Doscommand findstr and FC

In the process of analyzing or writing code, you often need to search for strings in the file or compare the two files. Common commands in Linux are grep and diff. Windows files have good open-source tools, such as winmerge. Searching for strings in files is unclear whether there are good open-source tools. Recently, we found that Windows has a doscommand to meet your needs.

Findstr: Search for strings in the file.
