Find is verstile and powerful. We can search files based of the permissions a file has. We can find by modification date or how long ago the file was created. Regex can also be added. Search based on text inside a file..
find /etc -name "motd"
will find files in the /etc directory where file name is “motd”
find /etc -name "motd*"
will find files in the /etc directory where file name starts with ‘motd’
By default, the -name flag is case sensitive. -iname will search by file name, case-insensitively.
