在Linux上编写和测试的以下bash脚本在被调用时甚至无法在OS X上启动。
#!/bin/bash

function usage {

echo "<SOURCE_DIRECTORY> the directory where the this "
echo " directory resides (default is /usr/dis)"

sudo bash script.sh "arg1" "arg2"在具有bash 3.2的macOS上运行时，它将引发以下语法错误
'script.sh: line 7: syntax error near unexpected token `{
'script.sh: line 7: `function usage {
我对OS X相当陌生，也许我缺少一个陷阱。该脚本在Linux上运行良好...
谢谢
Linux和现代OS X期望行以LF（换行）字符结尾。如果您的行以CR + LF结尾，那么您将遇到问题。
其他一些一般性指针：
该function语法是非标准的。您应该使用所有POSIX兼容外壳程序都支持的标准语法：
改变：
function usage {
到：
usage() {
我怀疑一切都会好起来的。
顺便说一句，您应该引用所有参数扩展名（您错过了几个）。使用小写的变量名也被认为是一种好习惯，因为大写的变量名被shell使用，并且冒着与它们冲突的风险。
