If that name was the last link to a file and no processes have the file open the file is deleted and the space it was using is made available for reuse. If the name was the last link to a file but any processes still have the file open the file will remain in existence until the last file descriptor referring to it is closed. If the name referred to a symbolic link the link is removed. -- end quote -- So, if there's a symlink, you can expect the symlink to be removed, but the file it linked to to be untouched. Even if it's a hard link, the file will still exist unless the other link to it gets removed.
