Files and directories are the building blocks of the operating system. As regular users, we interact with the files and directories on a daily basis. Often times we\u00a0rename or move files\u00a0from one location to another for better organization. Definitely, we can perform this operation using the Graphical User Interface (GUI). However, most Linux <\/a>users prefer to use the\u00a0mv command<\/strong>\u00a0due to its rich functionality.<\/p>\n

In this easy-to-understand guide, we will learn the basics of the\u00a0mv command<\/strong>. As the name suggests, the\u00a0mv command<\/strong>\u00a0is used to rename or move files and directories.<\/p>\n

In this guide, we will learn about the\u00a0mv command<\/strong>\u00a0using practical examples. Beginners can use these examples on a day-to-day basis while working with Linux systems.<\/p>\n

So let\u2019s get started.<\/p>\n

\"mv<\/p>\n

[ez-toc]<\/p>\n

mv Command Syntax<\/strong><\/h3>\n

The syntax of the\u00a0mv command<\/strong>\u00a0is similar to other Linux commands. At a high level, it is divided into two parts \u2013\u00a0options<\/strong>\u00a0and\u00a0arguments<\/strong>:<\/p>\n

mv [OPTIONS] <SOURCE> <DEST><\/strong><\/pre>\n
mv [OPTIONS] <SOURCE-1> <SOURCE-2> ... <DIRECTORY><\/strong><\/pre>\n
In the above syntax, the square brackets\u00a0([])<\/code>\u00a0represent the optional arguments whereas angular brackets\u00a0(<>)<\/code>\u00a0represent the mandatory arguments.<\/p>\n
1. How to Rename a File in Linux<\/h3>\n
The very basic use of the\u00a0mv command<\/strong>\u00a0is to rename a file. So let\u2019s see how to rename a file from the current directory.<\/p>\n
First, create a sample file using the\u00a0touch command:<\/p>\n
touch file-1.txt<\/strong><\/pre>\n
Now, let\u2019s rename the file using the\u00a0mv command<\/strong>\u00a0as follows:<\/p>\n
mv file-1.txt file-2.txt<\/strong><\/pre>\n
Finally, verify that the file has been renamed successfully using the\u00a0ls command<\/a>:<\/p>\n
ls -1<\/strong><\/pre>\n
2. Enable Verbose Mode in Mv Command<\/h3>\n
Sometimes, we want to know which files or directories are getting renamed. In such cases, we can use\u00a0-v<\/code>\u00a0option to enable the verbose mode.<\/p>\n
To understand this, let\u2019s rename the file using the verbose mode:<\/p>\n
mv -v file-2.txt file-1.txt<\/strong><\/pre>\n
renamed 'file-2.txt' -> 'file-1.txt'<\/strong><\/pre>\n
In the above output, we can see that, now the mv command shows the rename message.<\/p>\n
<\/span>3. How to Rename a Directory in Linux<\/strong><\/h3>\n
Similar to files, we can use the\u00a0mv command<\/strong>\u00a0to rename the directory. To understand more clearly, first you need to\u00a0create a new directory\u00a0with the name\u00a0src<\/strong>:<\/p>\n
mkdir src<\/strong><\/pre>\n
Now, let\u2019s rename the directory using the following command:<\/p>\n
mv -v src dst<\/strong><\/pre>\n
renamed 'src' -> 'dst'<\/strong><\/pre>\n
 <\/p>\n
4. How to Move Multiple Files to the Directory<\/strong><\/h3>\n
Many times, we move files to a single directory for better organization. For example, it is very common practice to keep all audio files in a single directory.<\/p>\n
Certainly, we can use the\u00a0mv command<\/strong>\u00a0multiple times to achieve this. However, the process quickly becomes time-consuming as files increase in number. However, to make it time-efficient, we can use the alternative syntax of the\u00a0mv command<\/strong>.<\/p>\n
Let\u2019s understand by creating a few files and a new directory:<\/p>\n
touch 1.mp3 2.txt 3.dat<\/strong><\/pre>\n
mkdir misc<\/strong><\/pre>\n
Now, let\u2019s move all these files to the\u00a0misc<\/strong>\u00a0directory using the following command:<\/p>\n
mv -v 1.mp3 2.txt 3.dat misc<\/strong><\/pre>\n
renamed '1.mp3' -> 'misc\/1.mp3'\r\nrenamed '2.txt' -> 'misc\/2.txt'\r\nrenamed '3.dat' -> 'misc\/3.dat'<\/strong><\/pre>\n
 <\/p>\n
It is important to note that, to use this alternative syntax the directory must be present already and it must be the last argument of the command.<\/p>\n
<\/span>5. How to Move Multiple Directories in Linux<\/strong><\/h3>\n
Just like the files, we can use the\u00a0mv command<\/strong>\u00a0to move multiple directories at once. Let\u2019s understand this with a simple example.<\/p>\n
First, create a few directories using the\u00a0mkdir command:<\/p>\n
mkdir dir-1 dir-2 dir-3 dir-4<\/strong><\/pre>\n
Now, let\u2019s move all these directories to the\u00a0dir-4<\/strong>\u00a0directory:<\/p>\n
mv -v dir-1 dir-2 dir-3 dir-4<\/strong><\/pre>\n
In the above output, we can see that we were able to move all directories.<\/p>\n
<\/span>6. How to Avoid Overwriting Files in Linux<\/strong><\/h3>\n
By default, the\u00a0mv command<\/strong>\u00a0overwrites the destination file. Sometimes, we want to disable this default behavior to avoid data loss. In such cases, we can use the\u00a0-n<\/code>\u00a0option.<\/p>\n
To understand this, first, create a sample file:<\/p>\n
touch file-2.txt<\/strong><\/pre>\n
Now, let\u2019s try to overwrite it using the following command:<\/p>\n
mv -v -n file-1.txt file-2.txt<\/strong><\/pre>\n
Here, we can see that verbose mode didn\u2019t show any message. This indicates that\u00a0file-2.txt<\/strong>\u00a0hasn\u2019t been overwritten.<\/p>\n
<\/span>7. How to Overwrite Files Interactively in Linux<\/strong><\/h3>\n
In the previous example, we saw how to disable file overwriting. However, sometimes we want to overwrite files in a safe manner.<\/p>\n
In such cases, we can use the\u00a0mv command<\/strong>\u00a0in an interactive mode. In this mode, the\u00a0mv command<\/strong>\u00a0shows the warning message and waits for the user\u2019s confirmation before overwriting the file.<\/p>\n
Now, let\u2019s try to overwrite the\u00a0file-2.txt<\/strong>\u00a0file in an interactive mode:<\/p>\n
mv -v -i file-1.txt file-2.txt\r\n\r\nmv: overwrite \u2018file-2.txt\u2019?<\/strong><\/pre>\n
In the above output, we can see that the command is waiting for the user\u2019s confirmation. Just like other Linux commands, we can use\u00a0'y'<\/code>\u00a0to continue or\u00a0'n'<\/code>\u00a0to abort the operation.<\/p>\n
<\/span>8. Overwrite File Only When the Source Is Newer<\/strong><\/h3>\n
In the previous example, we saw how to overwrite files using an interactive mode, but this method is not practical when we want to overwrite a large number of files.<\/p>\n
However, we should not perform the overwrite operation without verification, because a user might overwrite the newer file accidentally. In such cases, we can use the\u00a0-u<\/code>\u00a0option to perform the move operation only if the source is newer than the destination.<\/p>\n
To understand this, let\u2019s update the timestamp of the source file:<\/p>\n
touch -t 201912301000 file-1.txt<\/strong><\/pre>\n
ls -l file-1.txt<\/strong><\/pre>\n
In the above example, we have used the\u00a0-t<\/code>\u00a0option of the\u00a0touch command\u00a0to set the older timestamp on the\u00a0file-1.txt<\/strong>\u00a0file.<\/p>\n
Next, let\u2019s update the timestamp of the destination file to the current time:<\/p>\n
touch file-2.txt<\/strong><\/pre>\n
Finally, let\u2019s try to perform overwrite the destination file using the\u00a0-u<\/code>\u00a0option:<\/p>\n
mv -v -u file-1.txt file-2.txt<\/strong><\/pre>\n
In the above output, we can see that verbose mode didn\u2019t show any message. This indicates that\u00a0file-2.txt<\/strong>\u00a0hasn\u2019t been overwritten.<\/p>\n
9. How to Create a Backup Before Overwriting Files<\/strong><\/h3>\n
In the previous few examples, we saw how to overwrite the destination file in a safer way. The mv command provides one more option, which allows us to specify a backup policy using the\u00a0--backup<\/code>\u00a0option, which takes a backup of the destination file before overwriting it.<\/p>\n
touch file-1.txt file-2.txt<\/strong><\/pre>\n
mv --backup=numbered -v file-1.txt file-2.txt<\/strong><\/pre>\n
Here, we have used the numbered backup policy, which uses incremental numbers in the backup file names.<\/p>\n
To understand this, let\u2019s execute these two commands a few more times and check the output:<\/p>\n
touch file-1.txt file-2.txt\r\nmv --backup=numbered -v file-1.txt file-2.txt\r\n\r\ntouch file-1.txt file-2.txt\r\nmv --backup=numbered -v file-1.txt file-2.txt\r\n\r\ntouch file-1.txt file-2.txt\r\nmv --backup=numbered -v file-1.txt file-2.txt<\/strong><\/pre>\n
 <\/p>\n
In this beginner\u2019s guide, we discussed how to rename and move files as well as directories using the\u00a0mv command<\/strong>. Linux newbies can refer to these examples in day-to-day life while working with Linux systems.<\/p>\n
