findstr:tldr:2c8fb

The command "findstr /n "${query}" " is used in command-line environments such as Windows Command Prompt to search for a specific string (${query}) within a set of files. Here's a breakdown of the command: - "findstr" is a command-line tool used to search for text patterns in files. - "/n" is an option for the findstr command that causes it to display line numbers along with the matching lines. - "${query}" represents the string you want to search for within the files. - "" is a wildcard character that is used to specify the files or filenames to search within. In this case, it means to search within all files in the current directory. So, when you run the command, it will search for the string specified in ${query} within all files present in the current directory and display the matching lines along with their line numbers.
