Which command is used to remove a file in Linux?

The command used to remove a file in Linux is "rm." This command is a standard utility in Unix-like operating systems that allows users to delete files from the filesystem. When executed with a file name as an argument, it permanently removes that file, freeing up the space it occupied on disk.

The "rm" command is known for its versatility; it can handle various options for recursive deletion, force deletion, and interactive prompts. For instance, using "rm -r" will allow users to first remove directories and their contents recursively, which is particularly useful when dealing with entire directory structures.

Many other operating systems utilize different commands for file deletion. For instance, "del" is commonly used in Windows command-line environments. The commands "erase" and "remove" might be intuitively thought to perform a similar function but are not recognized as standard commands for file deletion in Linux.

Understanding the distinctions between these commands and their operating systems is essential for effective file management within a Linux environment.
