我之前找到了一个 Bash 脚本片段,用于将字符串回显到 stderr:
echoerr() { echo "$@" 1>&2; }
echoerr hello world

这保留在我的剪贴板中,当我想编辑一个文件(使用 VIM)时,我不小心再次粘贴了这个片段而不是文件名:
vim echoerr() { echo "$@" 1>&2; }
echoerr hello world

它似乎已重新分配echoerr
给vim
:
$ where vim
vim () {
echo "$@" 1>&2;
}
/usr/bin/vim

此外,尝试使用 VIM 打开文件现在只会回显文件名:
vim path/to/some-file

印刷:
path/to/some-file

发生了什么?(我在 tmux 中运行 zsh)
因为zsh
允许您定义具有多个名称的函数。来自man zshmisc
:
function word ... [ () ] [ term ] { list }
word ... () [ term ] { list }
word ... () [ term ] command
where term is one or more newline or ;. Define a function which
is referenced by any one of word. Normally, only one word is
provided; multiple words are usually only useful for setting
traps. The body of the function is the list between the { and
}. See the section `Functions'.
