Question about Cron [SOLVED]

thatnewyorker · 2010-05-20 05:42:43

For certain reasons I want to automate my system so it does "pacman -Sy" every hour.

I wrote a little bash script as root, used chmod 700 to make it executable and stuck it in /etc/cron.hourly/

This is the script:

#!/bin/sh

exec pacman -Sy

Will this work?

I think so

fukawi2 · 2010-05-20 08:28:01

Yes

Are you guys sure? It doesn't seem to be working.

Well you just need to do the following command to understand what pacman is actually doing

man pacman

(Using man will give a lot of information on different functions.)

In your case if you want to update your whole system everyhour you should use sonething like -Syu and as you want it to run in background you should ask him to be quiet. I let you find this option in man ^^

But doing such a thing is quite risky in my opinion, because you might and will miss useful information about package. If you relly want to do this output the stdout of pacman to a file, by using something like this

pacman > test.log

Who is the owner of the file? If is not root, I don't think that will work.

Edit: I re-read your post and I see you created it as root. You might check that none-the-less

I don't want to automatically update the system, just refresh the package list. I'm using Awesome window manager and have vicious widget that shows me how many updates I have available by using pacman -Qu. I figure its practically useless unless I have pacman -Sy running regularly in the background.

Is the cron daemon running?
Review /var/log/cron.log

Nevermind guys, I figured it out. Thanks for the concern though:D

@thatnewyorker:
First of all, it would be nice if you could let us know what you did to solve your problem.
Secondly: If your question is answered, please mark your threat as [SOLVED] (just edit your first post).
Thanks.

Anyway, you may also try the following:

-- Pacman widget
pacwidget = widget({ type = "textbox" })
    vicious.register(pacwidget, vicious.widgets.pacman,
    function (widget, args)
        if args[1] == 0 then
            return "<span color='#a2bbff'>Nothing</span>"
        else
            return "<span color='#a2bbff'>" .. args[1] .. " Updates</span>"
        end
    end)

pacwidget:buttons(awful.util.table.join(
    awful.button({ }, 1, function () awful.util.spawn (terminal ..  " -e sudo clyde -Sy" ) end ),
    awful.button({ }, 3, function () awful.util.spawn (terminal ..  " -e sudo clyde -Syu" ) end )
    )
)

pacicon = widget({ type = "imagebox" })
    pacicon.image = image("/home/jack/.config/awesome/icons/pac18.png")
    pacicon:buttons(pacwidget:buttons())
