I think they're all fine (if they claim some sort of stability) with the proviso that you're going to occasionally want to drop into bash or something to check something out before committing it to a script. (I assume you're talking about interactive use, not using them as the shebang line in your scripts. I wouldn't do that. But mainly just because then you need everyone to agree to install it, or to install it on your servers, etc.) > Fish is probably usable, but outside of fish I use fish, have for years, and I say the above to include it. Sometimes I'm not certain something works as I think it does (bash's myriad interpolation/variable manipulation techniques say) and so I switch shell to test it. It does have bugs and weirdness of course, especially the vi mode, but it's not going to .. idk, rm -rf / when I only told it to rm -rf ~/.cache/* or something.
