For the unaware, Time Machine is the macOS built-in backup system. Once configured, it takes frequent filesystem snapshots and syncs them to a connected storage device. If the file being removed is included by those backups, and existed long enough to be in a snapshot, then you can restore it from the TM backup. Neither of those criteria are guaranteed, as when working with files in a Terminal or bash script you can easily create and remove files with names and/or locations that exempt them.
