DirSize

DirSize is a simple directory reporting tool. It recursively scans the provided (or current) directory, and reports the number of files and director sizes of each sub-directory as well as the files in the directory.

You can sort by Directory name, Files, and Size, although Size is the default.

Maps:

One of the interesting things about DirSize is it shows a visual representation of the file sizes of counts. I call this a SizeMap or FilesMap and it's the area to the right of the output. If you sort by size (default or -ss) or directories (-sd) is will show the SizeMap. If sorted by file counts (-sf) the map will change to show a visual representation of the number of files per subdirectory.

Note:

Snap applications run in a container and by default do not have rights to see files. In order to use DirSize, it needs to be able see file names and sized. The interface system-backup gives it that right. Therefore, to use the system, you need to allow it by executing:

sudo snap connect dirsize:system-backup

If you change your mind, you can remove this permission by executing:

sudo snap disconnect dirsize:system-backup

Command-Line Options:

Usage:

java -jar dirsize.jar [-D] [-x <filename>] [-ss|-sf|-sd] [-r] [-c width] [-v] [-h|?] [Directory]

-D Run program in debug mode. This will display quite a bit of information on the program as it's running. I usually use this as I debug the program, but if you wish to get a bit more insight into what's going on, go for it.

-e Suppress the error display. Will not show directories dirsize couldn't read

-ss Sort output by the directory sizes. This is the default

-sf Sort output by the number of files

-sd Sort output by directory name

-r Reverse the sorting display

-x FileName Export the results as a CSV to the file provided

-c width On Windows, the current terminal width is set by default. On Linux, it is set to 100 while I look for a way to determine this automatically. You can, however, change this to whatever you'd like. Useful if you have a very wide console display. The minimum terminal display width is 60, but it's looks much better in the 100 character range.

-v Simply display the program version and exit

-h | -? Display the program help

Examples

java -jar dirsize.jar

Display a size sorted report from the current directory

java -jar dirsize.jar -sd C:\Apps

Display a directoyr name sorted report from the C:\Apps directory

java -jar dirsize.jar -c 80 -sf /home/jimbob

Display a file number sorted report from the jimbob's home dir using 100 columns

java -jar dirsize.jar -x $HOME/usr-output.csv /usr

Output the directory report of /usr into a CSV file in my home directory
