What command displays the number of lines, words, and characters in files?

The command that displays the number of lines, words, and characters in files is "wc," which stands for "word count." This command is commonly used in Linux and Unix-based systems to analyze text files. By default, when you run "wc" with a filename as an argument, it will return three numbers: the first representing the line count, the second representing the word count, and the third representing the character count of the file.

For instance, when executing wc filename.txt, the output might look something like this:

10  50  300 filename.txt

This indicates that there are 10 lines, 50 words, and 300 characters in the file named "filename.txt." The versatility of "wc" is further enhanced by options that allow users to focus only on specific counts—such as using -l for line count, -w for word count, or -c for character count—making it a valuable tool for processing and analyzing text data in scripting and command-line operations.
