BASH函数中的returnand exit语句与退出代码有什么区别？

我想在每次git推送之前运行一个单元测试,如果测试失败,取消推送,但我甚至找不到预推钩,只有pre-commit和pre-rebase.

我想在Bash脚本中引发错误,消息"Test cases Failed !!!".在Bash中如何做到这一点？

例如:

if [ condition ]; then
    raise error "Test cases failed !!!"
fi

看看这个小脚本：

#!/bin/bash

function do_something() {(
    set -e

    mkdir "/opt/some_folder"                                     # <== returns 1 -> abort?
    echo "mkdir returned $?"                                     # <== sets $0 to 0 again

    rsync $( readlink -f "${BASH_SOURCE[0]}" ) /opt/some_folder/ # <== returns 23 -> abort?
    echo "rsync returned $?"                                     # <== sets $0 to 0 again
)}


# here  every command inside `do_something` will be executed - regardless of errors
echo "run do_something in if-context.."
if ! do_something ; then
  echo "running do_something did not work" …
