Linux BAsh Scripts - Failed

Hi @Inderpreet @kodekloud-support3

Linux Bash script was failed with “ is not found on backup server”. I have also setup passwordless authentication for other server user like app02 app03 to run the scripts without any password. I did everything right, not sure why it got failed. Also i have

Could you please check and let me know what went wrong.

@Rapa If you read the question carefully there is a point:

d. Please make sure script won't ask for password while coping the archive file also respective server user (for example tony in case of App Server 1) must be able to run it.

I think you setup the passworless access from root user (on stspp01) to clint user on backup server however tony user must be able to run the script on app server 1.

Thankyou @Inderpreet

What did i do wrong . backup server has the file



Seems like on stapp02 you did all the testing from user root, as mentioned it the question did you tested it from user sudo user i.e steve in case of stapp02.

This command [steve@stapp02 scripts]$ sudo ./ still means you ran it using user root as you used sudo.
