mail.local reads the standard input up to an end-of-file and appends it to each
user's mail file. The
user must be a valid user name.
The options are as follows:
-f from
Specify the sender's name.
-l
Request that username.lock files be used for locking.
Individual mail messages in the mailbox are delimited by an empty line followed by a line beginning with the string ``From ''. A line containing the string ``From '', the sender's name and a time stamp is prepended to each delivered mail message. A blank line is appended to each message. A greater-than character (``>'') is prepended to any line in the message which could be mistaken for a ``From '' delimiter line.
If the [
-l] flag is specified mailbox locking is done with
username.lock files. Otherwise, the mailbox is exclusively locked with
flock(2) while mail is appended.
If the ``biff'' service is returned by
getservbyname(3), the biff server is notified of delivered mail.
The
mail.local utility exits 0 on success, and >0 if an error occurs.
