If you work with files on the command line in Linux, renaming files is one of the most frequent tasks you may find yourself involved in. We’ve already discussed the\u00a0mv command<\/a> that lets you do this. And here, in this tutorial, we will discuss another such tool, dubbed rename.<\/p>\n

But before we start with that, it’s worth mentioning that all examples in this article have been tested on an Ubuntu 18.04 LTS machine.<\/p>\n

Linux rename command<\/h2>\n

As the name suggests, the rename<\/em> command in Linux allows you to rename files. Following is its syntax:<\/p>\n

rename [options] expression replacement file...<\/code><\/pre>\n
And here’s how the tool’s man page explains it:<\/p>\n
rename will rename the specified files by replacing the first occurrence of expression in their name by replacement.<\/code><\/pre>\n
Note that if you don’t have the rename command installed, you can get it using the following command:<\/p>\n
sudo apt install rename<\/code><\/pre>\n
Following are some Q&A-styled examples that should give you a better idea on how the rename command works.<\/p>\n
Q1. How to use rename command?<\/h2>\n
Basic usage isn’t exactly straight forward, I must say, but it’s not difficult to understand. Let’s say you have a file named ‘test.txt’ and you want to rename it to ‘new.txt’. Then here’s how you use the rename command to do this.<\/p>\n
rename 's\/test\/new\/' test.txt<\/code><\/pre>\n
Q2. How rename handles symbolic links?<\/h2>\n
By default, the rename command just renames the file which is passed as input, even if it’s a symbolic link. However, if you want the tool to not rename symbolic links, but act on their targets instead, then use the -s command line option.<\/p>\n
So if symlink.txt is a symbolic link that points to root.txt, then the following command will make sure the rename operation happens for root.txt:<\/p>\n
rename -s 's\/root\/new\/' symlink.txt<\/code><\/pre>\n
Q3. How to make a dry run with rename?<\/h2>\n
Suppose you only want to see the final change that’ll happen with a rename command, without actually carrying it out, then use the -n command line option. For example, the following command:<\/p>\n
rename -n 's\/new\/test\/' new.txt<\/code><\/pre>\n
produced the following output:<\/p>\n
rename(new.txt, test.txt)<\/code><\/pre>\n
but didn’t\u00a0actually rename new.txt to test.txt.<\/p>\n
Q4. How rename handles overwriting of files?<\/h2>\n
By default, the rename command doesn’t perform the operation if it involves overwriting an existing file. However, you can force the tool to overwrite using the -f command line option.<\/p>\n
For example, the following command:<\/p>\n
rename 's\/new\/test\/' new.txt<\/code><\/pre>\n
produced the following output:<\/p>\n
new.txt not renamed: test.txt already exists<\/code><\/pre>\n
But when the -f command was used:<\/p>\n
rename -f 's\/new\/test\/' new.txt<\/code><\/pre>\n
The operation completed smoothly and test.txt got overwritten.<\/p>\n
Conclusion<\/h2>\n
The rename command doesn’t offer too many options, and we’ve already discussed some of the main ones here. After you’re done practicing these, head to the tool’s\u00a0man page<\/a> to learn more about it.<\/p>\n","protected":false},"excerpt":{"rendered":"
