如何使用Git别名启动Bash函数 [英] How to launch a Bash function using Git alias

问题描述

我想在〜/ .gitconfig中使用Git别名，以便它调用bash函数（如果已定义），否则调用常规的 git checkout 。

这是我设计的：

  cat〜/ .gitconfig 
 ... 
 [别名] 
 ... 
 co =！（compgen -A函数vxzExecuteGitCheckout> / dev / null&& vxzExecuteGitCheckout）|| git checkout 
  

问题是Git使用/ bin / sh（恰好是破折号），因为它是 bash ，所以它在 compgen 上倒刺

以任何方式确保Git使用 bash 执行此命令？

请注意， vxzExecuteGitCheckout（）是在尚不包含在〜/ .bashrc中的文件中定义的。

另一个问题是，如果我使用 git co -b param1 param2 ... ，上述别名定义是否会传递给 -b param1 param2 到 git checkout 如果找不到此Bash函数？

解决方案

明确使用 bash ：

  co =！bash -c'（compgen -A函数vxzExecuteGitCheckout> / dev / null&& vxzExecuteGitCheckout）|| git checkout'-
  

另一种可能性是编写带有正确shebang行<$ c的shell脚本$ c>＃！/ bin / bash 并为 alias.co 调用该脚本（请参阅问题如何将bash脚本直接嵌入git别名内）

I want to use a Git alias in ~/.gitconfig so that it calls a bash function, if it is defined, otherwise call the regular git checkout.

This is what I have devised:

cat ~/.gitconfig
...
[alias]
...
    co = !(compgen -A function vxzExecuteGitCheckout >/dev/null && vxzExecuteGitCheckout ) || git checkout

The problem is that Git uses /bin/sh (which happens to be dash in my case) and it barfs on compgen since it is a bash builtin.

Any way making sure that Git uses bash to execute this command?

Note that vxzExecuteGitCheckout() is defined in a file which is not included in ~/.bashrc, yet.

Another question is, if I were to use git co -b param1 param2 ..., would the above alias definition pass on the -b param1 param2 to git checkout if this Bash function is not found?

解决方案

use bash explicitely:

co = !bash -c '( compgen -A function vxzExecuteGitCheckout >/dev/null && vxzExecuteGitCheckout ) || git checkout' -

another possibility would be to write a shell script with the correct shebang line #!/bin/bash and call that script for alias.co (see the question How to embed bash script directly inside a git alias)
