I have several configuration files, line starting with line has an IP address

My Read from the target line that starts with the line word from the file and prints the IP address only

The problem is that the IP address can be in any field in the line, so I According to the IP can not capture

example

  grep LINE file1.txt LINE /home/Ariate/run.pl "Voda Stis 4 Test - "" 102841 "& amp; Amp; Ssh 17.77.170.130-P2022 grep LINE file2.txt LINE /home/Ariate/run.pl 137.77.170.30 "Voda STS 4 Test -" "102841" & amp; Amp;  
 Expected Result  
  
  
  Resonance $ IP_Fom_Line 17.77.170.130 Echo $ IP_Form_Line 137.77.170.30  <
