What is the `wc` command?

The wc command in Linux is a utility that stands for "word count." It is used to count the number of lines, words, and characters in text files. The command can be used with various options to specify what you want to count:

• -l: Counts the number of lines.
• -w: Counts the number of words.
• -m: Counts the number of characters.

For example, you can use the command as follows:

wc -l filename.txt   # Counts lines
wc -w filename.txt   # Counts words
wc -m filename.txt   # Counts characters

This command is useful for analyzing text files and understanding their content.
