# (pattern represents a filename string to look for, may also contain special regular expression characters)
-name pattern
# (replace c with a d, for directory or f, for a regular file)

# (allows you to execute commands on every file found by the find command, very useful. You can use the special token {} which represents the current filename)

Examples of using the find command

# returns all files matching the pattern created in the last 14 days
find -name 'var1*' -mtime -14

# returns all files over 14 days old
find -name 'var1*' -mtime +14

# finds all files matching the pattern and then executes the rm -R command on the file
# the final \ is necessary when using the -exec option because it signifies the end of the command you are trying to execute
find -name '_vti_cnf' -type d -exec rm -R {} \;
