I am scheduling a command for a specific time every day.
Linux crontab format which I am using :- MIN HOUR DOM MON DOW CMD
30 08 10 06 * /home/mach/script.sh
Some presetting is required?
I have a question about using crontab with /etc/crontab...
I had a cron job that I needed to run as root. At the time I thought that sticking it in /etc/crontab would be a good idea. However, I used the crontab command to edit /etc/crontab, which I guess is not standard procedure? Specifically, I configured /etc/crontab as my local user's crontab (i.e. sudo crontab /etc/crontab) then added my cron job as I would a local user crontab (i.e. sudo crontab -e).
Originally, my cron job looked like this:
30 * * * * root /my/batch/script &> /dev/null
After adding the new cron job I started seeing errors. Something to the effect of "can't find command root" or something similar. So I removed the 'root' user definition from the cron job and the job started running fine. However, because this is /etc/crontab, there are other system related cron jobs that have been defined to run under the root account (e.g. "17 * * * * root cd / && run-parts --report /etc/cron.hourly" runs as root, etc.). So these pre-existing system cron jobs, which up until now have been running smoothly, are now generating "can't find command root" errors. But I think that the system cron jobs _are_ successfully being run someplace because logrotate seems to be working.
So what I _think_ is happening is that /etc/crontab is being run twice: once as the system crontab, and once as my sudoed local user's crontab. When I run crontab -l I see nothing, but when I run sudo crontab -l I can see the contents of /etc/crontab. I am reluctant to delete my sudoed local user's crontab, because then in the process I would be deleting the system crontab, and I do not know how I should restore the system crontab's contents. (I am still not sure as to the most appropriate way to edit the system crontab).
How can I get out of this mess? I want /etc/crontab to go back to the way it was before--running _once_ as the system crontab. As for my new cron job, I'm willing to reconfigure it anywhere so long as I am still able to run it as root. Any ideas? (I am using Ubuntu 8.04 Server LTE)
I know my way around MS Windows much better, but I just don't feel right trying to program something for Android on a Microsoft operating system. I am interested in Android programming so I followed the instructions on [URL] to install the environment on my computer...
I just installed the JDK, SDK, Eclipse successfully (or I assume):
* When I get to Step 4 where I'm supposed to run 'android' it will not run. I get the error message "android: command not found" (I am definitely in the right directory).
** When I double-click it in nautilus, it opens up in gedit. I can set the permissions in nautilus (through the properties - Allow executing file as a program) and get it to work,
i have a site where I need to run a couple of php scripts every day..therefore I was thinking to setup a cronjob to do this. Unfortunately I get a whole bunch of errors trying to do so.
I can execute the php scripts via a command line without problem, one example would be

find /var/spool/mqueue -group abc -exec rm -rf {} ;Using above command , I delete all the files belong to group abc.Now the problem i face is that the this command gives error that some files are missing . And this error occur because after creating list of files, it pass that list to rm -rf but till that time sendmail process queue and some of files disapper from /var/spool/mqueue.
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.

I am trying to run a script called install.sh as follows: I get a jar file, and extract it using the command: unzip filename.jar -D path/to/files then I navigate to that directory where I extracted the files, and run the command: sh install.sh (where install.sh is one of the files that has been extracted in that directory using the above unzip command.) running this command gives me an error:'nstall.sh: command not found.' among other errors in the script ( from that portion of the script that should not even be executed, which is really weird). However, instead of unzipping the jar file, if I just copied the same install.sh file to that folder, and ran the 'sh install.sh' command, the script runs fine.
I write a little script that run top command and clear the output leaving only cpu ram and swap values. If i run the script manually everityng works fine but when i schedule the cript to run every 5 minutes from /etc/crontab all run fine but the output of the top command doesnt appear in the log :

How to break strings of command into multi-lines in crontab? e.g. Code: # the following is a very long a gruesome command to be run at 09:59 Monday to Friday. 59 09 * * 1-5 source $HOME/some-definitions; sh /usr/local/my/long/name/application/bin/hello $(date +\%Y\%m\%d) >>/var/log/my/long/name/application/log/hello.log
I have install RHEL5 and created normal user as "test". When I login as root user, I can run crontab command but when I login as test user, I can't run crontab command and throws error as "cron/test: Permission denied". how to enable crontab command for test user as well?
I have a script: `cd $FILEPATH && patch -i $TMPFILEA2$FILETMPPATH` Variable $FILESPATH is = /tmp/ardiff.AvUUGfOKa2/a/hello/ and Variable $TMPFILEA2$FILETMPPATH is = /tmp/ardiff.AvUUGfOKa2/b/hello/hello.c.patch. I don't know, why is it no working from script file, it write me message to terminal: ./ardiff.sh: line 242: patching: command not found.
But I have no PATCHING command there!!!! The paradox is, when I want to patch it from terminal (I write it to terminal by keyboard, it works).
Either no error and it doesn't run (The scripts all run fine manually and in the cron.daily, cron.hourly, etc. directories.) If it does try to run it, it shows this: Feb 16 12:59:01 buddha crond[3638]: (*system*) BAD FILE MODE (/etc/crontab). Here's my crontab:
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 recently installed Fedora 14 from KDE live CD . everything is working excellent except when I tried to do lsmod today, I got lsmod:command not found error.I checked and found that PATH did have /sbin and /sbin/lsmod does exist. But /sbin/lsmod points to /bin/lsmod (which does not exist)I did whatprovides on lsmod and found module-init-tools-3.11.1-2.fc13.i686 as the package.

I am attempting to create a script for Grid job submissions. I have most of it completed but when testing I've run into some problems.
How it works is that I have 2 wrapper files, one is the top of the script, the other the bottom, the original script imports commands for the middle.
Basically this is what is to happen: cat script-start.sh >> workerscript.sh echo commands >> workerscript.sh cat script-end.sh >> workerscript.sh
workerscript.sh gets created with no problems but when it is run I get: export: command not found
I think that the new script is not calling bash which gives the problem. I don't know how to fix the problem though because I have the shell set in the script-start.sh.
#!/bin/sh - tried /bin/bash, same result export PROJECT=/...... export PROJSOURCE=/......
Using zstyle, I can create a custom warning for messages and such, but looking into the man pages and all, I do not see anything for customizing actual error messages in ZSH, as such:
Code: casper@ltp01[/home/casper][19:14] - asdfsdafasdfjsdf zsh: command not found: asdfsdafasdfjsdf
I have a guy in my office who was using an old version of ubuntu and he tried upgrading to 10 but now he's getting grub error 17. I Google this and everyone suggests reinstalling grub starting with opening a shell and typing 'sudo grub'.
However, I get 'command not found' in response to that. I've tried looking for the location of grub so I could try 'sudo /sbin/grub' and such, but I don't see it anywhere.
Also, I'm using a version 9.10 Live CD at the moment because I can't find out how to disable the drmraid option on the version 10 CD (necessary to detect the hard drives which, although they are on a raid controller are not configured as an array but separate drives).
