使用！源的gitconfig别名不起作用（zsh） [英] gitconfig aliasing using !source doesn't work (zsh)

问题描述

我有一个像这样的gitconfig：

I have a gitconfig like this:

[alias]
l = "!source ~/.githelpers && pretty_git_log"

当我运行它时，我得到这个：

When I run it I get this:

[desktop] git l
source ~/.githelpers && pretty_git_log: 1: source: not found
error: cannot run source ~/.githelpers && pretty_git_log: No such file or directory
fatal: While expanding alias 'l': 'source ~/.githelpers && pretty_git_log': No such file or directory

当我添加任何其他的shell内置函数来测试时，它们运行良好：

When I add any other shell builtins to test, they run fine:

[alias]
l = "!echo running from the builtin"

[desktop] git l
running from the builtin

任何想法为什么source命令不能从git中找到？我正在运行zsh，但更改为bash似乎没有什么区别：

Any idea why the source command can't be found from git? I am running zsh, but changing to bash didn't seem to make a difference:

[desktop] bash
[desktop] git l
source ~/.githelpers && pretty_git_log: 1: source: not found
error: cannot run source ~/.githelpers && pretty_git_log: No such file or directory
fatal: While expanding alias 'l': 'source ~/.githelpers && pretty_git_log': No such file or directory

推荐答案

从！< command> 构造试图通过该名称找到要运行的程序这一事实。有一个 / bin / echo 程序（它与你的shell内建的 echo 不同），但这是一个不同的故事），但不存在 / bin / source （或 / usr / bin 或其他任何地方）。根据 source 的性质，它不能是一个单独的程序。

The failure comes from the fact that the !<command> construct tries to find a program by that name to run. There is a /bin/echo program (which is different from your shell's built in echo, but that's a different story), but there is not a /bin/source (or /usr/bin or any other place). By nature of what source does, it cannot be a separate program.

试试这个：

[alias]
l = "!sh -c 'source ~/.githelpers && pretty_git_log'"

将 sh 更改为 bash （或其他）。

Change sh to bash (or whatever) as necessary.
