How to limit output Show Memory Free Totals using regex

[hfakoor222]

I'm writing a script to get the memory from devices, with show memory free totals i get the below

I only want to get the first two lines to compare free to total memory and write it into an output file if below a certain percentage.

How can I exclude everything after the first 2 lines?

I use the output modifier 'section Head' and it returns:

I can try 

"show memory free totals | include (Processor).*[0-9]"

and it gets me output I want within a single line

However I would like to know is there a way for me to get the first two lines? It doesn't seem like the router has a feature to get the first n lines of an output,  the rest of the show memory free command has a lot of lines, the same with other troubleshooting commands I've come across, and i would like to get the first few lines.

why you not use SNMP OID for this case ? it can give you free used memory
