This example finds all the files under /etc directory which are larger than 100k: root@ubuntu# find /etc -size +100k /etc/ssh/moduli /etc/ssl/certs/ca-certificates.cr /etc/bash_completio If we look at their sizes, they really are above 100k: root@ubuntu# ls -l /etc/ssh/moduli /etc/ssl/certs/ca-certificates.crt /etc/bash_completio -rw-r--r-- 1 root root 215938 Apr 10  2007 /etc/bash_completion -rw-r--r-- 1 root root 132777 Feb 19  2007 /etc/ssh/moduli -rw-r--r-- 1 root ro...
