search for files in a directory hierarchy
|
find [-H] [-L] [-P] [-D debugopts] [-Olevel] [path...] [expression]
|
-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)

-iname pattern
Like -name, but the match is case insensitive. For example, the patterns `fo*' and `F??' match
the file names `Foo', `FOO', `foo', `fOo', etc. In these patterns, unlike filename expansion by
the shell, an initial '.' can be matched by `*'. That is, find -name *bar will match the file
`.foobar'. Please note that you should quote patterns as a matter of course, otherwise the shell
will expand any wildcard characters in them.

-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.

print lines matching a pattern
|
-i, --ignore-case
Ignore case distinctions in both the PATTERN and the input files. (-i is specified by POSIX.)
|
grep searches the named input FILEs (or standard input if no files are named, or if a single hyphen-minus
(-) is given as file name) for lines containing a match to the given PATTERN. By default, grep prints
the matching lines.
