search for files in a directory hierarchy
|
Before a command is executed, its input and output may be redirected using a special notation interpreted
by the shell. Redirection may also be used to open and close files for the current shell execution
environment. The following redirection operators may precede or appear anywhere within a simple command
or may follow a command. Redirections are processed in the order they appear, from left to right.
Redirecting Input
Redirection of input causes the file whose name results from the expansion of word to be opened for
reading on file descriptor n, or the standard input (file descriptor 0) if n is not specified.
The general format for redirecting input is:
[n]<word

Redirecting Output
Redirection of output causes the file whose name results from the expansion of word to be opened for
writing on file descriptor n, or the standard output (file descriptor 1) if n is not specified. If the
file does not exist it is created; if it does exist it is truncated to zero size.
The general format for redirecting output is:
[n]>word
If the redirection operator is >, and the noclobber option to the set builtin has been enabled, the
redirection will fail if the file whose name results from the expansion of word exists and is a regular
file. If the redirection operator is >|, or the redirection operator is > and the noclobber option to
the set builtin command is not enabled, the redirection is attempted even if the file named by word
exists.

-type c
File is of type c:
b block (buffered) special
c character (unbuffered) special
d directory
p named pipe (FIFO)
f regular file
l symbolic link; this is never true if the -L option or the -follow option is in effect,
unless the symbolic link is broken. If you want to search for symbolic links when -L is in
effect, use -xtype.
s socket
D door (Solaris)

-exec command ;
Execute command; true if 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 current file name being processed everywhere 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 quoted to protect them from expansion by
the shell. See the EXAMPLES section for examples of the use of the -exec option. The specified
command is run once for each matched file. The command is executed in the starting directory.
There are unavoidable security problems surrounding use of the -exec action; you should use the
-execdir option instead.
-exec command {} +
This variant of the -exec action runs the specified command on the selected files, but the command
line is built by appending each selected file name at the end; the total number of invocations of
the command will be much less than the number of matched files. The command line is built in much
the same way that xargs builds its command lines. Only one instance of `{}' is allowed within the
command. The command is executed in the starting directory.
