How to automate and get to the end of more command in a Unix script?

Thanks for your help, I am writing a Unix script to automate a 3rd party script. Inside the 3rd party script I must press the space bar to page down a couple of times and then sign a user agreement, and this happens every time I execute the script. So I wanted to create another Unix program to automatically page down and then once it gets to the "Y/N" then it could just agree automatically.

Listed below is the commands I used but did not work for me:

yes | script_name.sh

echo "y" | script_name.sh

script_name.sh | echo "yes"

Any help would be appreciated thank you again.

Third Party Code:

#

# Copy customer.profile to tmp directory

#

if [ -f "${HOME}/customer.profile" ]; then

    cp ${HOME}/customer.profile ${EMC_TMP}/customer.profile

fi



# 

# Copy legal notice to tmp directory

#

cp ${HOME}/EMC_LEGAL_NOTICE.txt ${EMC_TMP}/EMC_LEGAL_NOTICE.txt

I take it that script_name.sh is a stand-in for the 3rd party script? It would be helpful if you could provide a pared-down version of that script that does the more and any surrounding relevant commands to demonstrate that part of the problem you're trying to solve.

The MORE environment variable can set default options for the more command. Helpful options might be -num <lines> sets the number of lines in a page and +num start displaying at line num. I don't think I have used more since the late 1980s but its replacement less will ignore input from pipes as a security feature so I imagine a modern more might be the same.

@StephenP Thanks for helping me Stephen, The actual name of the third party script I am trying to run is called "emcgrab.sh" and it is for a Linux machine. I am providing you with a URL to a basic idea of what the application does it terms of what the user sees. raghuramnaidu.blogspot.com/2016/04/… However, as soon as a launch the script it prompts me to page down just before I get to the line requiring me to accept the terms and copnditions.

@tharriott you need to include some code in your question as Stephen suggested. Links go dead or get replaced with different content. I'm sure its mentioned in the help center. What the user sees is not important. The exact invocation of the more command is. We can't address what we can't see.

@NiallCosgrove OK, I provided the most relevant part of the code from the 3rd party .sh file.I attached it uptop. However, I realize it doesn't say anything with the more command in it. Thought it calls to a txt file called "EMC_LEGAL_NOTICE.txt" where the actual terms of agreement resides.

Solution depends on the script_name.sh.
I tried the following script:

seq 400 | more

read -p "Do you accept? "

echo "Nice, you replied $REPLY"

When the more is called without path, you can use

alias more=: ; echo y |source ./script_name.sh; unalias more

if the OP ran ./emcgrab.sh -h he would get command line options to bypass the EULA. Nice hack using alias btw.
