file] [-s
sender] [user] |
The from
utility prints out the mail header lines from
the invoker's mailbox.
The following options are available:
-c
- Just print a count of messages and exit.
-f
file
- The supplied file is examined instead of the
invoker's mailbox. If the
-f
option is used, the
user argument should not be used. Read from standard
input if file name “-
” is
given.
-s
sender
- Only mail from addresses containing the supplied string are printed.
If user is given, the
user's mailbox is examined instead of the invoker's
own mailbox. (Privileges are required.)
MAIL
- If set, the location of the invoker's mailbox. Otherwise, the default in
/var/mail is used.
The from
command appeared in
3.0BSD.
