The command "rgrep --fixed-strings "${exact_string}"" is used to search for a specific string in files within a directory and its subdirectories.

Here's a breakdown of the command:

• "rgrep" stands for "recursive grep" and it is a command-line tool used for searching text patterns in files.

• "--fixed-strings" (or simply "-F") is an option that tells rgrep to treat the specified search pattern as a fixed string, rather than interpreting it as a regular expression. This means that special characters and regex metacharacters in the search pattern will be treated as literal characters.

• "${exact_string}" is a placeholder for the actual string you want to search for. To use this command, you should replace "${exact_string}" with the specific string you want to find. For example, if you want to search for the word "hello", the command would become "rgrep --fixed-strings "hello"".

By running this command, rgrep will search for the exact string within the specified directory and display the matching lines along with the respective file names. It will also search within subdirectories recursively, allowing you to find occurrences of the string in multiple files located in different subfolders.
