Photoshop script replacing linked smart objects based on layer "name string"

I need a photoshop script to do the following:

Open a Dialogue Box and have an option to...
 Replace linked smart objects labeled "RED" in the Name of the layer and update all linked smart objects associated with that color to "BLUE"
ex: "RED" will replace the following smart objects based on their name from the current file directory

Linked Smart Objects:
- RED_3D22
- RED_BLACK
- RED_FUTURE
- RED_WHITE
- RED_HUGOKNOTS_NEG
- RED_HUGOKNOTS_POS
- RED_MONOCHROME
- RED_MONOPLUS_BP

to these Linked Smart Objects from the same directory

- BLUE_3D22
- BLUE_BLACK
- BLUE_FUTURE
- BLUE_WHITE
- BLUE_HUGOKNOTS_NEG
- BLUE_HUGOKNOTS_POS
- BLUE_MONOCHROME
- BLUE_MONOPLUS_BP

 

** If smart object above does not exist in the existing PSD, it will ignore and continue executing the script til completion.

that is all, no exporting or saving, just swapping.

any help is appreciated.

This "Relink All Smart Object Layers Using New Name Prefix.jsx" variation will process all linked smart object layers found inside layer groups/nested layer groups (not only root/top-level layers):

Note: The case-insensitive colour name prefix replaces the linked file with another file in the same directory with a different colour prefix name -

From: blue_rectangle.psd
      blue_circle.psd

To:   red_rectangle.psd
      red_circle.psd

There is no need to type the underscore _ separator character (although it has to exist in the filename) and the replacement image should have the same resolution and file format as the smart objects

First of all, thank you for your reply and attempt at this.

While the script works, I am trying to have it look for instances for a replacement of all smart objects.

example, imagine the folder has "GREEN_CIRCLE", or "PURPLE" CIRCLE, etc. Ideally I would like to 

have the script locate the directory and replace the prefix name along with what type of object it is.

ex:

script would search "red" and identify any object labeled "red" and replace objects based on

the remaining string (_circle, or _square) 

I am going to build a PSD that will have over 20 smart objects, and would like to auto replace in 1 swoop

rather than having to manually select the replacements. so basically all smart objects will have the same ending text, only change would be the text aka red, green, blue, purple, etc etc.

if that is possible of course.

Thank you in advance!

apologies, yes the previous script provided works 100%. I was going more into "next level" to see if I could control specific smart objects that share similar string names, but could target even more specificity, in this case, seperating the dogs and cats, i hope that makes sense.


I guess to simplify what I am trying to achieve is this: can I replaceof the 4 smart objects, just the smart objects that say "DOGS" to "PIGS", even if there had to be an extra or modified dialogue box to tell the script which animal to pull, while keeping the end text string the same.

Sample files (low resolution) or at least a screenshot of the layers panel and the properties panel for a selected layer would help others to help you.

Hopefully this explains it, simplified the request, basically looking to have a dialogue box open to replace linked smart object instances of the "like" layers. at once instead of having to repeat the process.
