old print job removal

Craig A. Sharp — Mon, 04 Dec 2006 12:03:03 GMT

I need to remove print jobs older than 5 days. I would like to do this in perl if possible. Does anyone have any examples of how to do this. We are constantly having to remove jobs that are stale off our print queues manually. With ~1000 printers, this is quite a task and needs to be automated.

I am not proficient in perl, hence I will not even attempt to solve your problem, but as a hint,

jobline=`lpstat -o | grep priority`
jobid=`echo $jobline|awk {'print $1'}
day=`echo $jobline|awk {'print $6'}
month=`echo $jobline|awk {'print $5'}
jobtime=`echo $jobline|awk {'print $7'}

usning these variables and using the caljd.sh script, provided by Clay Stephenson (go to http://mirrors.develooper.com/hpux/ and look for words "Date Hammer" to get either shell or perl versions), you can calculate the time past since the request has been submitted and make a decision to delete it or not.

Hope this helps.

Not Perl - but sh:

# cat /usr/local/bin/lpqpurge
#!/bin/sh
#
# script to cancel jobs older then the current month
# run say on the 21st of each month
# gwild

# get the current month

M=`date +%b`

# cancel any jobs older then current month
# lpstat -o returns the following fields
# GB01-7606 ipradm priority 3 Apr 22 04:05 on GB01
# so, compare field 5 to the current month

for JOB in `lpstat -o |grep -v bytes|awk '$5ne"$M"{print $1}'`
do
cancel $JOB
done

# could have been done on 1 line like so:
# lpstat -o |grep -v bytes|awk '$5ne"`date +%b`"{print $1}'|xargs cancel
# but if there are no jobs older then current month - then cancel outputs error

Hi Craig:

Firstly, you need to 'cancel' those jobs that you find are candidates. In this way, you keep the lp subsystem "happy".

This Perl script lists the jobs that exist:

#/usr/bin/perl
use strict;
use warnings;
my @requests;
my $request;
@requests=grep{/priority/} `lpstat`;
for $request (@requests) {
print $request;
}

From here, you can enhance the script to snip the request-ID and, using the Perl 'Date::Calc' module's 'Delta_Days' function, calculate the age in days of the request. If it meets your criteria, make a 'cancel' request by calling 'system()'.

Regards!

Hi (again) Craig:

Here's a complete working Perl script.

# cat .purgelp
#!/usr/bin/perl
use strict;
use warnings;
use Date::Calc qw( Decode_Month Delta_Days );

my $days_to_remove = @ARGV ? $ARGV[0] : 5;
my @requests;
my @fields;
my ( $line, $month, $age );

my ( $currday, $currmon, $curryr ) = (localtime)[ 3, 4, 5 ];
$currmon++;
$curryr += 1900;

@requests = grep {/priority/} `/usr/bin/lpstat`;
for $line (@requests) {

print $line;

@fields = split /\s+/, $line;
$month = Decode_Month( $fields[4] );
$age = Delta_Days( $curryr, $currmon, $currday, $curryr, $month,
$fields[5] );
if ( $age >= $days_to_remove ) {
system("/usr/bin/cancel $fields[0]");
}
}
1;

...run it passing the number of days at which you want to cancel the print job. By default, without specification, the script assumes 5-days. For example:

# ./purgelp 0
remotep-558 root priority 0 Dec 4 14:30
request "remotep-558" cancelled
remotep-559 root priority 0 Dec 4 14:30
request "remotep-559" cancelled
remotep-560 root priority 0 Dec 4 14:30
request "remotep-560" cancelled

Regards!

Great! thanks for the replies...I am not able to install Date::Calc..I am getting the following errors. I do have gcc installed and in the path first.

I know this isn't that relevant, but
Perl is a great tool - but for simple things - why use all that overhead?

My sh script is only 5 lines of code (could be one) and much more efficient (doesn't have to make extra library calss, etc).

Just my 2 cents.

Obivously, no points for this post.

Hi Craig:

It appears that your version of Perl was built using HP's compiler. If you do:

# perl -V

...and look under the section headed "Compiler" you should see that.

You can fetch and install a 'gcc' compiled Perl in the event that you don't have an HP ANSI C compiler available:

don't know why you insist of doing it in perl... but I have some old shell scripts that will do the work for you.

It was working for me many yrs when we spooled on HP-UX, nowadays we use cheap SuSe lnx with cups as spool servers.
Simplifies also administration for non-unix personell which do this via browser...
It's quite expensive to use HP-UX processing for printout.

I used to run the CancelOldPrint script in cron. It ran from one central server and removed print more than 8 days old.
The monthdays, yeardays and ymd2yd is some old hints I picked up some place... It helps calculating age and might be useful for other purpose as well.
