Linux File management Tools

Linux File management tools: CP, MV, RM

1, Cp:copy

Source file: Destination file

Single source copy: CP [OPTIONS] ... [-T] SOURCE DEST

If the dest (target) does not exist, the data stream is created and copied to the target file;

Eg: Copy the etc/passwd to/tmp/passwd.bak and the destination file does not exist, so it will be created automatically Passwd.bak

cp-v/etc/passwd/tmp/passwd.bak

if DEST (target) exists, then overwrite the target file;

Eg: the destination file is overwritten because the destination file already exists.

cp-v/etc/passwd/tmp/passwd.bak

Multi-source replication: CP [OPTION] ... SOURCE ... DIRECTORY

CP [OPTION] ...-t DIRECTORY SOURCE ...

If the dest does not exist: error;

if dest exists:

If Dest is a non-directory file: error;

if Dest is a directory file: Copy each file to the target directory separately and keep the original original;

Common options:                         

-I: Interactive replication, that is, before overwriting to remind users to confirm;

- F: Force overwrite the target file;

-R,-r: Recursive copy directory;

-D: Copies the symbolic link file itself, not the source file it points to;

-a:-dr--preserve=all, archive, for archiving;

--preserv=

Mode: Permissions

ownership: A group of owners and genera

timestamps: Time stamp

Context: Security label

xattr: Extended Properties
