here the below code for creating cron jobs successfully but i need to prevent duplicate entry so next time i'm trying to create cron jobs for same file. i need to overwrite existing cron jobs
#!/bin/bash
crontab -l > cd3.new
file1="/home/admin/Desktop/n_com.sh -EI"
file2="/home/admin/Desktop/com.sh -NI"
file3="/home/admin/Desktop/fcom.sh -EF"
file4="/home/admin/Desktop/fcm.sh -NF"
echo "$1 $2 $3 $4 $5 $file1" >> cd3.new
echo "$6 $7 $8 $9 ${10} $file2" >> cd3.new
echo "${11} ${12} ${13} ${14} ${15} $file3" >> cd3.new
echo "${16} ${17} ${18} ${19} ${20} $file4" >> cd3.new
cat cd3.new
crontab cd3.new
I like the idea of setting up directories for each "period" of cron, and using run-parts to execute them. Updating just requires rsync-ing the new cron directories and there's no chance of messing up crontabs.
And then I setup directories and a crontab as such:
# Run hourly, daily, weekly, monthly and yearly tasks for axon
00 0 * * * run-parts /etc/cron/midnight >/dev/null 2>&1
01 * * * * run-parts /etc/cron/hourly >/dev/null 2>&1
02 1 * * * run-parts /etc/cron/daily >/dev/null 2>&1
55 23 * * * run-parts /etc/cron/dailyend >/dev/null 2>&1
45 2 * * 6 run-parts /etc/cron/weekly >/dev/null 2>&1
02 0 1 * * run-parts /etc/cron/monthly >/dev/null 2>&1
03 0 1 1 * run-parts /etc/cron/yearly >/dev/null 2>&1

i have a problem with a script, when is executed from cron the script does not work as expected but when i execute it from ssh it runs as is supposed.
Setup: QNAP NAS
The script that i'm trying to run:
#!/bin/sh
log="/share/CACHEDEV1_DATA/Jobs/logs/"
currentDate=$(date +"%m-%d-%Y")
logFile=$log"SSLCertNextCloud_"$currentDate".log"
certSource="/etc/stunnel/"
certFile="backup.cert"
certKey="backup.key"
nextCloudCert="/etc/apache2/ssl/SSLcertificate.crt"
nextCloudKey="/etc/apache2/ssl/SSLprivatekey.key"
nextCloudSSLFolder="/etc/apache2/ssl/"
containerName="NextCloudServer"
if [ "$( sudo docker container inspect -f '{{.State.Status}}' $containerName )" == "running" ]
then
echo $(date +"%m-%d-%Y_%T") $containerName "is up and running" >> $logFile
else
echo $(date +"%m-%d-%Y_%T") $containerName "is not running, trying to start" >> $logFile
docker start $containerName
sleep 20
status=$( sudo docker container inspect -f '{{.State.Status}}' $containerName )
echo $(date +"%m-%d-%Y_%T") "Status:"$status >> $logFile
if [ $status == "running" ]
then
echo $(date +"%m-%d-%Y_%T") $containerName "started successfully" >> $logFile
else
echo $(date +"%m-%d-%Y_%T") "Could not start " $containerName >> $logFile
fi
fi
if [ ! -f $logFile ]
then
touch $logFile
fi
if true | openssl s_client -connect myserver 2>/dev/null | \
openssl x509 -noout -checkend 0;
then
echo $(date +"%m-%d-%Y_%T") "Certificate is not expired, exiting" >> $logFile
else
echo $(date +"%m-%d-%Y_%T") "Certificate is expired, copying new certificate" >> $logFile
docker cp $certSource$certFile $containerName:$nextCloudCert
docker cp $certSource$certKey $containerName:$nextCloudKey

The problem is when the script is executed from cron i get the following output:
03-25-2021_21:00:00 NextCloudServer is not running, trying to start
03-25-2021_21:00:20 Status:
03-25-2021_21:00:20 Could not start NextCloudServer
03-25-2021_21:00:20 Certificate is not expired, exiting
It seems that it does not get a status, if i connect via SSH to the NAS and run that script, it works as designed
03-23-2021_00:00:01 NextCloudServer is up and running
03-23-2021_00:00:01 Certificate is not expired, exiting
The fix to my issue was to set the full path to docker.
e.g:
docker=/share/CACHEDEV5_DATA/.qpkg/container-station/usr/bin/docker
if [ "$( $docker container inspect -f '{{.State.Status}}' $containerName )" == "running" ]
I'm creating a cron job in a script like this:
DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"
crontab -l > crontask
grep "* * * * * $DIR/somescript" crontask || echo "* * * * * $DIR/somescript" >> crontask
I'd like to build a script that can delete this job, how should I do that?
If I schedule my cronjob to work with minutes (*, */5 etc) the cronjob is executing. Working with hours, the cronjob doesnt seem to work.
This is my list of cronjobs:
* * * * * /path/to/script/ swiftmailer:spool:send --env=prod >> /path/to/cron.log 2>&1
* * * * * /path/to/script >> /path/to/cron.log 2>&1
0 0 * * * /path/to/script >> /path/to/cron.log 2>&1
*/3 * * * * /path/to/script >> /path/to/cron.log 2>&1
0 0 * * * /path/to/script >> /path/to/cron.log 2>&1
0 0 * * * /path/to/script >> /path/to/cron.log 2>&1
0 0 * * * /path/to/script >> /path/to/cron.log 2>&1
The ones at midnight are not running. If I change
*/3 * * * * /path/to/script >> /path/to/cron.log 2>&1
to
0 * * * * /path/to/script >> /path/to/cron.log 2>&1
that particular script will also stop running.
If I set all the scripts to run every minute, there are no errors in the cron.log.
how is this possible?
I would like to know how to extract the state of crontab.
Currently I have these lines, with the execution off:
crontab -l
#* * * * * cd $HOME;sh .bash_profile >/dev/null 2>&1;cd /home/gisdesa/GIS/DESA;. ./loader_DESA.sh
#* * * * * sleep 15 && curl cd $HOME;sh .bash_profile >/dev/null 2>&1;cd /home/gisdesa/GIS/DESA;. ./loader_DESA.sh
#* * * * * sleep 30 && curl cd $HOME;sh .bash_profile >/dev/null 2>&1;cd /home/gisdesa/GIS/DESA;. ./loader_DESA.sh
#* * * * * sleep 45 && curl cd $HOME;sh .bash_profile >/dev/null 2>&1;cd /home/gisdesa/GIS/DESA;. ./loader_DESA.sh
Desire, based on the state of the crontab for these lines, report ON or OFF in a log file.
In this case I must report "OFF"
Instead:
crontab -l
* * * * * cd $HOME;sh .bash_profile >/dev/null 2>&1;cd /home/gisdesa/GIS/DESA;. ./loader_DESA.sh
* * * * * sleep 15 && curl cd $HOME;sh .bash_profile >/dev/null 2>&1;cd /home/gisdesa/GIS/DESA;. ./loader_DESA.sh
* * * * * sleep 30 && curl cd $HOME;sh .bash_profile >/dev/null 2>&1;cd /home/gisdesa/GIS/DESA;. ./loader_DESA.sh
* * * * * sleep 45 && curl cd $HOME;sh .bash_profile >/dev/null 2>&1;cd /home/gisdesa/GIS/DESA;. ./loader_DESA.sh
In this case I must report "ON"
They can help me with any ideas?
Thanks
crontab -l | awk '{if($0~/^ *#/){ print "OFF: " $0 } else print "ON : " $0 }' \
> cronStatusReport.$(/bin/date +%Y%m%d.%H%M)
should produce the output you're looking for.
output (from reduced set of your data)
OFF: #* * * * * cd /C/Users/Neil_2;sh .bash_profile >/dev/null 2>&1;cd /home/gisdesa/GIS/DESA;. ./loader_DESA.sh
OFF: #* * * * * sleep 15 && curl cd /C/Users/Neil_2;sh .bash_profile >/dev/null 2>&1;cd /home/gisdesa/GIS/DESA;. ./loader_DESA.sh
ON : * * * * * sleep 30 && curl cd /C/Users/Neil_2;sh .bash_profile >/dev/null 2>&1;cd /home/gisdesa/GIS/DESA;. ./loader_DESA.sh
ON : * * * * * sleep 45 && curl cd /C/Users/Neil_2;sh .bash_profile >/dev/null 2>&1;cd /home/gisdesa/GIS/DESA;. ./loader_DESA.sh

I'm new to linux and I'm learning to script an alarm clock using bash and cron. The script works fine from bash and by double clicking on it, but not from cron; as soon as cron calls the script, the alarm sounds once (one loop, it seems) and then stops without even showing the dialog box (zenity). I'm using Linux Mint 13 Maya XFCE.
Here is my crontab setup
* * * * * /home/x/Documents/MyScripts/Cron/BeepAlarm "Wake Up"
And here is my script
!#/bin/bash
# Initialize Variables
Text=$1
Title="Alarm"
OkLabel="Snooze"
CancelLabel='Shut It Up!'
Icon=/home/x/.icons/actions/48/appointment-new.png # Won't work
SnoozeTimeout=120
AlarmCycles=100
shopt expand_aliases
alias vol='amixer -q -c 0 sset Beep'
vol 25% # Heart friendly
rm -f LoopMode # Just in case =P
# Dialog Box Function
_MsgBox () {
if zenity --question --title="$Title" \
--window-icon=$Icon --ok-label="$OkLabel" \
--cancel-label="$CancelLabel" --text="$Text"
then
echo 1 > LoopMode
else
echo 2 > LoopMode
#kill -TERM `jobs -p` # Won't work
fi
}
# Alarm Loop
while [ $AlarmCycles -gt 0 ]; do
case `cat LoopMode` in
"") # Question Box
echo 0 > LoopMode
_MsgBox &
;;
1) # Snooze
vol 25%
rm -f LoopMode
sleep $SnoozeTimeout
;;
2) # Stop Alarm
break # But don't sleep again
;;
*) # Get on my nerves
beep -r 4 -l 20 -f 2000; sleep 0.5
beep -r 4 -l 20 -f 4000; sleep 0.5
AlarmCycles=$((AlarmCycles-1))
vol 5%+
esac
done
# Housekeeping~
kill $(($!+2)) # I don't know a better way to kill zenity Dialog
vol 25% # =)
rm -f LoopMode
As Rob suggested:
* * * * * env DISPLAY=:0.0 /home/x/Documents/MyScripts/Cron/BeepAlarm "Wake Up"
P.S: Sorry, I didn't pay attention to the formalities
