It seems an easy task to suspend a computer in command line i search through the net and find this:
I want to suspend my computer at a specific time when im away from home but i have 2 problems in cron that i could not solve it yet.
1- it needs user password (how can i embed the password?)
2- it needs to press a key before suspend.( i want to suspend automatically) ubuntu 10.04.1
Just curious if this is possible. What I want to do is setup a rsync job to backup my laptop to my personal file server(same LAN), but I want it do do this at 3AM while I'm sleeping. However I always close my laptop lid when I'm done using it which puts the laptop into suspend mode since that's how I configured my power options in gnome. Since I don't want to leave my laptop powered up all the time, I was wondering if it is possible to have a cron job scheduled that will wake the laptop up(out of suspend mode) and run my script/backup job, all without opening the lid of the laptop, and then put it back into suspend mode when it's done. Is this possible, and is it as easy as scheduling a cron job or is there some other scripting/configuration/trickery that I need to do to accomplish this?
Also, my laptop's BIOS has the option to power on at a scheduled time if needed, but I'm not sure if that would work with it being suspended(hibernation is not an option since my entire HD is encrypted with LUKS and I would have to be present to enter the password to boot the system.).
Can anyone tell me how i change the default domain name for cron?everything i cron runs it emails from and to user@com.com
this leaves me with a massive list of failed mails in postfix.i have mailto on my main crontab but i cant do it on all of them.
It seems that cron is not upgrading my Ubuntu 8.04 LTS Server, no GUI installed. I changed /etc/crontab and watched apt running:
Code:
ps -A | grep apt
showed it for a long time,
Code:
sudo tcpdump tcp
showed communication with canonical sites,
but:
Code:
top
did not show any apt using CPU

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.

View 1 Replies View Related3 questions i have about "pm-suspend-hybrid"
1. is it possible to schedule this command in the same manner as shutdown ? eg sudo shutdown -h 60
2. is it possible to schedule the laptop to come out of suspend ?
3. i have a usb sound card (xfi go). when waking from suspend, the internal sound card is selected. i have to manually select the external sound card & for whatever reason, also unmute it too
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 have set up a cron in /var/spool/cron/root
*/15 * * * * /usr/bin/phplist.sh
I can see in /var/log/cron that it is running every 15 minutes but it has no effect. It is not doing the commands in the bash script.
If I run /usr/bin/phplist.sh right in the shell it works great.
Is my vixie-cron broken? i have "0-59 * * * * root /usr/sbin/logrotate /etc/logrotate.conf" but it is not running in /etc/cron.d.

Just got Ubuntu 9.10 and I'm liking it a lot, but my computer refuses to go into hibernate or suspend. I have a Dell M1530 but I don't really think it's a dell hardware issue because it's not just when I close the screen, it's also when I click suspend or hibernate from the menu.

## cifro un fichero
/usr/bin/gpg --encrypt --batch --no-tty --yes --recipient Mypubkey /home/joseba/salida.txt > /home/joseba/logcronjob.txt
#EOF
If I use the line
joseba@server$ /usr/bin/gpg --encrypt --batch --no-tty --yes --recipient Mypubkey /home/joseba/salida.txt > /home/joseba/logcronjob.txt
I dont have problems, salida.txt has encrypted
But by crontab -e (for user joseba) dont work and dont encrypt nothing If I use 'sudo crontab -e' same result, dont work
Mypubkey exists
On logcronjob.txt nothing, 0 bytes I think env its ok for the users
I've been trying to accomplish this on my own, but I can't seem to figure it out...
All I'm trying to do (for learning purposes) is to get a message to print out to a log file every 5 minutes.
This is on Ubuntu Server 6.06.
Logged in as root ( I know, I know, should have sudo'd, oh well... )
Created a new file with this in it:
Code:
Added this line:
Code:
( I wasn't sure the proper command to try every 5 minutes, but this is my latest iteration. I also started with just */5, and that didn't seem to work either. )
Saved and exited crontab.
Console reports:

So I waited 10 minutes to be safe.... and saw no log file appear.
I checked this page here: [url]
I wasn't sure what it meant by the PATH= variable they wanted me to set, my /etc/crontab file states:
Code:
But I didn't know if it meant there, or in my crontab -e location, so after the first failed attempt, I added the line from that webpage as well to crontab -e:
Code:
Waited another 10 minutes to be safe, still nothing.
why my second cron job isn't running? The first one runs fine but the second one does not run at all. If I manually run the script using ./check.sh then it does what it is supposed to but will not run from cron. It should run every weekday at 9:45am, it looks good to me but clearly I am doing something wrong.
Code:
# m h dom mon dow command
#This will backup my hosted websites.
0 2 * * * /home/bob/scripts/websitebakscript.sh
#This will run check and upload it's contents to the net.
45 9 * * 1,2,3,4,5 /home/bob/scripts/check.sh
I'm trying to set up my pc to power off at 00:30 everynight. I'm using webmin's Scheduled Cron Jobs tool. I've tried (running as root):
halt
shutdown -h now
and neither have powered off the pc using webmin. Am I missing something?
How do I run a script in cron? would I do it like this:

Cron refuses to work for a newbie.I am trying to setup a cron job to backup a folder in my home directory ('/home/scratch') to a folder ('home/internet_backup') that is mounted (using nfs) to a network folder.the folder ('home/internet_backup') is mounted correctly to the network folder upon system startup, so this part works.

I have a working bash script to do backup - it runs fine from the terminal. During the backup it makes a log file in my home area. I transferred it to root, and set it up to run as a cron job as root. It runs fine as long as I am logged in with my normal user name. It does not run if I am not logged in. Logs show the script was called by cron, but there is no output and no backing up is done.
Here is the script

I am making a webpage which is to be automatically generated every minute. I've created a cron job in crontab like this:
Code:
0-59 * * * * /usr/bin/php /var/www/site/updatestatistics.php > /dev/null
When I refresh the page 'updatestatistics.php' in my webbrowser it does generate a new page ('statistics.html', which is included in 'statistics.php'). But when I let this cron job do the job, nothing happens. I looked into the log file, it shows this:
Code:
(root) CMD (/usr/bin/php /var/www/site/updatestatistics.php > /dev/null)
I have this symlinked into my /etc/cron.d folder:
Code:
*/5 * * * * python /srv/bidsite/manage.py send_mail
* * * * * echo `date` >> /home/bidsite/what.txt
but it does nothing. What I really want to happen is the first line. The second line is just for testing.
After saving a few sample scripts in crontab, I discovered that cron is not running properly on my Ubuntu 9.10 (32 bit), after a recent reinstallation. Please note that the files "/var/log/cron" and "/etc/defaults/rc.conf" are empty in my system.
View 4 Replies View RelatedI'm trying to get this script, which normally works fine, to run from cron. This is far from my first custom cron script, but it's the first to give trouble! I've added PATH directives (never had to do that before) but it still didn't work. I also tried setting absolute paths, that didn't help either. If I add a line that echoes a string to a file as a test at the end of the script, the file appears, so I know the script is executing, it just looks like the cpufreq-set commands aren't working. The purpose of this script is to adjust the maximum SpeedStep setting on my now passively-cooled home server to keep the CPU from getting too toasty.
Code:
#! /bin/sh
PATH=/sbin:/bin:/usr/sbin:/usr/bin:/usr/games:/usr/local/sbin:/usr/local/bin
# set temp above which to drop the maximum frequency
scaledowntemp=`echo -n "62"`
# set temp below which to reset the maximum frequency
scaleuptemp=`echo -n "59"`
# get cpu temperature
cputemp=`sensors | grep "Core 0" | gawk '{print $3 }' | sed -e 's/+//g' | sed 's/....$//'`
if [ $cputemp -lt $scaleuptemp ] # if temp is in acceptable range, set max frequencies free
then
cpufreq-set -c 0 -u 2.81Ghz
cpufreq-set -c 1 -u 2.81Ghz
fi
if [ $cputemp -gt $scaledowntemp ] # if temp is too high, limit cores to 1.6Ghz
then
cpufreq-set -c 0 -u 1.61Ghz
cpufreq-set -c 1 -u 1.61Ghz
fi
I 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?
I've setup a cron job to run every day at 13:00. When I run it manually it works but with the cron it doesn't

the *.sh are executable. I logged out and logged back in since I put the cronfile in crontab. The commands that I use in the *.sh files work fine when I run them manually.
I seem to be having a problem with cron. I have a python program that checks a specific directory for pending email scripts written in python.
Code:
#!/usr/bin/python
import os
emaildir = os.environ['HOME']+"/email/"
filelist = os.listdir(emaildir)
for pyfile in filelist:
if pyfile.find(".py") > -1:
execfile(emaildir+pyfile)
This code has been tested and works fine. The problem is that I need cron to run this code every 5 minutes but i can't tell if it is running: Here is my cron code:
5 * * * * /home/username/custom/CheckEmail.py >>/home/username/custom/email.log 2>&1
I activated the log (I think) but all i get is /var/log/cron.log and that only logs when I activate/deactivate or edit the cron file. is there anything else i need to set for this to work? I am running Ubuntu 9.10.
Where the cron tables are stored?
IE crontab -e (or -l)
and
the system one :-
sudo crontab -e (or -l)
I need to retrieve them from a system backup, don't know where to look.
When I run this this script in bash it works perfect. When I run as a cron job it starts but never finishes. The reason I know it starts is because a temp file is started by zip but never is completed.The funny thing I was running Linux Mint 8 and this worked fine I just switched to Ubuntu 10.04 & bang no good ..
Crontab -l Output -->
# m h dom mon dow command
