[SOLVED] Curl Option to Rename Duplicate File Names During Download

Issue

Is there an option for curl to automatically change the downloaded file's filename if that filename already exists on disk?

Wget does this automatically by appending a .1, .2, .3, .4 etc... to the end of the file name.

Curl Example:

$ ls -al
drwx------. 3 user    user       219 Sep  6 17:12 .
drwxr-xr-x. 3 user    user        21 May 12 18:54 ..
-rw-rw-r--. 1 user    user    147415 Sep  6 16:47 image.jpg

$ curl -O https://website/context/path/image.jpg

$ ls -al
drwx------. 3 user    user       219 Sep  6 17:12 .
drwxr-xr-x. 3 user    user        21 May 12 18:54 ..
-rw-rw-r--. 1 user    user    147415 Sep  6 17:35 image.jpg

The above curl command will overwrite the original image.jpg. Is there a way in curl to cause the new file to be named image.jpg.1, or something similar, like in wget?

Wget Example:

$ rm image.jpg*
$ wget https://website/context/path/image.jpg

$ ls -al
drwx------. 3 user    user       219 Sep  6 17:12 .
drwxr-xr-x. 3 user    user        21 May 12 18:54 ..
-rw-rw-r--. 1 user    user    147415 Sep  6 17:42 image.jpg

$ wget https://website/context/path/image.jpg
$ wget https://website/context/path/image.jpg
$ wget https://website/context/path/image.jpg

$ ls -al
drwx------. 3 user    user       219 Sep  6 17:12 .
drwxr-xr-x. 3 user    user        21 May 12 18:54 ..
-rw-rw-r--. 1 user    user    147415 Sep  6 17:42 image.jpg
-rw-rw-r--. 1 user    user    147415 Sep  6 17:42 image.jpg.1
-rw-rw-r--. 1 user    user    147415 Sep  6 17:42 image.jpg.2
-rw-rw-r--. 1 user    user    147415 Sep  6 17:42 image.jpg.3

Solution

Nope. curl has no such option. If you really need it, you can most often work around it by doing the check yourself in a script or other wrapper program.

This feature is mentioned in curl's TODO as something that would be neat to have, so it might be added at a future point in time...
