[erlang-questions] Read and delete file
Sun Dec 13 07:40:41 CET 2009
May I ask why you need to remove the first line?
In some cases I've been involved in something similar we have done one
of the following (AFAIR):
* Don't delete the line, move an index. If need for failover handling
then make the index value persistent
* Write to a "rest" file meaning that assuming you are reading line by
line (and not deleting) you can (when finished) write the rest of the
file to another file, close the one you have opened and then overwrite
it with the temporary one.
