findstr:tldr:1da09

The command findstr is a command-line utility in Windows that is used to search for specific strings of text in files.

In this specific command:

1. findstr is the command itself.
2. /c:"${query}" specifies the search string or pattern. The ${query} is typically a placeholder for the actual string you want to search for. The /c switch is used to define the literal string to be searched.
3. *.txt represents the file(s) on which the search will be performed. In this case, it searches for files with the .txt extension. The asterisk (*) is a wildcard that matches any characters before the extension.

So overall, the command searches for the specific string or pattern (represented by ${query}) within all the .txt files in the current directory.
