是的，该return语句只能用于从 shell 函数或点脚本（使用.(dot) 或source在支持 别名的 shell 中获取的脚本.）返回退出状态。 Shell 函数和点脚本在这方面非常相似。
您显示的代码包含一个return语句作为其最后一个可执行语句，如果您将脚本作为普通脚本运行，这可能是引发错误的原因。
您的脚本很可能应该执行为
. ./script.sh
而不是作为
./script.sh
或者那个其他脚本应该做到这一点（这是未知的）。如果您确实使用点命令（或source例如）运行脚本，请注意，您将在脚本执行结束后bash留在其中（因为这是脚本在退出时更改工作目录的位置）。/ERQ/100/DM/SCRIPTS
另请注意，该脚本使用一些奇怪的代码来执行普通的操作。例如，要测试是否$ARCHIVE_PATH已定义
VARCHECK=`echo $ARCHIVE_PATH | wc -w`
if [ $VARCHECK = "0" ]
此测试不会测试它是否未定义，而是测试它是否为空（或仅包含 中的字符$IFS）。事实上，一半以上的脚本都由验证配置设置的语句占用。
相反，人们可以使用
if [ "${ARCHIVE_PATH-is unset}" = "is unset" ]
或者，在bash，
if [ ! -v ARCHIVE_PATH ]
或者，如果您只想测试空值，
if [ -z "$ARCHIVE_PATH" ]
该脚本还在ls多个地方使用来获取文件列表，这不太理想。
