Linux file Management

CP, MV, RM

Copy command: CP

CP [Option] ... [-T] SRC (source) DEST (Purpose)

(If the target does not exist, a new dest is created and the content in Src is populated into dest.)

If the target exists: If Dest is a file, the SRC content is overwritten in dest. We recommend that you use the-i option for the CP command.

If Dest is a directory, create a new file with the same name as the original file under Dest and populate the contents of SRC with dest)

Example: Cp/etc/fstab/tmp/out.tmp (out.tmp as file)

Cp/etc/fstab/tmp/out (out for directory)

CP [Option] ... SRC (original file) ... (multiple files available) Directory (new directory) (which directory is copied to)

If SRC is a multiple file, directory must be present and directory, and other cases are wrong.

CP SRC DEST

SRC is the directory:

Use option at this time:-R (Recursive recursion)

Create the specified directory if dest does not exist, copy all directories in src directory to dest

If dest exists:

If the dest is a file, the error

If Dest is a directory, copy to this directory

Common options:

-I: Interactive

-R: Recursively replicate directories and all content inside them

-A: Archive, equivalent to-DR--preserv=all (that is, preserve the attributes of the source file or directory, including the owner, the owning group, the permissions and the time)

-D:--no-dereference--preserv=links (if the original file is a link, keep the original link format)

--preserv=[attr_list] (reserved property)

Mode: Permissions

Ownership: Belong to the main group

Timestamp: Time stamp

Links: Link

XATTR: Special Attributes

Context: Contexts

All: All

-P =--preserve=mode, ownership, timestamp

-V Show More information

-T can put the target in front when copying

-F--force forced replication (dangerous)

such as: Cp/etc/apache2/tmp/apache2 (/etc/apache2,/tmp/apache2 as directory,)

Cp-p/var/tmp/a.txt./temp/(Reserved property)

Move File command: MV

MV [Option] ... [_t] SOURCE DEST to move the original file to the target file, which is renamed

MV {Option] ... SOURCE ... Directory to move source files to the destination file directory

MV [Option] ...-t directory SOURCE takes directory as a mobile target

Option

-I interactive with prompt operation

-F Mandatory

such as: MV Test.log Test1.txt (renamed to Test.txt)

MV Test1.txt temp/(move to temp directory)

Delete command: RM

RM [OPTION] ... FILE ...

Common options:

-I: Interactive

-F: Force delete

-R: Recursive

Rm-f A.log (forcibly delete files)

Rm-r tmp/(delete tmp directory and its subdirectories and files)
