What is the rm command?

The rm command in Linux is used to remove (delete) files and directories. Here are some key points about the rm command:

• Basic Usage: The simplest form is rm filename, which deletes the specified file.
• Multiple Files: You can delete multiple files at once by listing them, e.g., rm file1.txt file2.txt.
• Wildcards: You can use wildcards (like *) to delete multiple files that match a pattern, e.g., rm *.txt deletes all text files in the current directory.
• Directories: To remove a directory and its contents, you need to use the -r (recursive) option: rm -r directory_name.
• Permanent Deletion: Files deleted with rm are not moved to a trash or recycle bin; they are permanently removed.

Caution: Always double-check the files you are deleting, as this action cannot be undone.
