my diskspace gone?"
\___________________________________________/
Overview
~~~~~~~~
Years ago, I was proud to own an 80MHz, 16MB RAM PC with a huge 512MB
harddisk. But even on this incredibly huge harddisk, my diskspace seemed
to disappear over time. So I wrote a little tool to find out where all my
diskspace had gone: I called it "gettree", as it showed all files in a
directory and also calculated the size of subtrees. Over the years, the
OS I used changed, but the problem stayed. Using Linux, there are some
tools to deal with it, but I couldn't find anything that was clearly laid
out, intuitive to browse, and doesn't need X-Windows.
Features
~~~~~~~~
* displays the diskspace used by files and directories within a directory
* displays what has happened since gt5 last ran (see screenshot below)
* optionally provides links to the files, so you can also browse them
* displays entries with their size and the percentage of their parent
* omission of small files/directories to keep the results readable
* easy browsing through subdirectories, using the cursor-keys
Implementation
~~~~~~~~~~~~~~
I tried different ways to do the job and settled on a small shell-script:
* highly 'portable', as it only depends on some GNU-utilities
* common textbrowsers are used to navigate through the results
* runs on console, xterm or remotely over ssh

Navigation
~~~~~~~~~~
If you are familiar with textbrowsers there is nothing to say: gt5 produces
an HTML file; go browse it. Below are the most important keys for gt5 used
with links/links2/elinks/lynx:
.---------------------------------------------------.
| browsing in general | meaning in gt5 |
======================================================================
| Cursor Left | go back | go one directory up |
|----------------|-------------------------|-------------------------|
| Cursor Right | follow link | open selected directory |
|----------------|-------------------------|-------------------------|
| Cursor Up/Down | go to link above/below | move Cursor Up/Down |
|----------------|-------------------------|-------------------------|
| Insert/Delete | scroll page up/down | scroll page up/down |
|----------------|-------------------------|-------------------------|
| Ctrl-C | quit textbrowser | quit gt5 |

Usage
~~~~~
Syntax: gt5 [ dir | file | dir file | file file2 ] [options]
dir the directory you want to check for space used
file/file2 existing du-logs (du -akx $DIR #gz/bz2/plain)
--cut-at float don't show files below 'float'% of its parent,
default is 0.1, use values between 0.01 and 30
--diff-dir d use dir d to store diffs between runs [~/.gt5-diffs]
--discard do not save this one for diffs, discard it
--link-files insert links to files for direct access
--max-depth i ignore anything deeper than i directories [5]
--max-lines i only consider the i biggest files [10000]
--no-diffs use this if you really do not want diffs
--save-as file DEPRECATED, use 'du', see manpage
--save-state overwrite a previous '--discard'
--with-mounts also look below mountpoints
