maildir2mbox - move mail from a mbox to a maildir

maildir2mbox [ -ks ] mbox maildir

mbox2maldir moves mail from a mbox-format file to an maildir-format directory.

maildir2mbox locks mbox to protect against simultaneous access by a mail reader. This locking system does not protect against simultaneous access by another mbox2maildir; you should run only one mbox2maildir at a time.

-k
Keep the mbox after conversion. Without this option, the mbox file is deleted

-s
Do not sleep after a successful conversion. Without this option, mbox2maildir will sleep for a second before exit
