Shell Script Execution and format o/p error!

Maybe the script puts some output to STDERR instead of STDOUT.
To confirm that, manually run it like this as a test:
    ./ScheduleDevice.sh >stdout.txt 2>stderr.txt
Then show us the output of both files like this:
    head std*.txt

If some of the output is in stderr.txt, you could add "2&>1" to the end of the cron job like this:
    */5 * * * * /usr/local/cronjobs/Java-Files/ScheduleDevice.sh >> /usr/local/cronjobs/Java-Files/ScheduleDevice.log 2&>1

Hello @tel2 thank you for your useful tips,

I have followed your process.... But here script is executing successfully it stores the output into >stdout.txt  file

Here i want to redirect the stdout.txt file o/p into /usr/local/cronjobs/Java-Files/ScheduleDevice.log file ,when  i tried to doing this with cron job it took  the duplicate time and stores into log  .

FYI & R  -- Please find the bold time

Thank you once again @tel2

Q1. Any significant differences?

    Ans:- As i test the "env" command with both scenario (command-line/ inside script) there nothing changes found!
   
Q2, And have you actually tried putting 2&>1 at the end of the cron job command to see if that helps.
    Unlikely, given what you told me, but try it and let me know what happens.

   Ans:- When i tried  "2&>1" with following cron job nothing is printed to /usr/local/cronjobs/Java-Files/ScheduleDevice.log
   */5 * * * * /usr/local/cronjobs/Java-Files/ScheduleDevice1.sh >> /usr/local/cronjobs/Java-Files/ScheduleDevice.log 2&>1
   
Also, could you please run the command I gave in my last post again, and then run:
  wc std*.txt
 
Q3. What is the output?
 [root@vps1 Java-Files]# wc std*.txt
  0   0   0 stderr.txt
  9  32 209 stdout.txt
 10  34 225 total

Please let me know is there anything missed or need to test.

FYI..

Currently i'm executing the ad-hoc script manually it's works fine

[root@vps1 Java-Files]# ./ScheduleDevice1.sh
removeing files
File not Exists..
+ ./ScheduleDevice.sh
+ set +x

Thank You Every one for your Support and Feedback! Much Appreciate

Finally my Cron job working well, i can see the Schedule-device  get append with different timestamp .

FYR.. Which i'm using now as per your instruction.

Thank You Once Again!

Thanks Simon.

Thanks  a Lot @Simon and @tel,  Much Appreciate for your time and valuable comments.

Hi again Mihir,

You remember when I wrote the following, above?:

As a short alternative to this code:
    if [[ "$files" ]]
    then
        echo " $files  found."
        echo "Deleting Exixting files"
        rm $files
    else
        echo "File not Exists.."
    fi
you could simply use something like this one-liner:
    rm -v std*.txt 2>&1

I forgot to say the following line can also be removed if you are using that one-liner:
   files=`find /usr/local/cronjobs/Java-Files -type f -name "std*.txt"`
