-mtime n

File's data was last modified n*24 hours ago.
-name pattern

Baseoffile name (the path with the leading directories removed) matches shell pattern pattern.The metacharac-

ters ('*', '?', and '[]') do not match a '.' at the start of the base name.To ignore a directoryandthefiles

under it, use -prune; see an example in the description of -path.
-exec command ;

Executecommand;trueif 0 status is returned.All following arguments to find are taken to be arguments to the

command until an argument consisting of ';' is encountered.The string '{}' is replaced by the currentfilename

beingprocessedeverywhere it occurs in the arguments to the command, not just in arguments where it is alone, as

in some versions of find.Both of these constructions might need to be escaped (with a '\') or quotedtoprotect

them from expansion by the shell.The command is executed in the starting directory.
