A high pass filter is a fitter that removes low frequency information form a singnal. Now there are many ways to implement a high pass filter, but photoshops high pass filter most likely is the result by subtracting the blurred image from the original (as mentioned by @filip).Simply all of image minus the low frequency is just the high frequency. A general purpose high-pass filter plugin. It shows up as Filters-Generic-High Pass Filter. You can select a blur radius that sets the size of detail to be passed by the filter, as well as an option to keep the source layer or replace it.

I have license of older version of Adobe Photoshop, I don't really need much, just a few things I use for touching up images. I'm not into amateur digital photography that much anymore and for development environment, I migrated to Linux.

I've been meddling with GIMP, I couldn't quite figure it out yet. For now I'm looking for something equivalent to High-pass, which I used to use in combination with 'Soft light' blending to selectively sharpen images.

Any editor with similar filters available for Ubuntu/Linux?

Since you already have Photoshop, you could try running it using Wine (assuming the filters you need are present in said version). And since it's an old version, you're less likely to run into problems.

Visit the official install page for Ubuntu to get started with the latest versions.

Check the Wine appdb page for Photoshop to see what results people have got running various Photoshop versions in Wine, and any necessary workarounds.
