PROGRAM:
NAME
mutt_dotlock - Lock mail spool files.
SYNOPSIS
mutt_dotlock [-t|-f|-u|-d] [-p] [-r retries] file
DESCRIPTION
mutt_dotlock implements the traditional mail spool file locking method: To lock file, a
file named file.lock is created. The program operates with group mail privileges if
necessary.
OPTIONS
-t Just try. mutt_dotlock won't actually lock a file, but inform the invoking process
if it's at all possible to lock file.
-f Force the lock. If another process holds a lock on file longer than a certain
amount of time, mutt_dotlock will break that lock by removing the lockfile.
-u Unlock. mutt_dotlock will remove file.lock.
-d Delete. mutt_dotlock will lock file, remove it if it has length 0, and afterwards
remove file.lock.
-p Use privileges. If given this option, mutt_dotlock will operate with group mail
privileges when creating and deleting lock files.
-r retries
This command line option tells mutt_dotlock to try locking retries times before
giving up or (if invoked with the -f command line option) break a lock. The
default value is 5. mutt_dotlock waits one second between successive locking
attempts.
