An implementation of du(1) in Golang.
The purpose of this implementation is not to build a better du. It is to learn
Golang. I chose du because it serves a simple purpose - show how much space
files take up on disk. But from an educational perspective it provides several
good learning opportunities:
- how to work with command-line options and switches
- how to work with the file system
- concurrency, maybe?
- error handling
- unit testing
There are a lot of comments in the code, this is on purpose. Don't forget - this is a learning exercise.
The implementation is POSIX compatible. Other implementations exist, such as the one from GNU coreutils: https://www.gnu.org/software/coreutils/du.
If you want to learn together, ask a question, offer help or get in touch for any other reason please don't hesitate to contact me [email protected].
