【问题描述】:
我是 bash 脚本的新手。我想逐行读取包含表格的文件。在每一行,我想将值分配给变量。这基本上是我的代码格式:
#!/bin/bash
while IFS= read -r line; do
echo $a $b $c $d
#if statements…
done < test.txt
我收到此错误:“While 循环错误:意外标记 `done' 附近的语法错误”
知道我的代码有什么问题吗?我尝试查看与同一错误相关的其他几个问题,但我无法修复我的代码。感谢您的帮助!
编辑:这是整个代码。它可能还有其他错误(我真的是初学者),但我希望它有所帮助。

如果我有任何澄清,请告诉我。
【问题讨论】:
-
发布循环的内容。你可能有一些未闭合的嵌套结构或不平衡的括号或其他东西。
-
我在您发布的代码中没有发现任何错误。创建一个重现问题的最小示例,并将该确切代码复制并粘贴到您的问题中。 (您可能会在缩小测试用例范围的同时自己解决问题;在这种情况下,您可以删除问题或发布答案,具体取决于它是否对其他人有用。)
-
您发布的代码显然可以按原样运行
-
我编辑了我的帖子并添加了整个代码,也许它会有所帮助。我的其余代码可能会令人困惑,如果我能澄清任何事情,请告诉我!
-
基思所说的:创建一个最小的例子。可能是通过删除块,并在每次删除块后检查错误是否仍然存在。 (此时我的假设是您没有正确计算您的 if/fi。
