Ubuntu :: Can't See Results Of Job Scheduled With The 'at' Command
Oct 5, 2010
I scheduled a job, 'ls -a', with the at command, 3 minutes in the future. It looks like the job ran, but I cannot see the results of 'ls -a'. I accessed my mail with the 'mail' command and saw that the output of my scheduled job was message 1. I typed in '1' after the & prompt, and saw that the subject of the message was the output of my job, scheduled at the time specified with the 'at' command. I cannot see the output of the 'ls -a' command that I scheduled though. How do I see the contents of the message, and the actual output of the job.
I'm timing how long it takes to run a command foo. I'm looking to append the results from the time command to a file, and discard the results from the foo command. I tried the following, but it didn't do what I want:
$ time ./foo > /dev/null >> output_from_time_command.txt
i wonder if it is usual that the results of running commands via the command line is different from running them in a script file. my problem is that, i've to run 'modprobe -r e100' and 'modprobe e100' before suspend my machine via pmi in order to resume it properly. i wrote a script containg EXACTLY the same commands as i typed in the terminal/console but the result was not the same. the machine cannot be resumed as expected if i run the script file.
When I shutdown my server it seems to lock up. I use ssh for a headless unit and I can reboot fine, but I told it to shutdown and disconnected me and stopped logging (as far as I can tell) and then nothing. The lights stayed on and I had to press the power button. Is there a way to keep the logger running or to look someplace other then messages. I'm not great with logs.
I'm trying to send the results of a command line $du --max-depth=1 to a zenity message box.I want to create a .sh script that I can run as a Nautilus script that will open a zenity message box with a listing of sub-folders/sizes. $DU with options, will provide the results in a terminal window, but I can't seem to get it into a zenity message box. I've tried gxmessage also, but no go.
Below is an example output of what I see when I run the 'ls' command on some directories in linux (this is from a tomcat/common/lib directory). However I'm not clear on why some of the filenames are appearing inside [square brackets]
This question may be silly and super easy for linux connaisseurs, but I was just wondering, for instance, I want to use the >find command to search for a file and send the results to a text file
how to include my command results in a script? Basically what the script does is it checks the status of a service within the linux server, then sends an email when done. I want to include the results of my status check to my mail when sent.
i.e. service dhcp3-server status Status of DHCP server: dhcpd3 is running. <---this I want to include in the mail that is sent out via script.
I wanted to supply mplayer with the output of find command as arguments. The error returned showed spliced names of files whenever spaces occurred. I have subdirectories in my /home/my_user_name/Music/ directory, and in them multiple *.oga music files. The actual command that I issued was
mplayer started but then was looking for broken file names. I am thinking quoting has to do with it to preserve the filename as one string but different attempts were met with inroads:
Code: mplayer `find /home/my_user_name/Music/ -name "*.oga"` gave me the same result and Code: mplayer `"find /home/my_user_name/Music/ -name *.oga"`
I am trying to get the correct CPU usage using top. I ran collectD and I got different results.This especially happens when the CPU usage is close to 100%.Has anyone experienced having the top command report different results than other CPU usage utilities?
I've run the command "sudo apt-get update" from terminal, showing no update to do.Then I've run the update manager (System-Administration-Update Manager) and it has shown an update (adobe flash).I thought that "apt-get update" command and update manager were the same... Why do I have different results ? Is something missing in my "sources.list" file ?
Bash acts weird in 10.04 server. Whenever I try to run .sh scripts, every empty line in the script results in "command not found". Then on even simple scripts I get syntax errors, but the same exact scripts work on my 9.10 desktop installation. There's also another problem, I'm not really sure if it's bash-related. After setting the proxy using
I use Kaffeine to record live TV to disk for later playback. I've been putting up with Kaffeine's little foibles for the last little while, but tonight (for the second night in a row) I accidentally closed it and consequently it didn't record anything.
Is there any software I can use to construct a recording schedule which will then not be dependent on me remembering to leave a particular app running? I don't really need this in MPEG4 or anything. The PC stays on 24x7 - I just need it to launch a recording at the correct time.
I've avoided MythTV in all it's incarnations because I want the computer to still function as a normal PC most of the time, and from my admittedly brief trial of MythTV it took over the PC and wouldn't let me open a web browser or a mail client.
i have made a search on this subject and i always find the cron to be the solution for me. But i am asking because i think what i want can be done differently. i have a command line to grab stream and save it. i want this command to be run at different time (hours) on specific days. i should use the "at", as far as i saw here on the forum. But are there other way to do it? can i have a simple script that i run the day of the event, before this occur?
i was reading on how to do scheduled tasks, however i couldnt find anything that was a scheduled task to copy a whole folder to a NAS(Network Storage) thats linked on my ubuntu desktop every 4 hours or so.
I have my background as a satellite picture of the earth. Right now I have a scheduled task to grab that picture off the internet (the website updates it every three hours) so my background is a 'live' snapshot of the earth.
I want to set up a scheduled task to take a screen shot every three hours, so that I can see, for example, the way the earth changes over the course of a day...a week, etc. I already have the Scheduled Task Manager from Gnome, but would anyone know what command I could use to do this?
My biggest problem is figuring out how to change the name of the picture it saves it as every time. (e.g. earth1.jpg, earth2.jpg, earth3.jpg, etc.)
I am trying to get Scheduled Task to run a bash script (which runs an rsync command) but it does not seem to be running. I can run the script from the command line with out a problem, but I have it scheduled in Scheduled Tasks to run once everyday and I can't find any evidence of it running or any indication why it does not run. is there a better GUI for scheduling tasks? I am running 10.04 server with xbuntu desktop
When I try to launch it from the System Tools sub folder, I see it appear for a second and then it disappears. What should I do? This is the code displayed when I try running it from the Terminal.
Basically what I wanted to know is, if we turn the computer off (or hibernate/standby) - what will cron do with the tasks that were suppose to be scheduled during that time period the moment u turn it back on? Reason I ask is because i have a backup scheduled for every single hour. And another one I want to schedule for every 15mins. If I turn my comp in standby overnite, I certainly don't want to turn it on in the morning to find cron doing like 30 back up jobs!
I am running a series of operations on executable matlab scripts which are connecting python and fortran scripts. I schedule the executables in cron. The problem:
- My original matlab scripts work perfectly. - My executables work perfectly if I run them from the terminal. - Using the gui scheduled tasks and running the scripts once from a button, everything also works fine. - But when I leave the scheduled tasks run on their own, I get an error! The error can be that the script hangs in general (I have some text logs exported every step to track the progress), or I get an error which never appears when I run the script with any of the other mentioned ways. - I tried both cron command prompt or the GUI scheduled tasks - I am running on Ubuntu 64 bit
I am looking for an automated backup system and I like bacula. I have 3 Notebooks and a Desktop computer that need regular backup. Now I don't want to let them run all night just to do the backuping, so I was thinking I could use wake-on-lan to have bacula wake up the machines, then do the backups, and shut them down afterswards. While this may work with devices on the ethernet, it won't work with the Notebooks on the wifi. So is it possible to have the Notebooks schedules to automatically wake up from suspend or shutdown ? Or is it possible to interject a shutdown command if it is after a cerain hour and call the bacula director to start the backup now?
I've been trying to use gnome-schedule to create a scheduled task that would dial my pppoe connection automatically. For this I used "sudo pon" command (after configuring the pppoe connection using pppoeconf ). Although the command gets executed, but then it waits for me to enter the password. I want it to be automatic & shouldn't require me/anyone to authorize it. Is there a way to enter this password automatically for the scheduled tasks?
Also, I'd like to use network manager, instead of pppoeconf, for the same purpose. How can I set network manager to dial a pppoe connection at scheduled time?
I have network shares automounted in /media and I want to exclude them from my automatic scheduled ClamAV scan in Maverick. How do I do this? I can't find any CRON link or script that actually starts the scan. Is it the Daemon that does this?
I run a Fedora 9 server at home, to host an "old school" MOO.To back up the database, I scheduled a cron job - and got some help with the script.I don't fiddle with stuff on the server much, because I don't really have a clue - leave well enough alone.But now I'm without backups. (I'd prefer to get this working, as it seemed pretty simple, and worked well for so long).
Got a small problem, I'm trying to schedule a script to run every Thursday at midday and the scheduled tasks application on Ubuntu doesn't seem to work. The script is fine when I run it from a terminal.I have zero experience using cron at the command line, can anyone tell me what I should do?
I have webmin on my linux server, I've made a cron job which requires a password to be entered after the command has been run.. all good. I noticed the cron job has the option "Input to command", where after many hours googling a can assume this is where you type input after the cron job has run (for example, a password?). I have tired putting the password needed for the job (the cron job is an ssh root@address) into this field however the output when running the cronjob is saying "permision denied" still.
Is there some sort of character I have to enter in this field, like -p mypassword: or *mypassword? or "mypassword"
