Geek to Live: Visualize your hard drive usage - Lifehacker

Command line: du (disk usage)

Not so much into this whole graphical user interface thing? Command-line lovers can also use the du (disk usage) command to get an idea of what's taking up what. The -h parameter makes the file sizes human readable. From Cygwin on Windows, or the Mac Terminal, cd into your directory of interest and try:

$ du * -h

  

The output will look something like:

28M     FileFormatConverters.exe

28K     LH_Logo_Store_Image.jpg

32K     Lazy_Store_Image.jpg

5.3M    photos-for-flickr

52K     Travel form - small Word 03 - gtrapani.doc

28K     Travel form - small.docx

16K     emailnewgoogdocs.png



  

A few more du hints:

• To just see directory sizes, drop the star and just use du -h
• To sort the list of files by size, use du -h | sort -n
  
  du -k | sort -nr (Thanks for the correction, Dr. Drang!)

This article at Linux.com, Disk usage analysis and cleanup tools, also has more on du and other 'nix-based GUI tools.
