Subject: Show pending jobs in HDB uucp
Message-ID: <[e-mail]>
Date: 29 Oct 90 21:58:30 GMT


  After a job comes in via uucp, and before it is run via uuxqt, it is
in a state I call "pending." When debugging a system, or just looking
around, I like to see what's there. Here's my program to do that. Also
useful when tuning the system to determine how often to run uuxqt from
cron.

#!/bin/sh
# shar:    Shell Archiver  (v1.29)
#
#    Run the following text with /bin/sh to create:
#      pending.1
#      Makefile
#      pending.c
#
sed 's/^X//' << 'SHAR_EOF' > pending.1 &&

X.SH NAME
Xpending \- list jobs pending from a remote site
X.SH SYNOPSIS
Xpending remotesite
X.SH DESCRIPTION
XThe \fBpending\fP command shows jobs received from a remote site which
Xhave not yet been processed by uuxqt. There are jobs which will be
Xexecuted locally at some future time.
X.SS INSTALLATION
XThis program will only run from the uucp user (unless you security is
X\fIvery\fP lax), but may be installed setuid to uucp.
X.SH EXAMPLES
X  $ pending maxxwell
X
X     Job             User            Input File      Task
X    crdgw1X0T9Q     root crdgw1     D.crdgw1b0T9S   rmail stugr02!bob
X.SH FILES
X/usr/spool/uucp/site/*
X.SH SEE ALSO
Xuustat
X.SH DIAGNOSTICS
XCan't get working dir - invalid site name of no directory for this site.
XCan't start ls - too many processes or /bin/ls missing.
XCan't open info file - sync error, uuxqt running, or access denied.
X.SH LIMITATIONS
XOnly works for HDB uucp.
