oops, just playing around! sorry!

To create a service that can be used via upstart, I just need to create a script in /etc/init.d/ and do a update-rc.d <script>, is that right?

yes, but native upstart jobs are in /etc/init

for upstart jobs no update-rc.d is needed - its filename just has to end with ".conf"

Basically, I want to run some stuff, and want to be able to shut it down, both via upstart. atm, I kill it manually by ps ax-ing and grep-ing it, and killing it using the pid. I guess I can put all the starting and killing in a script, but thats not a good idea. What do you think, @htorque

sure, you can do this in upstart scripts, but i don't know how :P

yeah, ill figure that out ;) just needed to ask if that was correct!

just make it a question and wait for the answers coming in ;-)

10:26 AM

if you say so!

Q: Want to make an upstart script; need help and advice.

Atm, I need to randomly start and stop (for lack of a better word in my mind) a job. I start it by typing java -jar foo.jar and to stop it find out its pid and kill it. Killing it doesn't cause any data loss or corruption or anything, just FYI. Its tedious to do both these steps because the first...

service upstart

@htorque i just told my mom about and you, and u have your 2nd fan :P

11:13 AM

@htorque why do you get all the fans?

@KaustubhP Posted an answer

@Oli because there are two(!!!) posts related to me on OMG! Ubuntu! - what else to expect from life? :P

hello all :)

9 Power_On_Hours          0x0032   092   092   000    Old_age   Always       -       12346588876956059

i don't think that's right :D

@StefanoPalazzo hello! :-)

@htorque SMART?

@Oli yes, S.M.A.R.T. on a SSD

11:21 AM

@htorque Hmm yeah the last time I checked my OCZ's SMART data it was all over the place

@Oli how do you keep track of power-on time? or just "don't care"?

I'm just checking mine, all of the data seems to be correct

@StefanoPalazzo is it an OCZ one?

@htorque Mine is on all the time... I could just compare it to a mechanical disk if I really want to know

it's a kingston one

11:22 AM

probably an OCZ thing then

and it's on almost as long as I have it, 18.5 days

@Oli yeah, my script looks similar ;) paste.ubuntu.com/555361 I think i only messed up the run levels.

"Head Flying Hours: N/A" (:

@KaustubhP As I say in the post, you might not even want the start command, if you just want to start it from the command like when you need it

"Head Crashes: N/A" :D

11:24 AM

That's reassuring

@Oli Just didnt add the su -c bit because it will go on a debian system that i ssh into. Is it possbile to not end up in a root shell after ssh-ing?

never had such a wonderful experience - i always replace my hard drives after 10.000 power-on hours... let's see how this works with SSDs :)

@htorque apparently the newer smartmontools can decipher what the ocz drives really mean

@Oli will give it a try, thanks!

@htorque I bet this is all a myth and that this ssd won't break until I throw it out anyway (I've got 120 euros riding on it, hehe)

11:29 AM

Hmm no apparently 5.39 should do (Maverick's is 5.40)

I have a raw value of 8355 for Power_On_Hours

Although I've seen that raw values tend to mean very little

But I've probably had it for a year... so that would make sense

the disk utility should show you power on hours in human readable form

9 Power_On_Hours 0x0000 --- --- --- Old_age Offline - 8355 from smartctl

powered on "unknown"

maybe it's a 64-bit thing?

will try a 32-bit cd :)

or maybe it's broken - it doesn't make any noise! :D

And the entry in palimpsest (seriously, who came up with that name?!) is 163-32-0-N/A which seems a lot further off

temperature 1°C - what a cool piece of hardware!

11:36 AM

I don't see any temperature on mine :(

I'm getting bored of mine... Considering trying to justify a PCI-E SSD to the better half

Whoa. You can get a 120gig Revo drive for only £220... That's a lot cheaper than it's been

"the faster my data loads the more time i'll have for you" (yeah, sure!)

I like it!

My mouth is watering at the prospect of 480MB/s-540MB/s

Deleted -- Forgot I could edit posts

reads a full cd in a bit over a second :D

And if I'm getting that, I could probably justify an i7 980X

Hmm maybe not... Bank account might implode

nope, same with 32-bit

11:50 AM

@Oli extremely sorry to interrupt. I restarted the system, and I still cant access the job.

codeomnitrix

hii all can anyone tell me how to install ati graphics driver in ubuntu

@KaustubhP How are you trying to start it?

codeomnitrix

hey oli can you please tell me how to install ati graphics driver in ubuntu

`sudo service job start`
`start: Unknown job: job`

@KaustubhP Just saw your comment on the post. You don't need update-rc.d

@KaustubhP And what's the name of the /etc/init/...conf script?

11:59 AM

@Oli I also created a file by the same name (the name is job) in /etc/init.d/ and the job now shows up in autocomplete

@codeomnitrix Sorry - I moved to Nvidia hardware when I moved to Linux.. ATI isn't my area, I'm afraid

@codeomnitrix is this a fresh install of ubuntu?

codeomnitrix

ya

@Oli ok

@KaustubhP ya this is a fresh install of ubuntu

@codeomnitrix check this link https://help.ubuntu.com/community/BinaryDriverHowto/ATI
https://help.ubuntu.com/community/RadeonHD

smartmontools from trunk works fine

12:00 PM

@KaustubhP Well it should be in /etc/init/ if you want it to be called job (not sure I'd recommend that because it's confusing) it should be /etc/init/job.conf. And then start job should run it. You shouldn't need to restart.

@htorque cool... it give extra information now?

i'll check if ubuntu's smartmontools isn't configured to include a drive database to interpret the raw values

not extra information, but correct one :)

Just as good =)

ohk, ill rename it to something more readable. but I still get the no such job error/

@KaustubhP Well I just tested this and it works here

oli@bert:/etc/init$ sudoedit /etc/init/myjob.conf
**pasted in my script**
oli@bert:/etc/init$ sudo start myjob
myjob start/running, process 1865

@KaustubhP Are you using an old version of Ubuntu?

@Oli its 10.04

12:07 PM

Hmm that should work just fine

Although I can't test because all my machines are either 9.10 or 10.10

@Oli Tried again with a diff name, and these contents, still the same error. your code worked fine though.

paste.ubuntu.com/555376

@KaustubhP You mean when you used my script it worked fine?

I think you can only have one exec line

Yes, I only changed the java part at the end to a echo statemnt. I got a message saying the job has started, but did not get the echo.

If you want to do more than one thing, either wrap it in something like su -c "..." or bash -e "..."

Or use a script block instead of exec

See: upstart.ubuntu.com/getting-started.html

Under Writing Jobs

I have seen that documentation, and thats why i am more flummoxed, that I have done everything as mentioned, and I still cant get it working

12:20 PM

@KaustubhP Oh that's probably because it's suppressing the echo... I think there's another command to have it output to the console

yeah last bit in Writing Jobs

exec echo example
console output

That might output to TTY1 if you don't see it in your current xterm

@Oli yeah, iremoved the two lines, now it works. :p

added a console output but still dont see a output, i think that needs to be looked into//

@KaustubhP Looking at the docs, it's not quite as simple as it looks... You might have to manually wire it to a running console

But you could easily have it echo something to a new file: `exec echo "RAWRW" > /root/test

@Oli also, ~ doesnt work in the file/ I have to give the full path.

@KaustubhP Yeah that goes without saying... It's not running in bash after all

Oh. I didnt know that. :/

Well, the good news is the pre-script is working. but the java part isnt

12:33 PM

try using its full path: /usr/bin/java

Anybody running KDE?

@Oli yes, used the full path, also since it use the -e flag, it was exiting. I fixed the jar and now its running.
