From the safecat README:
|
|
|
|
safecat is an implementation of D. J. Bernstein's maildir algorithm.
|
|
It can be used to write mail messages to a qmail-style maildir, or to
|
|
write data to a "spool" directory reliably. There are no lockfiles with
|
|
safecat, and nothing is left to chance. If safecat returns a successful
|
|
exit status, then you can be (practically) 100% sure your data is
|
|
safely committed to disk. Further, if data is written to a directory
|
|
using safecat (or other implementations of the maildir algorithm),
|
|
then every file in that directory is guaranteed to be complete. If
|
|
safecat fails to write all of the data, there will be no file at all
|
|
in the destination directory.
|
|
|
|
Of course, you know that such a thing cannot be: between UNIX and
|
|
the different hardware options available, a 100% guarantee is not
|
|
possible. However, safecat takes every precaution possible in writing
|
|
your data.
