Q: What happens when file is deleted in Linux?

> 1. The directory entry linking the filename to its Inode number is removed. 2. The inode's hard link count is decremented by 1. 3. If the link count reaches 0 and no running process holds an open file descriptor to the file, the block addresses are marked as free in the filesystem allocation bitmap. 4. The actual data remains on disk until overwritten by new file writes.
