Need to find a string, check the next line, and if it matches certain criteria, replace it with a s
Hey Fellas.

I am new to scripting. I have searched through the forums and found a lot of good info, but I can't seem to get any of it to work together. I am trying to find a particular sting in a file, and if the next string matches certain criteria, replace it with a string from a csv file. Roughly about 1500 times in the file. I have been trying to do this with awk/sed, but i haven't had the best of luck.
example:
find the string that starts with data7
if the string on the next line has the word prisoner then replace it with the string in line one on the csv file.
the next instance of the pattern would be replaced by the string in line 2 of the csv file. and so on.
the word prisoner appears multiple times in the file, but i only want to replace the ones that directly follow the string containing "data7"
does this make sense?

When i say i'm brand new to scripting i mean BRAND new. I'm taking some classes, but i need to get this done as soon as possible and what i have learned so far hasn't gotten me much closer. any help ya'll can give would be greatly appreciated.
Thanks!
