Optional. %p = file path Refer to http://linux.die.net/man/1/find for more about -printf formatting. ------------------------ sort -nr = sort numerically and reverse (higher values - most recent timestamp - first) head -n 5 = get only 5 first lines (change 5 to whatever you want) cut -f2- -d" " = trim first field (timestamp, used only for sorting) ------------------------ Very useful for building scripts for detecting malicious files upload and malware injections.

Sort ls output of all files in current directory in ascending order
Just the 20 biggest ones:
ls -la | sort -k 5bn | tail -n 20
A variant for the current directory tree with subdirectories and pretty columns is:
find . -type f -print0 | xargs -0 ls -la | sort -k 5bn | column -t
And finding the subdirectories consuming the most space with displayed block size 1k:
du -sk ./* | sort -k 1bn | column -t
