Fedora :: Jobs Command Not Working In F14 ?
Apr 24, 2011I tried using the jobs command in bash in F14 but nothing happens.
Code:
[root@Fedora ~]# jobs -l
[root@Fedora ~]#
Code:
[root@Fedora ~]# which jobs
[Code].....
If jobspec is given, output is restricted to information about that job. The return status is 0 unless an invalid option is encountered or an invalid jobspec is supplied.
If the -x option is supplied, jobs replaces any jobspec found in command or args with the corresponding process group ID, and executes command passing it args, returning its exit status.
Is the jobs command dropped for the ps command instead ?
Programming :: Run Parallel Jobs With Make -j4?
Nov 27, 2010I use an application called redbutton-browser to access some of the things available on the redbutton digital tv channels. It compiles fine if I use a simple make but fails if I try to run parallel jobs with make -j4. I'd like some help altering the Makefile so that it does a few commands sequentially before it does the rest of the Makefile in parallel.
The relevant bit of the Makefile looks like this:
Code:
ISO13522-MHEG-5.c:xsd2c.c ISO13522-MHEG-5.xsd add_instance_vars.conf add_rtti.conf
make xsd2c
./xsd2c ISO13522-MHEG-5.xsd
./add_instance_vars ISO13522-MHEG-5.c ISO13522-MHEG-5.h
./add_rtti ISO13522-MHEG-5.c > rtti.h

Ubuntu Servers :: Cron Jobs At Reboot Not Working
Jul 13, 2010Have a headless server running Lucid 64 bit. Everything is working great except for a couple of Cron jos I'm trying to have run at boot.
My user crontab looks like this:
# m h dom mon dow command
01 * * * * /home/ceallred/Scripts/SambaBkup.sh
@reboot /usr/bin/SpiderOak --headless &The SambaBkup script works like clockwork...
The SpiderOak job doesn't start. It works if I type the command in manually.
syslog only shows:Jul 13 22:45:33 RavenWing cron[1010]: (CRON) INFO (pidfile fd = 3)
Jul 13 22:45:33 RavenWing cron[1022]: (CRON) STARTUP (fork ok)
Jul 13 22:45:33 RavenWing cron[1022]: (CRON) INFO (Running @reboot jobs)
Jul 13 22:45:33 RavenWing CRON[1048]: (ceallred) CMD (/usr/bin/SpiderOak --headless &)Yet ps -A doesn't show a running SpiderOak process. It shows after starting manually.
Programming :: Correct Way Of Spawning Parallel Jobs?
Mar 18, 2010I need to spawn 2 processes in parallel and each takes an hour or so to finish. Is the following one of the correct ways of using `at` in a script run by crontab?

#!/bin/bash
# define the env var, cd, etc... assume everything ok up to this point
date +"The start time is %H:%M:%S"
rm -f a.fin

Programming :: Get Background Jobs To Execute Sequentially?
May 4, 2009I'm looking for a general pointer, or label for what I am trying to do. Not a specific line of code. I've written a couple of small sh script that gets some user input, then calls several programs to run in the background with the &. My problem is, they all run at the same time. Is there some way to get these jobs to run sequentially rather than consecutively? If yes, what is this process called? I'm thinking there should be a way to line up background jobs in a job queue, similar to how a print queue works, one job at a time. After searching for a couple of hours, I'm thinking there must be a name for this, but I don't know what it is.

Ubuntu :: Cron Jobs Don't Run?
May 22, 2011I have this in my crontab (along with another line before it):
Code:
* * * * * /bin/echo "Does this work?" > ~/test
...and the file doesn't show up. I have a blank line after that one in the crontab. I have no /etc/cron.allow or /etc/cron.deny files. I'm running Ubuntu 11.04. /var/log/syslog shows "BEGIN EDIT" and "END EDIT" etc. when I run crontab -e, but doesn't say anything about trying to run commands. Anything I might be missing?
Software :: Rc.d Jobs Not Starting
Feb 4, 2010I just reinstalled linux on one of my computers, and now it seems that any scripts in the rc.d folders don't run at boot. I have to go in manually and start them all after I can get to a terminal. I have webmin running on this computer, and no matter what I do, it always says that nothing is supposed to start on boot, even though the scripts are clearly in their respective rc.d folders. What can I do to fix this?

Ubuntu :: Cron Jobs Not Running?
Jun 2, 2011I have a cron job that executes fine in opensuse 11.4. It is located in
/etc/cron.d/publish.cron:

It is correct, I want it to execute every minute. Now, I copied the same script to ubuntu maverick, and it doesn't run. Perhaps there's some ubuntu peculiarity that I'm not aware of?

CentOS 5 :: Cups Delay Between Jobs?
Nov 16, 2009Since my last server upgrade, last Thursday, cups is having a strange behavior: I have 3 text-only printers, and an application that prints to them. The application, to print 5 lines, it sends 5 jobs to the printer. Before the upgrade, all the jobs where printed sequentially, without any delay. After the upgrade, cups makes a small delay (5s or more) between every one...Its very annoying for the users...

Ubuntu :: Print Jobs Stuck In Queue?

I installed both of the printers via the GUI in Administration, and both of them are detected and Ubuntu says they're working. But when I put something in the queue to print it stays there with the status "pending".
