Subject:  v18i001:  Display mail queue and "from" output
Newsgroups: comp.sources.unix
Approved: [e-mail]

Submitted-by: Kevin Sweet <[e-mail]>
Posting-number: Volume 18, Issue 2
Archive-name: mq

Replacements for mailq and from:

mq -    selectively display the mail queue.
    options exist to list mail from or to a particular site, list
    mail exclusive of a particular site, and list mail without the
    truncation of long pathnames.

from -    makes `from' output look somewhat like `Mail' "header" output
    in that it prints out a minimalistic pathname to the sender and
    the subject line. It catches subject titles that `Mail' some-
    times misses like news articles saved in mbox format.

I have listed the machine/OS combinations (BSD/SysV) that I have
successfully compiled and run the programs in the Makefile.

One comment, however.  No checking is done with respect to what other
programs (or users) are doing to the mail queue files and mailboxes.
(I have received segmentation faults _occasionally_ when, I assume,
 `sendmail' is deleting a file that `mq' wants to read. I'm a scientific
 programmer that did this for "fun" and don't know what to do about this
 situation. `From' seems to be pretty resilient, though.)

XX[\fB\-f\fR]
XX[\fBfile\fR]
XX[\fB\-d\fR]
XX[\fB\-w\fR]
XX[\fB\-s\fR [sender]]

XX.SH DESCRIPTION
XX.I From
XXlists an abbreviated name for the sender of each letter in the
XXspecified mail file
XX.KS file
XX(which
XX.UL may
XXbe preceded or prepended on the command line by \fB\-f\fR)
XXalong with the subject of the letter so that both sets of information
XXcan fit into 80 columns of standard output.
XX.Sh Options
XXWith no options, \fIfrom\fR lists the mail in the user's system mailbox.
XX.TP 1i
XX.B \-f
XXIf
XX.KS file
XXis not specified, then mail in the file \fImbox\fR in
XXthe user's home directory is listed (see ENVIRONMENT section for
XXfurther details).
XXOtherwise, mail in the mailbox
XX.I file
XXis listed.
XX.TP
XX.B \-h
XXPrint the \fIfrom\fR syntax.
XX.TP
XX.B \-d
XXThe complete return path and the date received are displayed.
XX(This duplicates \fI/usr/ucb/from\fR.)
XX.TP
XX.B \-w
XXThe \fB\-w\fR option is similar to that for \fIps\fR on BSD systems.
XXSelecting \fB\-w\fR displays each entry in long form (in this case,
XXa minimalist sender's address and the full subject);
XXwhereas, \fB\-ww\fR displays each entry in unabridged form (i.e., the
XXfull subject and the complete return path for the sender are listed).
XX.TP
XX.BR \-s " sender"
XXOnly mail from \fIsender\fR is listed. \fISender\fR defaults to
XX$LOGNAME on System V and to $USER on BSD systems.
XX.TP
XX.BR \-u " user"
XXMail in \fIuser\fR's system mailbox is listed.
XX.SH ENVIRONMENT
XX.I From
XXuses the following environment variables:
XX.TP 1.375i
XXHOME
XXThe user's home (default login) directory.
XX.TP
XXUSER/LOGNAME
XXThe user's user (login) name.
XX.PP
XXIf the environment variable MAILRC is set,
XX.I from
XXwill check the mail startup file specified by $MAILRC instead of
XX\fI$HOME/.mailrc\fR.
XXIf the environment variable MBOX is set,
XX.I from
XXwill recognize the default mailbox specified by $MBOX rather than
XXthat specified in the mail startup file
XXor
XX\fI$HOME/mbox\fR.
