The fish shell and executing programs from bash through `function`
提问by Athan Clark
I'm currently trying to run the
atom editorin the bashshell, from the fishshell. It's important that I run atomin bashbecause of how ide-haskell handles ghc-modpath resolution, and a few other standardization issues.
我目前正试图运行
原子编辑器中bash壳，从fish壳。由于 ide-haskell 如何处理路径解析以及其他一些标准化问题，我atom参与其中很重要。bashghc-mod
Here is how I was going at it:
这是我的处理方式：
#~/.config/fish/config.fish
function start-atom
bash $HOME/lib/atom/bin/Atom/atom $argv
end
However, when I try running start-atomfrom fish, I get the following error:
但是，当我尝试start-atom从运行时fish，出现以下错误：
/home/athan/lib/atom/bin/Atom/atom: /home/athan/lib/atom/bin/Atom/atom: cannot execute binary file
Even though I know this file is correct and executable. Any ideas? Thank you!
即使我知道这个文件是正确且可执行的。有任何想法吗？谢谢！

When you run bash file_nameit means you're trying to run file_nameas a bash script.
当您运行时，bash file_name这意味着您正在尝试file_name作为 bash 脚本运行。
Try this instead:
试试这个：
bash -c '$HOME/lib/atom/bin/Atom/atom "$@"' dummy $argv
The -cmeans "run this commandwith bash" instead of "run this script with bash".
的-c意思是“运行此命令在bash”，而不是“使用bash运行此脚本”。
As Charles pointed out in the comments, we have to do a bit of tweaking to pass the parameters to the command. We pass them to bashwhich will use them as positional parameters inside of the supplied command, hence the $@.
正如查尔斯在评论中指出的那样，我们必须做一些调整才能将参数传递给命令。我们将它们传递给它们bash，将它们用作所提供命令内的位置参数，因此$@.

should be: bash -c '$HOME/lib/atom/bin/Atom/atom "$@"' _ $argv
应该： bash -c '$HOME/lib/atom/bin/Atom/atom "$@"' _ $argv
The underscore will become bash's $0
下划线将成为 bash 的 $0
A demo:
一个演示：
$ function test_bash_args
bash -c 'printf "%s\n" "$@"' _ $argv
end
$ test_bash_args one two three
one
two
three
If you need that bash session to load your configs, make it a login shell.
如果您需要该 bash 会话来加载您的配置，请将其设为登录 shell。
So, bottom line: ~/.config/fish/functions/start-atom.fish
所以，底线： ~/.config/fish/functions/start-atom.fish
function start-atom
bash -l -c '$HOME/lib/atom/bin/Atom/atom "$@"' _ $argv
end
