Find files greater than X value, sort by size, show in ls format

Question

My assignment is: Find files (in a specific directory that is given) , show only the ones above 100 megabytes, sort them by size, print them in ls -lh format.

This is what I execute:

find /home/it21366 -size +10M | sort -h | ls -lh

This is what I get

I can't imagine why LS seems to ignore the other methods, and simply shows the contents of the files unsorted and unfiltered.

ls does not use anything you're trying to pipe to it through standard input. Since its command line arguments are just the options -lh, it's listing the full contents of the current directory, in long format with human-optimized file sizes, in default alphanumeric sort order. You would need different options for ls to sort in different ways, e.g. by size, or to display the directory list unsorted. — telcoM, Dec 06 '18 at 12:56

use xargs:

find /home/it21366 -size +10M | xargs ls -lhsSr

On the assumption that there are no files named with spaces or tabs in them – Jeff Schaller Dec 06 '18 at 13:38

Another option, if the number of files is limited enough to fit in one (long) call to ls, would be to use find to find the large files and ls -S to do the sorting:

find /home/it21366 -type f -size +10M -exec ls -lS {} + 2>/dev/null

The -exec ... {} + tells find to replace the "found" files into the call to ls, fitting as many as it can. If there are too many files, you'll get multiple calls to ls and thus un-sorted results (they'll be sorted in groups). I also added -type f to restrict the matches to regular files.
