In this issue, the editor will bring you about the Linux system how to rename multiple files at a time. The article is rich in content and analyzes and describes for you from a professional point of view. I hope you can get something after reading this article.

Syntax: rename [- v-n-f]

Is a Perl-compatible regular expression that represents the file to be renamed and what to do. The regular expression is in the form of'sAccordLay _ name_ _ new _

The'- v 'option shows the details of the file name change (for example, rename XXX to YYY).

The'- n 'option tells the rename command to show that the file will be renamed without actually changing the name. This option is useful if you want to simulate a file name change without changing the file name.

The'- f 'option forces existing files to be overwritten.

Case demonstration: change the file extension

Suppose you have a lot of .jpeg picture files. You want to change their names to .jpg. The following command changes the .jpeg file to * .jpg.

/ .jpg /'* .jpeg

Change uppercase to lowercase, and vice versa

Sometimes if you want to change the case of the file name, you can use the following command.

Change all files to lowercase:

# rename'yUnix Amurazapa Muhamzono'*

Change all documents to uppercase:

# rename'yUniqa MuyzCompa Amurz Universe'*

Change the file name schema

Now let's consider more complex regular expressions that contain subpatterns. In PCRE, the subpattern is contained in parentheses, followed by a number (for example, 1 ~ 2).

For example, the following command turns' imgNNNN.jpeg' into 'danNNNN.jpg'.

# rename-v 's/img (\ d {4}) .jpeg$/dan$1.jpg/' * .jpeg

Img_5417.jpeg renamed as dan_5417.jpg

Img_5418.jpeg renamed as dan_5418.jpg

Img_5419.jpeg renamed as dan_5419.jpg

Img_5420.jpeg renamed as dan_5420.jpg

Img_5421.jpeg renamed as dan_5421.jpg

For example, the following command turns' img_000NNNN.jpeg' into 'dan_NNNN.jpg'.

# rename-v 's/img\ d {3} (\ d {4}). Jpeg$/dan$1.jpg/' * jpeg

Img_0005417.jpeg renamed as dan_5417.jpg

Img_0005418.jpeg renamed as dan_5418.jpg

Img_0005419.jpeg renamed as dan_5419.jpg

Img_0005420.jpeg renamed as dan_5420.jpg

Img_0005421.jpeg renamed as dan_5421.jpg

In the above example, the subpattern'\ d {4} 'captures four consecutive digits, and the four digits captured are $1, which will be used for the new file name.
