I need a shell script that would run two .sh files which are in the directory: /opt/tomcat-latest/bin
#!/bin/sh
cd /opt/tomcat-latest/bin
./shutdown.sh
./startup.sh
Would this code achieve my goal? If so how do I make it on a cron job that runs every 2 hours? I have a Linux Centos VPS and DirectAdmin admin panel.
I think the easiest solution would be to run directly the commands with its full path from cron, instead of using a sh script.
Something like this in the crontab would work :
* */2 * * * /opt/tomcat-latest/bin/shutdown.sh && /opt/tomcat-latest/bin/startup.sh
That would run every 2 hours
you can edit crontab with crontab -e and check the crontab syntax here : https://fr.wikipedia.org/wiki/Crontab

Here is my shell script, myscript.sh located in ~/bin
cd ../environment
. env/bin/activate
python3 office.py
The script office.py updates the database. I've tested and works with no issue. I used this command ./myscript.sh
Here is cronjob */5 * * * * cd ~/bin/myscript.sh added to crontab -e
When i check database, no changes. The cronjob isn't running? How do i solve?
You are not running the script but just trying to change directories, which will fail as myscript.sh is not a directory. You need to first cd ~/bin as you are using relative paths in your script and then run the script. Use this line:
*/5 * * * * cd ~/bin && ./myscript.sh
Also you may wanna check the syslog to check for cronjobs.
grep CRON /var/log/syslog
Have a look at this thread for more information on logging cronjobs.
I am running a bash script that transfers files to my AWS bucket.If i run the bash script through my terminal it works fine (via ./myBash.sh).
However I put it in my crontab but there it doesn't work.This is my bash script
#!/bin/bash
s3cmd put /home/anonymous/commLogs.txt s3://myBucket/
echo transfer completed
echo now listing files in the s3 bucket
s3cmd ls s3://myBucket/
echo check
And this is my crontab-
SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
46 13 * * * /bin/bash myBash.sh
And here is a list of things i have aready tried -
1)tried running the crontab with a node app to test whether crontab was working(the answer was yes)
2)tried running the crontab without the SHELL and PATH
3)Tried running the bash script from cron using sudo (46 13 * * * sudo myBash.sh)
4)tried running the bash without the /bin/bash
5) Searched many sites on the net for an answer without satisfactory results
Can anyone help me with what the problem may be?(I am running Ubuntu 14.04)
After a long time getting the same error, I just did this :
SHELL=/bin/bash
PATH=/bin:/sbin:/usr/bin:/usr/sbin
* * * * * /bin/bash /home/joaovitordeon/Documentos/test.sh
For anyone coming to this post.
I was having same problem and reason was crontab was running under root user and s3cmd was configured under ubuntu user.
so need to copy .s3cfg to root
cp -i /home/ubuntu/.s3cfg /root/.s3cfg
I'm running RHEL and I'm trying to set up a cron job to run a shell script every 5 minutes.
Following the directions here: https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Deployment_Guide/ch-Automating_System_Tasks.html#s2-configuring-cron-jobs
I have service crond start and chkconfig crond on. Then I edited /etc/crontab and added:
*/5 * * * * my-user /path/to/shell.sh
I did a chmod +x shell.sh. And I made sure to add a new line character at the end.
I'm expecting it to run every 5 minutes but it never executes.
What am I doing wrong?
Simply try to add the cronjob entry and check the script is working fine or not by taking the viewable output in the script.
echo "test time - $(date)" > script.sh
chmod +x script.sh
crontab -e
Then enter the cronjob as below,
*/5 * * * * sh /path/to/script.sh > /path/to/log.file
Check if the log is writing correctly. If its fine, better cross check the script that you are trying to execute via cron. Otherwise it will be a cron issue.
I have build a bash script that gets .tar.gz files from IMDb and writes to a log file, the script works when run on its own as I can see the folder with the files present, but when I run the script via cron it doesn't work. Would this be due to permissions? I have edited the sudo crontab file, but I'm not sure what else I need to do.
Try this solution:
Cronjob is a file that contains your job:
cat cronjob
* * * * * bash /path/to/script.sh >> /path/to/log.txt
Then you should set executable permission and start cron service:
chmod +x cronjob
/etc/init.d/crond start #redhat based servers like centos
/etc/init.d/cron start #debian based servers like ubuntu
After that you should tell cron service to run cronjob file:
crontab cronjob
Your script should download a file.
If your script doesn't run you should run it from good path[full path], so your cronjob file would be something like this:
* * * * * /bin/bash /path/to/script.sh >> /path/to/log.txt
I'm trying to run a command by cron in Raspbian.
If I run ./sec_cam.sh, than my script runs, If I try to run it via crontab every 5 min, than nothing happens.
crontab -e shows me the followings:
*/5 * * * * ./sec_cam.sh
Did I configure the crontab wrong?
Thx in advance
scripts started from a cronjob are not setup with your usual environment, especially not with your current working directory (referenced by the . in ./sec_cam.sh). so to make this work you should specify a full path name like /home/user/sec_cam.sh
