I have the command:
du /home | sort -nr +0 -1 | head -10
and need to know what each piece (“du”, “/home”, “|”, “sort”, “-nr”, “+0”, “-1”, “head”, and “10”) does.
I have the command: du /home | sort -nr +0 -1 | head -10

gives a list of the “Disk Usage” (thus the name of the command) of every directory in /home and, recursively, all sub-directories. One line output per directory. “|” sends the output to the next command.
Sorts the result, with “-n” specifying numeric (as opposed to lexicographic) sort, “r” specifies reverse order so the largest value appears first). “-nr” is equivalent to “-n -r”
Outputs only the first 10 lines of the previous command.
In essence it’s finding the 10 largest directories in /home.
