What does the 'rm' command do?

The 'rm' command in Linux is primarily used to remove files and directories from the filesystem. When executed, it will delete the specified file or directory, making it no longer accessible within the filesystem structure. This command does not move files to a temporary location (like a recycle bin), so once a file is deleted using 'rm', it is generally not recoverable through standard means.

The versatility of the 'rm' command also allows it to accept various options, enabling users to remove directories and their contents (using the '-r' option for recursive removal) or to force deletions without prompts (using the '-f' option).

Understanding the primary function of 'rm' as a deletion tool is crucial for managing files effectively in a Linux environment, as it highlights the importance of caution when using it to avoid accidental loss of data.
