search for files in a directory hierarchy

find [-H] [-L] [-P] [-D debugopts] [-Olevel] [path...] [expression]

-name pattern
       Base of file name (the path with the leading directories removed) matches shell  pattern  pattern.
       The  metacharacters  (`*',  `?',  and  `[]')  match a `.' at the start of the base name (this is a
       change in findutils-4.2.2; see section STANDARDS CONFORMANCE below).  To ignore  a  directory  and
       the  files  under  it,  use  -prune;  see  an example in the description of -path.  Braces are not
       recognised as being special, despite the fact that some shells including Bash imbue braces with  a
       special  meaning  in  shell  patterns.   The  filename  matching  is performed with the use of the
       fnmatch(3) library function.   Don't forget to enclose the pattern in quotes in order  to  protect
       it from expansion by the shell.

expr1 -o expr2
       Or; expr2 is not evaluated if expr1 is true.

expr1 -or expr2
       Same as expr1 -o expr2, but not POSIX compliant.

expr1 expr2
       Two expressions in a row are taken to be joined with an implied "and"; expr2 is not  evaluated  if
       expr1 is false.

expr1 -a expr2
       Same as expr1 expr2.

expr1 -and expr2
       Same as expr1 expr2, but not POSIX compliant.

-mtime n
       File's  data  was  last  modified  n*24  hours ago.  See the comments for -atime to understand how
       rounding affects the interpretation of file modification times.

-size n[cwbkMG]
       File uses n units of space.  The following suffixes can be used:

       `b'    for 512-byte blocks (this is the default if no suffix is used)

       `c'    for bytes

       `w'    for two-byte words

       `k'    for Kilobytes (units of 1024 bytes)

       `M'    for Megabytes (units of 1048576 bytes)

       `G'    for Gigabytes (units of 1073741824 bytes)

       The  size  does  not  count indirect blocks, but it does count blocks in sparse files that are not
       actually allocated.  Bear in mind that the `%k' and  `%b'  format  specifiers  of  -printf  handle
       sparse  files  differently.   The  `b'  suffix always denotes 512-byte blocks and never 1 Kilobyte
       blocks, which is different to the behaviour of -ls.

ACTIONS
    -delete
           Delete  files;  true if removal succeeded.  If the removal failed, an error message is issued.  If
           -delete fails, find's exit status will be nonzero (when it  eventually  exits).   Use  of  -delete
           automatically turns on the -depth option.

           Warnings:  Don't  forget  that  the  find  command  line is evaluated as an expression, so putting
           -delete first will make find try to delete everything below the  starting  points  you  specified.
           When  testing a find command line that you later intend to use with -delete, you should explicitly
           specify -depth in order to avoid later surprises.  Because  -delete  implies  -depth,  you  cannot
           usefully use -prune and -delete together.
