You can get more detail by running it as bash -x YourScriptNameHere.sh.

I did not have an issue running your script with a few modifications.
You are downloading 6.4.2 and your install file is labeled 7.2.6. This may be your issue if that is in fact that exact script your running. However, I do not think you would make it past the tar command if that were the case.

There was no l accepting license issue that I ran into.
I tested this on 6.4.2 and 7.2.6 without issue.

My testing was two aws amazon linux boxes that I setup root ssh keys with since your running sudo ssh at the bottom.
I created the student account as well and file permissions looked fine.

Hello Som,

I pasted the wrong line for the download. Yes, I was able to download and install Splunk Ent.
Did the edit password for you?

Thanks

The password in the 6.4.2 version did work
I did notice that the password did not update for 7.2.6 however

I know splunk changed from admin:changeme to your admin password will be created when splunk is installed. I forget which version, but is that way in 7.x.

So I am thinking if you had written this script for 6.x it will not work the same in 7.x

Here is the documentation for 7.2.6 which is not using the ./splunk edit user command any longer:
https://docs.splunk.com/Documentation/Splunk/7.2.6/Security/Secureyouradminaccount

And you can see in Splunk 6.4.2 it still was:
https://docs.splunk.com/Documentation/Splunk/6.4.2/Security/Secureyouradminaccount

I would work towards adopting the new method if you are planning on using 7.x going forward.

It is getting a little late for me to spin up my AWS again, but if you are still stuck by tomorrow I could probably do that and run the commands in the 7.2.6 version to see exactly how to update it.
