It used to work fine, but in my latest build from git as of 2019-11-04 (4th november) it does not. Maybe it stopped to work earlier, I don't know, I was reworking my init file, so I didn't had it in for like a month or so, anyway, when I test it today I don't get the 'alias' command to work at all. It works from ansi-term, but not interactively or from an elisp script. I get message that shell command succeeds without any output. The line (shell-command "alias" "bash-aliases" "bash-errors") is part of a little script I posted on Emacs Wiki earlier this year https://www.emacswiki.org/emacs/EshellAlias. Is it a bug or do I something wrong? I am sorry, I am not an expert on Emacs, so I am a bit unsure.

I don't see how this could have worked earlier or how it could work now. One work-around, if you really need this, would be to put the relevant aliases in a new file, say "~/.bash_aliases", and then running: (setenv "BASH_ENV" "~/.bash_aliases") (shell-command "alias") This utilizes the fact that the file pointed to by the BASH_ENV environment variable will always be sourced. But be aware that this may cause problems, depending on the contents of your "~/.bash_aliases" file. For more information on this, see the bash man page section "INVOCATION". In other words, this is all working as expected, and I'm closing this as notabug. Best regards, Stefan Kangas ^ permalink raw reply [flat|nested] 6+ messages in thread

I have looked at SX-article, and I do understand that bashr is not sourced in non-interactive shells since before, however, I do have my Shell command set to use ”-ic” flags. It also used to work earlier; when I wrote that function and posted on wiki, with same Shell flags. I don’t know how or why it worked earlier if it shouldn’t work though 😊. Even more confusing, it works fine on MS Windows (msys2 distro of *nix Tools), Without even using ”-ic” flag. I use same bashrc as I do under my GNU/Linux, but I attribute that to (probable) msys2 quirks. *nix gods are not smiling at me?

When I try setting that, `M-x shell-command RET alias RET' gives me my full list of aliases. I'm not sure why you're seeing this, but it sounds like there may be some other variable at play here.
