How to rename a file using the mv command in Linux? Many novices are not very clear about this. In order to help you solve this problem, the following editor will explain it in detail. People with this need can come and learn. I hope you can gain something.

Rename a file using the mv command

The mv command (short move time) is used to rename or move files from one location to another.

Basic syntax:

Mv [OPTIONS] source destination

Parameters:

Source: can be one or more files or directories

Destination: can be a single file or directory.

Description:

● if you specify more than one file source, the destination must be a directory. In this case, the source file is moved to the target directory.

● if a single file is specified as source and the destination target is an existing directory, the file is moved to the specified directory.

● to rename a file, you need to specify a single file as source and a single file as the destination target.

For example, to rename the file file1.txt to file2.txt, execute the following command:

Mv file1.txt file2.txt

How do I rename multiple files using the mv command?

The mv command can only rename one file at a time, but it can be used in conjunction with other commands, such as find to rename multiple files in a bash for or while loop.

Example: how to rename all .html files in the current directory and change the .html extension to .php by using the bash for loop.

For f in * .html; do mv-- "$f"${f%.html} .php" done

Let's analyze the code line by line:

The first line of ● creates a for loop and iterates through a list of all files. Html.

The second line of ● applies to moving each item and file in the list to a new replacement. Html with .php. This section ${file%.html} removes parts from the file name using the shell parameter extension. Html.

The ● done indicates the end of the loop segment.

We can also use the command find in combination with mv to achieve the same function as above.

Find. -depth-name "* .html"-exec sh-c'f = "{}"; mv-- "$f"${f%.html} .php"'\

The find command uses this switch to pass all the files mv whose .html ends in the current directory to the command-exec one by one. The string {} is the name of the file currently being processed.

As you can see in the above example, renaming multiple files with this mv command is not an easy task because it requires a good understanding of Bash scripts.
