我试图循环两个变量序列,并使用R统计软件对它们进行处理,以获得相关结果。
我搞不懂为什么更大的循环(在mica_headers上)不会发生,而内部循环每次都会结束。

脚本中有一个错误,该错误回显了一个值$mica_header,该值将仅在下一次外部循环运行中被make调用所替代。这是因为第二个sed仅在make之后运行。它应该在内部循环之前被调用。这难道不会造成混乱吗?
此外,与其用一个参数值替换另一个参数值,不如创建一个r.src文件模板,其中包含要更改的参数的占位符。这样,我们可以确保参数的某些值不会与搜索模式冲突,并且拼写错误不会阻止替换。
下面是一个经过改进的脚本,代码相当简单。if test "$Test" = 1中的部分只是一个由Test=1激活的测试代码。对于此脚本,只需为r.scr创建一个名为r.scr.template的模板,并将占位符%%MicaHeader%%和%%CompilerOption%%替换为应替换的参数。对于第一个测试,参数列表较短。

r.src文件。make脚本是否确实使用了r.src.中的替换参数
