Crontab runs a script on UNIX

Question

Have a simple script to run the top comman nand to save the result in a txt file. He will start the cycle 3 times a day with a 1-hour interval. After that, the email will be sent using the contents of the text file as the body of the email and delete the text file so that a new text file appears the next day.

Problem

• To automate the process, I created a cronjob to start at 8:30 pm, which will run the script, and my script will continue to run for 4 hours, and the result of the command will be added to the text file and finally sent by mail. CRON is →0 10 * * * /tmp/ssh-abc/KKK/Report.sh

  /tmp/ssh-abc/KKK/Report.sh: line 34: ReportProd.txt: Permission denied

The code

To create a txt file

{
//Some Logic
} >> ReportProd.txt   //Running script manually works great and generate txt!!

Delete the file after distribution.

find /tmp/ssh-abc/KKK/*.txt -type f -delete   //This works fine manually,file is getting generated and deleted also.
