How to rename files using Keywords?

How to rename files using Keywords?
For example, I have 10 files with a 1080 key, 10 files with a 47434 keyword, and 10 more files with a 9484 keyword.
Can I rename these files to 1080_1, 1080_2... up to 1080_10,
47434_1...47434_10
There is no choice of Keyword in Batch Renaming, maybe there is another option?

You would have to use a script that reads keywords and renames files accordingly.

[Guest]

can you tell me where I can find a script or a specialist who can write it?

Ideally a custom script would do this in one step.

A multi-step process using existing scripts would be:

1) Use a script to copy keywords to description or title, which is supported by the batch rename metadata field. Scripts below. Info on how to save and install them here:

2) Rename using the accessible title or description metadata:

3) Use a string substitution regex find/replace to remove the auto numbering that is produced when duplicate files clash with the same name and replace with a sequence number:

if( BridgeTalk.appName == "bridge" ) {    
keysToDescription = MenuElement.create("command", "Keywords To Description", "at the end of Tools");  
    }  
keysToDescription.onSelect = function () {   
var sels = app.document.selections;  
for(var a in sels){  
md =sels[a].synchronousMetadata;   
md.namespace = "http://ns.adobe.com/photoshop/1.0/";   
var Keys =  md.Keywords.toString().replace(/,/g,', ');// Replace a comma with comma space  
md.namespace = "http://purl.org/dc/elements/1.1/";  
md.description ='';  
md.description = Keys;  
    }  
};

Keywords are in dc:subject, other namespaces such as photoshop, lr, and exif are optional.

I tried hacking the following script without much success:

It's very easy with ExifTool, here using a regular expression to replace comma/space with a hypen (depending on the keyword separators this may be a semi-colon with or without a space etc). One must be careful that filenames don't include invalid characters.

Mac OS:

exiftool '-FileName<${subject;s/, /-/}.%e' '/path to/file or/folder'

Win OS:

exiftool "-FileName<${subject;s/, /-/}.%e" "\path to\file or\folder"

There are other considerations, like error checking (because a long string of keywords wouldn't be a legal filename, and keywords can have illegal filename characters) and serialization because keywords aren't unique identifiers, and what if dc: subject and photoshop:Keywords aren't the same, and such and so.
