get data from text - last line

RouterOS General
1

Hello ,
I have a question about getting data from text file
I want to get the last line of the GPS file - the one that give me the number of satellites
up until now I use this command :

:global speed [:pick $gpstext [find $gpstext "speed:"] [find $gpstext "destination-bearing"]];

:global dstB  [:pick $gpstext [find $gpstext "destination-bearing:"] [find $gpstext "true-bearing"]];

how do I do it for the “satellites” ?
after the satellites I have only number - so I can’t tell him what is the end

example :

      altitude: 70.199997m
 
               speed: 0.203720 km/h
 
 destination-bearing: none
  
       true-bearing: 0.000000 deg. True
    
 magnetic-bearing: 0.000000 deg. Mag
            
    valid: yes
         
  satellites: 7

?

thanks ,
