 Dust is meant to give you an instant overview of which directories are using disk space without requiring sort or head. Dust will print a maximum of 1 'Did not have permissions message'.

-Dust will list the terminal height - 10 biggest sub directories or files and will smartly recurse down the tree to find the larger ones. There is no need for a '-d' flag or a '-h' flag. The largest sub directory will have its size shown in *red*

 ## Usage

 ```
-Usage: dust
 Usage: dust <dir>
 Usage: dust <dir>  <another_dir> <and_more>
 Usage: dust -p <dir>  (full-path - does not shorten the path of the subdirectories)
 Usage: dust -s <dir>  (apparent-size - shows the length of the file as opposed to the amount of disk space it uses)
 Usage: dust -n 30  <dir>  (Shows 30 directories not 20)
 Usage: dust -d 3  <dir>  (Shows 3 levels of subdirectories)
-Usage: dust -r  <dir>  (Reverse order of output, with root at the lowest)
-Usage: dust -x  <dir>  (Only show directories on same filesystem)
-Usage: dust -X ignore  <dir>  (Ignore all files and directories with the name 'ignore')
-Usage: dust -b <dir>  (Do not show percentages or draw the ASCII bars)

+## Performance
+
+Dust is currently about 4 times slower than du.

 ## Alternatives

 * [NCDU](https://dev.yorhel.nl/ncdu)
-* [dutree](https://github.com/nachoparker/dutree)
 * du -d 1 -h | sort -h

 Note: Apparent-size is calculated slightly differently in dust to gdu. In dust each hard link is counted as using file_length space. In gdu only the first entry is counted.
