Linux 查找和替换(有条件)

Question

我有一个非常具体的要求，我发现很难做到，我需要查找并替换文件中的某些行，但问题是文本不同，唯一的好处是它们都有一个 .[扩展名]

例如:

30/07/2012  14:46            17,232 training program.DOCX.ddkhqvh
08/03/2011  20:57            31,664 nutritional program.XLS.ddkhqvh

需要:

F:/home/training program.DOCX.ddkhqvh
F:/home/nutritional program.XLS.ddkhqvh

我尝试使用 awk，但我很费劲。

Answer 1

这个怎么样:

$ awk '/^[0-9]+\/[0-9]+\/[0-9]+/ { sub(/^[^ ]+ +[^ ]+ +[^ ]+ +/,"F:/home/"); print; }' <file.txt

这仅选取文件中具有初始日期的行，因此仅修改文件中列出的文件名。
