NAME

lockspool - lock user's system mailbox  

SYNOPSIS

lockspool [username ]  

DESCRIPTION

lockspool is useful for a client mail program to attain proper locking. lockspool obtains a username.lock for the calling user and retains it until stdin is closed or a signal like SIGINT SIGTERM or SIGHUP is received. Additionally, the superuser may specify the name of a user in order to lock a different mailbox.

If lockspool is able to create the lock file, ``1'' is written to stdout, otherwise ``0'' is written and an error message is written to stderr. lockspool will try up to 10 times to get the lock (sleeping for a short period in between tries).

The lockspool utility exits 0 on success, and 1 if an error occurs.  

FILES

/var/mail/username.lock
user's mail lock file
