i want to do scheduling using /etc/crontab file instead of using crontab -e that is crontab command on the terminal.i am appending to the crontab file in the /etc directory but the scheduling is not happening
I have installed an application manager(monitoring application) on my linux server. Now, i need to have backup schedule for my application. The application itself has executive file to backup database.But when i put this file in my crontab to schedule the backup program it wont run!50 09 * * * root /opt/ME/AppManager9/bin/BackupMysqlDB.sh
I am using Linux 64 bit Redhat Linux. I am trying to setup simple crontab as follow...1. Edited crontab file using crontab -e2. Listed the file once to verify it using crontab -l. This will display as.. 18 5 * * 2-3 ksh $HOME/testScript.sh > $HOME/testscript.out3. Logged in a root and restarted cron deamon using "/etc/init.d/crond restart"As per my understanding now my testScript should start running at 5:18 am Thuesday
is it possible disabling a crontab job without deleting the crontab description entry (by crontab -e)?I could also accept to change the entry itself. Now it's:0 0 * * 0-6 /home/me/cron/script.csh
I attempted to run various cron jobs as root - just general server make-tidy stuff. But if I edit the /etc/crontab file directly, these tasks don't get run. However, if I use crontab -e as root, these jobs appear to work. Any idea why this might be the case? Also, I understand that user cron jobs are stored in /var/spool/cron/<user> (including root). If this is the case, what's the purpose of the /etc/crontab file?
I've tried to create a crontab that renames a fil extension every minute. This is what I've tried:*/1 * * * * / rename /home/bodil/Avräkningsfiler/'s/.txt/dat/' *.txtBut it doesn't seem to work.I've also tried to create a .sh file in the catalog itself with the command executing directly in the catalog but even though running the command by typing it in, it doesn't run automatically by cron
I have this code that is 'bashed' regularly with crontab and basically it will send me an E-Mail of most of the output but it misses out some of it!
Here is the crontab code to automatically run the script:
Code:
So that sends me an E-mail with most of the output of the following code:
Code:
It sends me everything up to echo "*******" "Begin compressing and transferring files" "*******" but it wont output the tar bit.. so it should give me a list of files that have been tarred.
I am trying to have the files from /user/directory copy every hour to /backup/user/directory. It would seem that cron or crontab is what I need to use. Looking at previous posts and other documentation only shows how much I don't know. When I type crontab -e I get a blank file I can type into, seemingly using vi as the editor. I have no problem with that but when I type cron -l, I get my text after a message about "Do Not Edit this File". What I am reading just makes no sense, I am not understanding even the most fundamental aspects of cron or crontab. Where I can get the most basic of basic instructions to try to understand this function?
Is been a while since I was last here requesting help. Now I need some of that LQ magic. I have a script file that extracts data for a date range, create a zip file for the data and then ftp it to a remote server. Now the script is working perfectly if it is run manually, but now I want it to execute automatically. So I use the crontab, but for some reason the script fails when run from the crontab.code...
when a script in /etc/cron.d directory will be executed?. I know that scripts in cron.daily will be executed daily [ set in /etc/crontab file]? Cant able to find this directory listed in /etc/crontab file?
is linux kernel is priority preemptive kernel?if it is. where it is using round robin scheduling algorithm?when processes are scheduled for the processor process will be allocated as which sechudling alogorithm?
iam try to schedule my job in a file made in /etc/cron.d file as follows* * * * * tomcat6 /home/etika/Desktop/eka.sh /home/etika/Desktop/ea/etika.txt abc@gmail.comwhere eka.sh belongs to etika which is the root and etika.txt belong to tomcat6 this command is not running iam confused about the name of the owner written after the *'s please tell me whose name is written after the *'s(the schedule of the script) the owner of the script or the owner of the file which iam passing as an argument to the shell script
I have played around a little bit with CGROUPS and the fair group scheduler ( using kernel version 2.6.31). When you have CGROUPS in a flat structure, with only one layer from the root-cgroup, everything works as you might expect when setting the cpu.shares parameter, i.e. a fraction of the total. But when I experimented with having deeper levels of CGROUPs it did'nt make any sense sometimes. For example, I had one CGROUP with the maximum number of shares (260000 something) , and two childgroups with quite little shares, 5000. Then I created some cpuhogging processes ( while(1); ) and put most of them in childgroups and one in the parentgroup. The logical thing would be if the parentgroups single process took almost all CPU-time, as it had the maximum number of shares, but instead the processes in the childgroups got the most CPU-time.
I have tried to figure out how it works by looking at the source code, but I can't really understand it. How does the hierarchical structure of the cgroup-tree interact with the flat aspect of it, i.e. siblings? Or do I misunderstand the whole concept?
am newbie and i have problem to write a scheduling script in java, this script should do something in certain time interval... Could anybody help me, maybe give some example or source that maybe useful
A couple days ago I noticed cron stopped working and now I can't create a new file using crontab -e. When I hit crontab -e I get the editor but after saving nothing comes up under crontab -l and the file is blank when I reopen it. I don't have a cron.allow or a cron.deny.
I am proposing moving from the mainframe to Linux. Problem is that I am not aware of a scheduling product that is available to handle the production code. Currently using CA7. Is there anything out there that accomplishes the same thing? As you can tell, I am NEW to Linux!
I used crontab to set a file playing at a certain time, this works fine; however I want this to run even if no-one is logged in (but the computer is on). I can't get it to do this
Line is: 30 06 * * * env DISPLAY=:0.0 /usr/bin/totem /home/adunaic/Playlist.pls
Okay I think the problem was with needing a GUI.
Using this instead works, but i only hear the sound when I log in. I think something needs to be doen to start the audio perhaps?
I am trying to run rsnapshot from cron via root's crontab file (crontab -e). If I run rsnapshot from the command line with sudo it works perfectly, however, if I run it from cron:
Code: * * * * * /usr/bin/rsnapshot hourly >/tmp/crontab.out 2>/tmp/crontab.err This does not work. The crontab.err file shows:
I am using squid 2.6 on my cent os 5 .I want to shutdown the system at 7:00 pm for that purpose I write in# crontab -e 0 19 * * * /sbin/shutdown -h nowThe thing which I want to clear that when the system will going to turn off it will also stop squid service? If not then how can I automatically stop squid service and then crontab file execute
when I type "crontab -e" to edit the file, it is not opening in the editor & showing output as "285". I just wanted to edit crontab, So could anybody please tell me which is the real file of crontab, so I can manually edit that file using vi editor or nano. Or if that default editor is corrupted when I type "crontab -e", how can I change default editor before using "crontab -e" command. I will be waiting for your kind reply
