I know grep -C -A -B commands – but I have file that I cannot use any of these options on –
I need to find a pattern/match lets say XYZ once I find the XYZ i need to find first occurrence on YYY above it and assign that to a variable . In example below I want to find the “JELLY” assign it to $VAR1 and then look for the first line that has REC in it and in this case assign the value fish2 to $VAR2 — This is a huge file and each section length starting with REC is different in number line it contains ? Please assist .

Example:

</REC>  this is very "fish1">
    </  test a > 
    </  test b > 
    </  test c  " WHITE" /> 
    </  test w > 
    </  test x > 
    </  test y > 
    </  test z > 

</REC>  this is very "fish2">
     </  test d > 
     </  test e > 
     </  test f "JELLY"  /> 
     </  test d > 
     </  test e > 

</REC>  this is very "fish3">
     </  test o "RED"  /> 
     </  test p > 
     </  test q >
