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?

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
echo $(date +"%m-%d-%Y_%T") "Certificates where copied, restarting server" >> $logFile
docker restart $containerName

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" ]
Long story short I am trying to have my aws userdata create a cronjob on launch. I am unable to echo into the /etc/crontab location. Here is a snippet of my code.
echo '# description of cronjob being addeded'
echo '0 16 * * 2,4,6 root some commands' | sudo tee -a /etc/crontab > /dev/null
echo ' ' | sudo tee -a /etc/crontab > /dev/null
Here is the Answer incase someone else needs to know.
"sudo sh -c 'echo \"# description of cronjob being addeded\" >> /etc/crontab' \n",
"sudo sh -c 'echo \"0 16 * * 2,4,6 root some commands\" >> /etc/crontab' \n",
"sudo sh -c 'echo \" \" >> /etc/crontab' \n",
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

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
