Deleting Files in Linux

Deleting files in Linux is a straightforward process that can be performed using the rm command. Here are the steps to follow:

• Using the rm command: The rm command is used to delete files and directories. To use it, simply type rm followed by the file or directory name you want to delete.
• Using the -i option: The -i option is used to prompt the user before deleting the file. This option allows the user to confirm whether they want to delete the file or not.
