ack: Count the total number of matches found.

$ ack --count --no-filename "${search_pattern}"

try on your machine

This command uses the ack tool to count the number of occurrences of a specific search pattern in one or more files within a directory.

Here is a breakdown of the command:

ack: Invokes the ack command-line tool, which is a tool similar to grep but optimized for code searching.
--count: Specifies that we want to count the occurrences of the search pattern instead of displaying the actual lines.
--no-filename: Suppresses the display of filenames in the output. It ensures that only the count is shown, without the corresponding file names.
"${search_pattern}": The search pattern to look for. This is typically a regular expression or a plain text string enclosed in double quotes.

When this command is executed, ack will search for the specified search_pattern in the files and directories within the current working directory, and it will output the total count of occurrences that match the pattern across all the files.
