Alternatives

The rm command is a powerful tool for deleting files and directories on a remote server. However, there are a number of alternatives to the rm command that can be used for the same purpose. These alternatives can be useful in certain situations, such as when the rm command is not available or when you need more control over the deletion process.

One of the most popular alternatives to the rm command is the unlink command. The unlink command is similar to the rm command, but it does not recursively delete directories. This can be useful if you want to delete a file without deleting its parent directory.

Another alternative to the rm command is the find command. The find command can be used to find files and directories that meet certain criteria. Once you have found the files and directories that you want to delete, you can use the -delete option to delete them.
