在Bash 脚本中,return和exit都可以用来结束函数的执行,但它们之间存在一些重要的区别: 基础概念 return:用于从函数中返回一个值,并结束该函数的执行。它只会影响当前函数的执行流程,不会影响脚本的其他部分。 exit:用于终止整个脚本的执行。当调用exit时,脚本会立即停止执行,所有的后续命令都不会被执行。 相关优势 r...

Return is a bash builtin function that causes to update the exit status specified by n. Return is intended to be used only for signaling errors, not for returning the results of function. If used: inside a function. Return value specified by n.
我对别人写的以下bash命令行感到困惑: return -1 || exit -1 这是什么意思?我理解||构造意味着如果第一部分(在这种情况下,return -1)失败(即返回非零代码),那么第二部分(exit -1)将得到执行。另外奇怪的是,这个语句不是任何函数的一部分,而是在脚本的主体中。 感谢有人能向我解释这个。 - Hai Vu1...
