For those who are new to this like me, the hardest bit I've found with managing my seedbox via CLI is not knowing where my space goes.
I've found a handy little tool call ncdu that lets you browse the file system and see directory sizes:
Description: ncurses disk usage viewer
Ncdu is a ncurses-based du viewer. It provides a fast and easy-to-use interface
through famous du utility. It allows one to browse through the directories and
show percentages of disk usage with ncurses library.
it's in the ubuntu repositroy, so a simple apt-get install will grab it if you want to check it out.
What other cool little programs have you guys found along the way that have made your maintenance easier?
