运行 Shell 脚本时未找到 Mac 终端 Foreach 命令

Question

我正在尝试在终端中运行一个脚本，但我收到了错误消息，即未找到 foreach 命令。在过去的 6 个小时里，我一直试图在网上找到答案，但我似乎找不到任何东西。你能告诉我为什么这是输出'line 20: foreach: command not found'吗？

脚本在这里：

Answer 1

失败的原因是 csh 具有其他 shell 所没有的 foreach 循环。 因此，如果您尝试通过任何其他 shell 执行脚本，它将失败。

由于您已经拥有#!/bin/csh，因此您可以使用./scriptname 执行脚本，但如果您打算在其他shell 中执行它------

用下面的代码替换每一行

for sub in $(echo "all the strings seperated by a space")
 do 

 \# rest of your script inside for should come here

done         #done is replacing end in your case

如果您不能使用echo "string SEPERATED by spaces"，那么您可以将cut 与您拥有的分隔符一起使用。

我无法确定您在 foreach 语句中使用的分隔符。
