Linux command-find {find}

An order to explain

Common example:find Path-option [-print] [-exec-ok command] {} \;

The directory path that the Path:find command looks for. For example, use. To represent the current directory, and/to represent the system root directory.

The-print:find command outputs the matched file to standard output.

The-exec:find command executes the shell command given by the parameter to the matching file. The corresponding command is in the form of ' command ' {} \;, note the space between {} and \;

-ok: The same as-exec, except that the shell command given by the parameter is executed in a more secure mode, prompting the user to determine whether to execute before executing each command.

#-print output the found file to the standard output #-exec command {} \; --the command operation of the file to be traced, {} and \; There are spaces #-ok and-exec the same, except to consult the user example before the operation: find. -name. SVN | Xargs RM-RF
