'echo "<somewhat string>" >> oracle_file' will corrupt the file, but oracle 
will detect it only when it tries to read/write to that block(s) at the end 
of the file. Rman, as far as I know, will detect it immediately too, except 
for some spacial cases (block change tracking enabled with certain type of 
backup).
