[request filled] Conky script to get the number of pacman updates

Kooothor · 2008-10-18 22:33:01

Hi everyone,

I'm not very good at scripting but I would like to have something that displays :

UPDATE : 2 new packages

in my conky
All the other pacman scripts I found were too complicated, here I just want to know how many packages are waiting for upgrade.
I already have a pacman -Sy cronified hourly.

How can one manage to do that, any help appreciated !

Regards,

~ktr

Have you tried lyraes?

Kooothor · 2008-10-18 23:09:45

/me don't know what it is....

I take it that you've seen all of these:
http://bbs.archlinux.org/viewtopic.php?id=53761
http://bbs.archlinux.org/viewtopic.php?id=44023
http://bbs.archlinux.org/viewtopic.php?id=37284

You can try this:

#!/usr/bin/perl
use strict;
use warnings;
print ((`pacman -Qu` =~ m/^[^\s]+\s\((\d+)\):/m) ? $1 : 0);

Save it as "list_upgradable.pl", make it executable (chmod 755 list_upgradable.pl), then invoke it to get the number of upgradable packages.

I have some other code snippets to display more info if you want more than just the number of packages.

*edit*
This script does not update the database for you. You need to use cron to do that. Take a look at this post below to see how.

Thanks, it seems to work fine and it's simple !
I'll tell you if it's truly fine when I have something to update !

Thanks, but I'd like to keep it simple

Don't worry, I was just thinking of some simple one-line sentence depending on whether there are updatable packages (e.g. "nothing to update", "1 package waiting for update", "x packages waiting for update").

I'm glad I could help anyway.

Interesting, please post it

Xyne · 2008-10-19 02:02:55

#!/usr/bin/perl
use strict;
use warnings;
my $n = ((`pacman -Qu` =~ m/^[^\s]+\s\((\d+)\):/m) ? $1 : 0);
if ($n == 0)
{
     print "nothing to update"
}
elsif($n == 1)
{
     print "1 new package"
}
else
{
     print "$n new packages"
}

Just change the output to whatever you want.

Thanks this was exactly what i needed.

Nice, thanks

linko · 2008-12-19 16:34:27

Thanks Xyne, nice script.

luuuciano · 2009-06-08 22:26:56

but this needs root access?
or let normal user to run pacman?

No root access needed. This script doesn't actually do anything. Doesn't download or install anything. Just finds out how many packages are avaliable for update.

somehow this script always shows me "nothing to update" until i 'manually' run pacman -Qu in a terminal, which renders it pretty useless

Running "pacman -Qu" doesn't update anything. You must mean "pacman -Sy". The script isn't meant to update the database for you. You need to use cron to do that. Just add a script to /etc/cron.hourly so it gets updated, e.g.

#!/bin/bash
pacman -Sy 1>/dev/null 2>&1

You could also use rebase to update the database if you want to avoid unnecessary writing to the disk.

Btw, for anyone interesting in the script that I posted above, take a look at paconky.

k3ttc4r · 2009-06-10 22:16:39

yeah, pacman -Sy, that's what i meant..

now that you pointed it out to me, i could have gotten it myself
thanks, though!

This script suddenly stopped working for me after working great for months. I call it from .conkyrc with

${execi 30 /home/user/bin/pacman-updates}

with /home/user/bin/pacman-updates being:

#!/usr/bin/perl
## script by Xyne
## http://bbs.archlinux.org/viewtopic.php?id=57291

use strict;
use warnings;
my $n = ((`pacman -Qu` =~ m/^[^\s]+\s\((\d+)\):/m) ? $1 : 0);
if ($n == 0)
{
     print "No new packages"
}
elsif($n == 1)
{
     print "1 new package"
}
else
{
     print "$n new packages"
}

pacman -Sy is in crontab, and pacman -Qu shows the update. All the other conky execi variable stuff is working (lm_sensors, gmail update, etc.) anyone see why pacman script isn't updating??

muchas gracias!

>> edit: small update. I added

chomp ($n);

before the if statement to prevent the last condition from printing out on two lines. current script:

#!/usr/bin/perl
## script by Xyne
## http://bbs.archlinux.org/viewtopic.php?id=57291
use strict;
use warnings;
my $n = (`pacman -Qu | wc -l`);
chomp ($n);
if ($n == 0)
{
     print "No new packages"
}
elsif($n == 1)
{
     print "1 new package"
}
else
{
print "$n new packages " 
}

pacman -Qu | wc -l

Welcome to the forums shura. Please look over the rules, specifically necro-bumping http://wiki.archlinux.org/index.php/For … Bumping.27

This solution was also posted in luuuciano's link above.

Roline · 2010-03-06 12:43:39

Technically i'm not necrobumping right now, anyway. I can't get the cronjob to work. I added the script to the folder /etc/cron.hourly but it doesn't update... Cocky stays at 0 untill I update pacman myself.

tomk · 2010-03-06 19:48:51

Roline - please apply some common sense, and stick to the guidelines. Read the link posted above for full details.

Closed.
