i meant to ask whether the terminal under Waydroid can use FISH or whether it can load under Waydroid separately?

@effiltgvsmozmail-com Android is built against bionic libc, if you want fish shell you need a bionic build of it and you can then execute that from Android

My sophistication in the libc build is obviously not at the level that you note. I am a more casual user in an area where I constantly learn. I am hoping to increase usage of the medium and in the process I am playing a good deal of a catch up to the specific issues which are of multiple different natures of complexity.
Thank you for the feedback. I can see if any such as myself are interested in making a bionic build of libc while I tool up my skills in such areas.
