findstr to find multiple strings in multiple files

As discussed on this blog in the past, the Windows command findstr can be used to perform complicated searches through multiple files, including regular expression searches. Here's a quick demo of how findstr can be used to search for multiple search terms in multiple files.

Compose a batch file with this code:

@echo off

for /F %%i in (searchlist.txt) do ( echo Files containing %%i findstr /C:%%i /S *.txt )

[Enter this in a text file and then save it with the extension 'bat'. ]

'searchlist.txt' refers to a file listing the strings you want to search for. Each string needs to be on a separate line.

The end of the code [*.txt] specifies that only .txt files should be searched.

The result shows the hits in context for each file, one search term at a time:

Thanks to Srini for the code.
