Use JavaScript for Automation to rename files in batch!
While working on some client-side code at Oozou, I often have to rename a lot of image files.
For example, Bourbon uses _2x.png for retina images, rather than @2x.png used by Retina.js.
I used to do this manually, until I am fed up and write this script.
| var app = Application.currentApplication() | |
| app.includeStandardAdditions = true | |
| var Finder = Application('Finder') | |
| var selection = [].slice.call(Finder.selection()) | |
| var code = prompt('How to modify the name?', 'return name') | |
| var fn = new Function('name', code) | |
| try { | |
| var tasks = selection.map(function(item) { | |
| var name = item.name() | |
| try { | |
| var target = fn(name) | |
| } catch (e) { | |
| throw new Error('Cannot rename "' + name + '": ' + e) | |
| } | |
| if (!target) { | |
| throw new Error('Cannot rename "' + name + '": expression returned empty result') | |
| } | |
| return { item: item, from: name, to: target } | |
| }).filter(function(task) { return task.from != task.to }) | |
| if (tasks.length == 0) throw new Error('No files to rename!') | |
| var message = 'These files will be renamed:\n\n' + | |
| tasks.map(function(task) { return '- ' + task.from + ' => ' + task.to }).join('\n') | |
| if (confirm(message)) { | |
| tasks.forEach(executeTask) | |
| } | |
| } catch (e) { | |
| alert('Error!', String(e)) | |
| } | |
| // Recipes from: https://github.com/dtinth/JXA-Cookbook/wiki/User-Interactions | |
| function prompt(text, defaultAnswer) { | |
| var options = { defaultAnswer: defaultAnswer || '' } | |
| try { | |
| return app.displayDialog(text, options).textReturned | |
| } catch (e) { | |
| return null | |
| } | |
| } | |
| function alert(text, informationalText) { | |
| var options = { } | |
| if (informationalText) options.message = informationalText | |
| app.displayAlert(text, options) | |
| } | |
| function confirm(text) { | |
| try { | |
| app.displayDialog(text) | |
| return true | |
| } catch (e) { | |
| return false | |
| } | |
| } | |
| function executeTask(task) { | |
| task.item.name = task.to | |
| } |
I think you are already solved. But also if you need more facility with the batch name files- than kindly search on google by this keyword- BatchRenameFiles Tool. You will get the solve. I hope you will become happy by using the software of BatchRenameFiles Tool.

Hi, I just stumbled upon this is snippet and it is truly awesome.
Would it be okay if I used it in my own (open source, non-commercial) project, of course with crediting? ( https://github.com/chrisgrieser/finder-vim-mode )
please feel free! @chrisgrieser
I'm not sure who wrote this script, but I first want to thank him/her for sharing. Much appreciated.
To deal with the issue above (you can expect a lot of JXA newbees), may I suggest:
(1) Add a section in the header comments for "How to Use"
(2) ADD a user selection validation test, and alert the user if no files have been selected in the Finder, and advise him/her that is required before running the script.
(3) You could also run the chooseFile method if the user does not make and Finder selections:
chooseFile
[withPrompt: text] : the prompt to be displayed in the dialog box
[ofType: list of text] : a list of file types or type identifiers. Only files of the specified types will be selectable.
[defaultLocation: alias] : the default file location
[invisibles: boolean] : Show invisible files and folders? (default is false)
[multipleSelectionsAllowed: boolean] : Allow multiple items to be selected? (default is false)
[showingPackageContents: boolean] : Show the contents of packages? (Packages will be treated as folders. Default is false.)
→ alias : the chosen file
