The command "wc -w ${filename}" is used to count the number of words in a specified file.

Here's a breakdown of the command:

• "wc" stands for "word count" and is a command in Unix-like operating systems that can count the number of lines, words, and bytes in a file.
• "-w" is an option or flag accompanying the "wc" command, specifically indicating that we want to count the number of words.
• "${filename}" is a placeholder for the actual filename you want to check. You need to replace "${filename}" with the actual name of the file you want to analyze.

To run this command, open your terminal, navigate to the directory where the file is located (or provide the full path to the file), and replace "${filename}" with the name of the file you want to analyze.
