Any file in unix that starts with a ".", like .profile, is a hidden file. That's how that works
to include these files in your find:
ls -a
find txt in file
$ find . -name "*.log" -exec grep -l "addQuickDepositAccounts" {} \;
find file by name
$ find . -name "rc.conf" -print
$ find . -name "event*.jar"
Fine a filename that contains properties
$ find . -print | grep properties
Find a string in all directories for a string.
$ find . -exec grep "string" {} /dev/null \;
