This article mainly explains "the usage of mv command in linux". Interested friends may wish to have a look at it. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn the usage of the mv command in linux.

1. Command format:

Mv [options] Source file or directory destination file or directory

2. Command function:

Depending on the type of the second parameter in the mv command (whether it is the target file or the target directory), the mv command renames the file or moves it to a new directory. When the second parameter type is a file, the mv command finishes renaming the file. At this point, there can be only one source file (or source directory name), which renames the given source file or directory to the given destination file name. When the second parameter is an existing directory name, there can be multiple source files or directory parameters, and the mv command moves the source files specified by each parameter to the destination directory. When moving a file across a file system, mv copies and then deletes the original file, and the link to the file is lost.

3. Command parameters:

-b: if you need to overwrite the file, overwrite the previous backup.

-f: force force means that if the target file already exists, it will be overwritten without being asked.

-I: if the target file (destination) already exists, it will be asked whether to overwrite it!

-u: if the target file already exists and the source is relatively new, it will be updated (update)

-t:-- target-directory=DIRECTORY move all SOURCE arguments into DIRECTORY, that is, specify the destination directory of the mv. This option is suitable for moving multiple source files to a directory, where the destination directory comes first and the source file comes after.

4. Command example:

Example 1: file renaming

Command:

Mv test.log test1.txt

Output:

The code is as follows:

The content of log3.txt directly covers the content of log2.txt.-f this is a dangerous option. Be sure to keep a clear mind when using it. In general, it is best not to add it.

Drwxr-xr-x 2 root root 4096 10-25 17:56 test5-1

[root@localhost test5] # mv log1.txt-b log2.txt

Mv: does it overwrite "log2.txt"? Y

[root@localhost test5] # ll

Drwxr-xr-x 2 root root 4096 10-25 17:56 test5-1

[root@localhost test5] #

Description:

-b does not accept parameters, mv will read the environment variable VERSION_CONTROL as the backup strategy.

-- backup this option specifies the action if the destination file exists, there are four backup strategies:

1.CONTROL=none or off: no backup.

2.CONTROL=numbered or t: numbered backup

3.CONTROL=existing or nil: if there is a numbered backup, continue with the numbered backup mnumbered 1.. n:

The numbered file log2.txt.~1~, already exists before the mv operation is performed, so execution again will result in log2.txt~2~, and so on. If there are no numbered files before, use the simple backup described below.

4.CONTROL=simple or never: use a simple backup: a simple backup is made before it is overwritten, there can be only one simple backup, and when it is overwritten again, the simple backup is overwritten.
