Finding what's using all the space in *nix

ncdu

Is just great: CLI, ncurses based, fast, simple. Install it with sudo apt install ncdu.

I personally like to use du -sh * to see how big each directory is within the current directory.

Also you can sort to have bigger folders first: du -shx * | sort -hr. For du:

• -s, --summarize: display only a total for each argument
• -h, --human-readable: print sizes in human readable format (e.g., 1K 234M 2G)
• -x, --one-file-system: skip directories on different file systems

For sort:

• -h, --human-numeric-sort: compare human readable numbers (e.g., 2K 1G)

basically you can use the du command. something like this

du -a /home | sort -rn |head -1

please look at the man page or info du for more options.

Or, you can use GNU find.

find /home/ -type f -printf "%s:%p\n" | sort -t":" -rn| head -1
