Simple question but I just need to confirm the answer:

Many thanks

Just wondering if someone has a file open on client A for writing and it is locked, is that file still readable from client A or B?
Basically I'm just wanting to know if a file is opened already, can it still be opened for read only? (1 Reply)

getmail_mbox
getmail_mbox(1) User Commands getmail_mbox(1)
NAME
getmail_mbox - read a message from stdin and deliver to a named mboxrd-format mbox file with fcntl-style locking.
SYNOPSIS
getmail_mbox [OPTION] PATH
DESCRIPTION
Deliver a mail message from standard input, to the mboxrd-format mbox file named PATH. PATH must start with a dot or a slash and must not
end with a slash. fcntl-type locking is used; if your system requires another type of locking (such as flock or dotlock ), use an MDA con-
figured for that style of locking instead.
getmail_mbox uses the SENDER environment variable to construct a Return-Path: header field and the contents of the RECIPIENT environment
variable to construct a Delivered-To: header field at the top of the message. SENDER is also used in creating the mbox From_ line.
--verbose, -v
print a status message on success
