Recursively find top 20 largest files (> 1MB) sort human readable format

find . -type f -print0 | xargs -0 du -h | sort -hr | head -20
Search for files and list the 20 largest. find . -type f gives us a list of file, recursively, starting from here (.) -print0 | xargs -0 du -h separate the names of files with NULL characters, so we're not confused by spaces then xargs run the du command to find their size (in human-readable form -- 64M not 64123456) | sort -hr use sort to arrange the list in size order. sort -h knows that 1M is bigger than 9K | head -20 finally only select the top twenty out of the list
