Fish just uses (cmd), no $.
- e12e 8y agoAh, which I guess is why no subshell support?
- cormacrelf 8y agoThere are other ways to do subshells than using the same syntax, just that the Fish developers never did it, maybe because it's not requested enough. I think it's still the most annoying thing about Fish, and the most convincing reason to switch away again. I frequently drop into bash to do (cd subdirectory && command --that might.fail) && run --command-in-original-dir --only-if-subshell-succeeded ... and expect to still be in the original dir when it's done. Any solution in Fish using "&& cd -" at the end of a block AFTER a maybe-failing command is just wrong, and there seriously isn't any way except saving and restoring $PWD every time you want subshell functionality, or using "; cd -" and manually saving the $status, which is equally as frustrating. There are some non-syntactic suggestions in https://github.com/fish-shell/fish-shell/issues/1439 https://github.com/fish-shell/fish-shell/issues/1439
