so sorry about this seemingly silly cron question. I know a lot are asked, and are usually just environment related.Anyway, I wrote a very simple PHP script to mount my external drive to a specific location as soon as it's switched on.The script works great when run.What's strange, is that it runs in cron and generates a log file, but for someone reason doesn't mount the drive when cron runs itI added in the full path to EVERYTHING in the script, and I'm calling it with the full path from crontab, but it doesn't mount my drive when run from cron.I've tried running the individual commands on the cmd, and it all works.
I am adding the following scripts to cron via crontab -e (as user)
Quote:
The first one is to record tv. I've added dev/null 2>&1 at the end. No too clear why but without it, it records only a few seconds.
The second script is (as you should already noticed) to turn off my computer at 6:25 am. It doesn't work (with or without dev/null 2>&1). I am surely forgetting something important. Could you please tell me what is it?
I'm trying to add several cron jobs. I have a folder (/etc/cron.myapp) with several subfolders in it (30minute, 3minute, daily, hourly). Each of these folders contains a script.Runnng/usr/bin/run-parts /etc/cron.myapp/3minute/will execute the contents of that folder.I have tried adding the following entries to /etc/crontab with no luck, and nothing is showing up in /var/log/cron
I wanted to use cron to play a media file at a certain time (i.e. use it as an alarm clock). However it seems to do nothing. The contents of my crontab is:
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 put in my cron entries to run my backup script which rsyncs my data to my 2nd drive, however on a hunch I checked my backup drive which mounts automatically via fstab and I realize it had not ran in a while. I checked cron and there were no entries for it. I got to wondering if I should ever be worried about a cron update coming down and over-writing my existing cron file with the backup entries in it to run.
I have added some executable scripts to /etc/cron.daily but don't get the stdout/stderr output from them as mail (or anywhere else I have found). At least one of them is running (because I can see that it has added a file to the disk).
The peculiar thing is that I do get the output from /etc/cron.daily/0logwatch (part of the logwatch package) as an email each day.
The MAILTO line in /etc/crontab is "MAILTO=root" (unchanged from default). Same for /etc/anacrontab.
I do have an alias at the end of /etc/aliases which redirects root's mail to my own account, but this alias works fine for mail I send manually. (It also appears to work fine for the output from the file /etc/cron.daily/0logwatch.)
I am a xfce user. I have a list of wallpapers and I wanted to change them every 5 minutes Initially I was using a simple command in crontab entry to change it, Quote: */5 * * * * xfdesktop --reload it was working but it would crash xfdesktop process after few changes and the screen would be all grey. To solve this issues I wrote a simple script which would check if xfdesktop is alive and if yes it would call xfdesktop --reload else start xfdesktop I called this script idesktop & its path is ~/.bin/idesktop
I successfully installed and validate ns-allinone-2.34 network simulator on ubuntu-9.10. I then tried to run simple tcl code and ended up on the following error. I couldn't move ahead from there. What should I do to make 'nam(version 1.14)' work on my ubuntu 9.10?
ns: finish: couldn't execute "nam": no such file or directory while executing "exec nam out.nam &" (procedure "finish" line 7) invoked from within "finish"
Here is the code I tried to run (for reference): #Create a simulator object set ns [new Simulator] #Define different colors for data flows (for NAM) $ns color 1 Blue $ns color 2 Red #Open the NAM trace file set nf [open out.nam w] $ns namtrace-all $nf #Define a 'finish' procedure proc finish {} { global ns nf $ns flush-trace #Close the NAM trace file close $nf #Execute NAM on the trace file exec nam out.nam & exit 0 } .....
By the way I googled and got some suggestions like: adding 'nam' directory to environment. I did this as follow but it didn't work. I added: export PATH=$PATH:/home/elias/ns-allinone-2.34/nam-1.14 to /etc/profile (>sudo gedit /etc/profile)
I cannot seem to find what I need to in either these forums, Ubuntu help, or various Man pages.Issue:When I insert a CD it automounts correctly, but I cannot Use the "Open with Wine" option (even after configuring wine to recognize the executable) due to a "trust" issue within Ubuntu. I have learned that this "trust" is simply the executable bit, but I obviously cannot change that bit on a read only medium. he software requires the CD at both install and run time, so I cannot use a separately mounted ISO.Somewhere there must be a setting where I can turn off the "require trust flag" which I assume must exist.
After downloading any program thats in ubuntu or uses wine to run before i can run it i've got to allow it to execute, is there a workaround for this? Im using 10.04 ubuntu desktop
Code: ryan@TehLaptop:~$ uname -a Linux TehLaptop 2.6.35-22-generic #35-Ubuntu SMP Sat Oct 16 20:36:48 UTC 2010 i686 GNU/Linux ryan@TehLaptop:~$ lsb_release -a

I have it in my system -> preferences -> startup applications as the command "/etc/init.d/fixkeys" however it is not being executed at startup (I have to manually run the script every time I login). If I manually run it, it works perfectly. I have tried moving it to a directory in my home folder but that did not solve anything.
I installed wine in the new Ubuntu 11, but when i right click and go open with wine it says that its not marked as executable! then i went right click and properties and under the permissions i clicked "Allow executing file" but it keeps unchecking!
Is there any way to map a shell script to run when you press a certain set of keys? For instance, I may want to execute the following by pressing CTRL+ALT+R (if that key combination is not already taken)
Code:
compiz --replace --loose-binding ccp
Or perhaps I want to open the System Monitor by pressing CTRL+ALT+DEL (a la Windows)
I created a script, named mount_share.sh (in /etc/init.d), to mount the shared VirtBox dir at boot so I don't have to do it manually every time I load the VM. The script contains the following:
#!/bin/sh sudo mount -t vboxsf -o uid=1000 osx_shared /home/rob/ubuntu_shared
I made it executable:
sudo chmod +x mount_share.sh
Then I assigned it to run at startup:
sudo update-rc.d mount_share.sh start 51 S .
I'm thinking it may be either:
1) A pathing problem to the ubuntu_shared dir but, if I run "ls -al" from inside /etc/init.d, it does find the ubunt_shared dir
2) Trying to run as sudo from inside the script. But, since all startup scripts run as the root user, I shouldn't even need the "sudo" in there which I have tried to no avail.
I upgraded karmic to lynx today and I'm stuck with some weird behaviour with one of my virtual hosts. The virtual hosts under /var/www/site work but my virtual host for DAVICAL which points to /usr/share/davical/htdocs/ doesn't.
Navigation to any html pages works but php files just show up blank!
Has there been a configuration change in lynx for virtual hosts outside of /var/www?
when I try executing a file in WINE that was a C++ and was compiled into a .exe I get:
