The Find command for Linux

The Linux Find command searches the directory structure for files and performs the specified actions.

Find command:

1. Command format:

Find Pathname-options [-print-exec-ok ...]

2. Command function:

Used to locate files in the file tree and make appropriate processing (possibly accessing the disk)

3. Command parameters:

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

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

3) 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 \;

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

b--block (512 bytes); c--byte; w--Word (2 bytes);

k--kilobytes; m--megabytes; g--gigabytes.

4) -type Find files of a certain type, such as:

B-block device files.

D-Directory.

C-character device file.

P-Pipeline file.

L-Symbolic link file.

F-Normal file.

a) Find .-type d Find files with file type directory

5) according to file Time to find

Each file in a Linux file system has three timestamps:

a ) Access Time (-atime): The last time a user accessed a file;

b modified Time (-mtime): The time the file content was last modified.

C Change Time (-ctime): The time the file metadata (metadata, such as permissions or ownership) was last changed.

-atime,-mtime,-ctime as the time parameter, the unit is day. You can use + to represent greater than,-represent less than (and the same as +,-based on file size lookups).

We're only here for-mtime example, and the other two timestamps are the same.

1.Find/-mtime +3 look for files that have been modified more than 3 days ago
