Third form:Existing-FileIs the directory path to be renamed;New-directoryIs the new path name of the directory for renaming or overwriting.

 

Option

Example MV

 
$MVDemo1.txt demo2.txt $LsDemo2.txt
 

Rename a file

 

MV-I

 
$LsDemo2.txt demo.txt $MVDemo2.txt-I demo.txtMV: Overwrite?"Demo.txt"? Y
 

Confirm before overwriting an existing file. Strings starting with Y or y indicate OK, and other arbitrary characters indicate no.

 

The name of the file that does not have the write permission for the music video.

$ Ls - L total usage  0 -RW-r -- 1 Root 0 January 8   13 : 31   CC -RW-r -- 1 Siu 0 January 8  13 : 24   Dd  $  MV   Dd   CC  MV : Overwrite? "  CC  " And ignore the permission mode 0644 (RW-r -- )? Y $  Ls  CC 

Here, all CC users and groups are root, and my current user is Siu. During overwriting, confirmation is required.

 

MV-F does not have the write permission for the file name

$Ls-L total usage0-RW-r --1Root0January8 13:34AA-RW-r --1Siu0January8 13:34Bb $MVBb-F AA $LsAA
 

The same as above, but the-F option is added here, which is enforced during overwrite without prompting

 

MV Mobile Directory

$LsAbc cde $MVCde abc $LsABC $ CD ABC/$LsCDE
 

Move the CDE directory to the ABC directory.

MV rename directory

 
$LsABC $MVABCDir$LsDir
 

Rename the ABC directory to the Dir directory. Mv ABC ../You can move ABC to the parent directory.

 

MV-u

$Ls-L total usage0-RW-r --1Siu0January8 13:43Time1.txt-RW-r --1Siu0January8 13:44Time2.txt $MVTime1.txt-U time2.txt $LsTime1.txt time2.txt
 

Confirm that the modified time is overwritten again. The modified time of time2.txtis later than the modified time of time1.txt, so overwriting failed.

 

MV-V

 
$MVTime1.txt-V time2.txt"Time1.txt"->"Time2.txt"$LsTime2.txt
 

Lists information about moving or overwriting.

 

MV-B

 
$MV-B aa.txt bb.txt $LsBb.txt~
 

Backup is performed during overwriting. The backup file is at the end ~

 

Tips

1. in Linux, the concept of overwrite and rename is almost the same. There is no such concept as rename in windows.

2. You can write the option in any location, mv aa-v bb, MV-v aa bb, or mv aa bb-v.
