这就像在脚本run2.sh中放入一个运行函数一样。 您可以在run中使用退出代码，同时在bash tty中生成run2.sh文件。 如果给运行函数退出脚本的权力，并给run2.sh 它是退出终结者的力量。 然后因为运行函数有能力退出你的终止器。

    #! /bin/sh
    # use . run2.sh

    run()
    {
        echo "this is run"
        #return 0
        exit 0
    }

    echo "this is begin"
    run
    echo "this is end"

不管怎样，我同意卡兹的观点，这是一个设计问题。

我认为这是因为您在源模式下运行它 带点的

. myscript.sh

你应该在子shell中运行它:

/full/path/to/script/myscript.sh

“源”http://ss64.com/bash/source.html

还要确保返回时带有预期的返回值。否则，如果你在遇到退出时使用exit，它将从你的base shell退出，因为source没有创建另一个进程(实例)。

是的,你可以用return代替exit。它的主要目的是从shell函数返回，但如果在source-d脚本中使用它，它将从该脚本返回。

如Bash参考手册§4.1“Bourne Shell Builtins”所述:

return [n] Cause a shell function to exit with the return value n. If n is not supplied, the return value is the exit status of the last command executed in the function. This may also be used to terminate execution of a script being executed with the . (or source) builtin, returning either n or the exit status of the last command executed within the script as the exit status of the script. Any command associated with the RETURN trap is executed before execution resumes after the function or script. The return status is non-zero if return is used outside a function and not during the execution of a script by . or source.

    run()
    {
        echo "this is run"
        #return 0
        exit 0
    }

    echo "this is begin"
    run
    echo "this is end"

不管怎样，我同意卡兹的观点，这是一个设计问题。

我找不到解决方案，所以对于那些想要离开嵌套脚本而不离开终端窗口的人:

# this is just script which goes to directory if path satisfies regex
wpr(){
    leave=false
    pwd=$(pwd)
    if [[ "$pwd" =~ ddev.*web ]]; then
        # echo "your in wordpress instalation"
        wpDir=$(echo "$pwd" | grep -o  '.*\/web')
        cd $wpDir
        return
    fi
    echo 'please be in wordpress directory'
    # to leave from outside the scope
    leave=true
    return
}

wpt(){
    # nested function which returns $leave variable
    wpr
    
    # interupts the script if $leave is true
    if $leave; then
        return;
    fi
    echo 'here is the rest of the script, executes if leave is not defined'
}
