NAME
faxalter - alter parameters of a HylaFAX job queued for transmission
SYNOPSIS
faxalter [ options ] id...
DESCRIPTION
faxalter changes the state of one or more HylaFAX jobs that are queued
for transmission. Numerous parameters can be altered; see the options
below.
An id is a number that identifies a job that has been submitted to
HylaFAX; these numbers are printed by sendfax(1) when jobs are queued
for transmission and can also be displayed with faxstat(1).
Unprivileged users can alter the parameters of jobs that they own;
clients with administrative privileges on a server can manipulate any
job (see the -A option below). The user may be specified by the
FAXUSER environment variable. By default, faxalter contacts the
facsimile server on the host specified in the FAXSERVER environment
variable; but consult the -h option for more information.
OPTIONS
-a time Specify a new time to send a job. The syntax for specifying
a time is the same as used by sendfax(1) (and at(1)).
-d destination
Change the destination number to destination.
-h host Force the server to be contacted on a specific host. The
host may be either a symbolic name or a network address. If
no -h option is supplied, faxalter uses the FAXSERVER
environment variable to identify the HylaFAX server to
contact. If this variable is not set, then faxalter checks
for a setting in the configuration files (first in the per-
user file and then in the system-wide file). If all of the
above fails, then faxalter attempts to contact a server on
the machine where it is run.
-A Use administrative privileges; faxalter will prompt for the
password to set administrative privileges.
-k time Specify a new time to kill a job; the syntax is the same as
used for the -a option.
-m modem Assign/reassign the jobs to the specified modem. Specifying
``any'' for modem causes the jobs to be scheduled for any
available modem.
-p The jobs should be pushed; that is, they should be requeued
with a time-to-send as the current time (this is equivalent
to ``-a now'').
-P pri Set the scheduling priority for the specified jobs. The
priority is an integer value in the range 0-255; lower values
give a job higher priority. The default scheduling priority
for a job is 127 and priorities are recalculated after each
attempt to process a job.
-r Resubmits a job. This will duplicate any job that is in
either the send queue or in the done queue. When
resubmitting jobs that are past their killtime the -k option
should also be used to specify a new time to kill the job.
-t tries Set the maximum number of times the server should call the
remote fax machine.
-n scheme Select a notification scheme to use for the specified jobs.
Possible schemes are: ``none'' for no notification (default),
``when done'' for notification when the job is completed,
``when requeued'' for notification when the job is requeued
after a failed transmission attempt. The -Q, -D, and -R
options are shorthand for these notification schemes,
respectively. One can also leave off ``when'' when using the
-n option; e.g., ``done'' instead of ``when done''.
-v Trace the protocol exchanges between faxalter and the remote
hfaxd process. Tracing information is written to the
standard output.
-Z range Change the page range to be faxed to range
CONFIGURATION PARAMETERS
faxalter reads configuration information from the file
/usr/local/lib/fax/hyla.conf and then from the file ~/.hylarc.
Configuration files follow the conventions described in
hylafax-client(1). The following configuration parameters are
recognized:
Tag Type Default Description
Host string localhost host to contact for service
PassiveMode boolean false whether or not to use passive mode
Port integer 4559 port to use in contacting server
Protocol string tcp protocol to use in contacting server
Verbose boolean No whether or not to enable protocol tracing
The configuration parameters are explained below:
Host The host to contact for service. (Equivalent to the -h
option.)
PassiveMode
Whether or not to use passive mode in communication with the
server.
Port The network port to contact for service. (Equivalent to the
-h option.)
Protocol The name of the communication protocol to use when contacting
a server. (Equivalent to the FAXSERVICE environment
variable.)
Verbose Control protocol tracing. (Equivalent to the -v option.)
NOTES
Setting a job's killtime without also setting the time to send may
cause the wrong value for the killtime to be sent. This is because the
killtime is calculated as the difference in time between the killtime
and time to send: and if the time to send is not specified, then
faxalter uses the current time instead of querying the server for the
job's time to send.
faxalter suspends a job before attempting to alter its state. If a job
is active when a suspend request is made there may be a delay while
waiting for the job to enter a consistent state where it can be
suspended. If faxalter is interrupted during this time then jobs may
be left suspended.
faxalter requeues the job. This means that the job will end up at the
bottom of the queue for the job's priority. Thus, when queues are
heavy an adjustment of the job's killtime may need to be considered
when altering any other parameter.
faxalter only understands how to alter a subset of the available job
parameters; there are many more client-controllable parameters that can
only be modified by communicating directly with the server using the
underlying protocol.
The continued use of the at(1)-style notation for specifying times is
questionable (it was done for backwards compatibility).
