rg: Search for a regular expression only in a subset of directories.

$ rg ${regular_expression} ${set_of_subdirs}

try on your machine

The command "rg ${regular_expression} ${set_of_subdirs}" is used to search for a specific regular expression (pattern) within a set of subdirectories.

Let's break down the command:

"rg" stands for "ripgrep," which is a command-line tool used for searching files and directories quickly. It is similar to the commonly-used "grep" command but with better performance.
"${regular_expression}" represents the regular expression or pattern that you want to search for. Regular expressions are a powerful way to describe complex search patterns. For example, if you want to find all lines that contain the word "example" in your set of subdirectories, you might use the regular expression "example".
"${set_of_subdirs}" refers to the set of subdirectories in which you want to search. It can be a single directory path, multiple directory paths separated by a space, or even the wildcard character "*" to indicate all subdirectories in the current location.

When executing the command, "rg" will search for matches of the provided regular expression within the specified set of subdirectories and display the results in the terminal. The output typically includes the file name, line number, and the line itself where the match was found.
