$crontab -e
* * * * * /root/cronJob.sh >> /root/cronJobExecuted.log

Source: cronJob.sh
sh /root/scheduledJob.sh

Source: scheduledJob.sh
One of my web application will keep on insert list of ssh command in my file "scheduledJob.sh" such as
ssh -i key.pem root@<host1> -C sh /mnt/monitor.sh >> /root/Output.txt
ssh -i key.pem root@<host2> -C sh /mnt/monitor.sh >> /root/Output.txt

In remote machine,
Source: monitor.sh
echo `cat /mnt/imageOutput.txt`

Source: imageOutput.txt
line1
line2

As soon as when ssh get executed in scheduledJob.sh, I should not execute it again.
How is should handle this...

Example:
Cronjob has executed 1) ssh -i key.pem root@<host1> -C sh /mnt/monitor.sh >> /root/Output.txt
and 2)ssh -i key.pem root@<host2> -C sh /mnt/monitor.sh >> /root/Output.txt

Again when cronjob trying to execute, it should skip the above 2 ssh command , it should execute only the new command if and only if exist....How i can handle this ?

ssh accept "yes" in automation script possible ?

With the help of ssh i am executing the script...

Before executing the ssh command, at very first time i need to do ssh manually and typing "yes" to accept RSA key fingerprint...Can we do it through automation by passing yes as an argument...

$
The authenticity of host 'hostname (xx.xx.xx.xx)' can't be established.
RSA key fingerprint is 83:71:28:7c:55:38:28:4e:9e:51:32:57:19:9e:d2:d9.
Are you sure you want to continue connecting (yes/no)? yes

With the help of ssh i would like to execute script and redirect the output in my local file

$ssh -i keypair1.pem root@<host> -C sh /mnt/monitor.sh >> /root/imgManagementOutput.txt

source: monitor.sh
echo `cat /mnt/imageOutput.txt`

Source: /mnt/imageOutput.txt
line1
line2

Expected Output:
line1
line2

Actual Output:
line1 line2

I am looking for the output should be as "Expected Output" as it is not in a single line...

Thanks for your info.

Please note ,

1) The key is available. I can able to ssh(login) successfully with the help of key
2) ec2-create-volume is a command in $PATH

What may be the issues ?

As you said i tried with following option,

1) added "#!/bin/sh" in myScript.sh

ssh -i key.pem root@<host> -C "sh /root/myScript.sh"
[color=]Output: File not found: ''[/color]

2) $ssh -i key.pem root@<host> -C "/bin/sh ec2-create-volume --size 10 --availability-zone us-east-1a"
Output: File not found: ''

As you said i treid with following command,

$ssh -i key.pem root@<host> -C /root/myScript.sh
Output: File not found: ''

In remote machine, $ls -rtl myScript.sh
$-rwxr--r-- 1 root root 59 May 30 12:31 myScript.sh

Source: myScript.sh
ec2-create-volume --size 10 --availability-zone us-east-1a

Note: I can able to manually execute the command "ec2-create-volume --size 10 --availability-zone us-east-1a" successfully
If i want to execute the same with ssh via script, how i should procede. Please help me on this.
