[SOLVED] Find between patterns and process between patterns

Find between patterns and process between patterns

I have a file format like below,

####################### FILE Content ###################

Path 1
AND cell
OR1 cell
BUFF1 cell
OR2 cell
Ends

Path 2
OR1 cell
BUFF1 cell
AND1 cell
AND2 cell
BUFF2 cell
OR2 cell
Ends

Path 3
AND1 cell
AND2 cell
AND3 cell
OR1 cell
Ends

##########################################

I need output like below:

Path 1 - BUFF* count 1

Path 2 - BUFF* count 2

Path 3 - No BUFF

By using sed i can first get the Pattern to Pattern like. sed -n '/Path/,/Ends/p' Further to get the Ouput after that, i need your expertise help. can someone help me please.

Thanks GB

Solution

You might use awk and use patterns to check if you are between Path followed by a digit and Ends.

When it matches Ends print the current Path you are in and the count of BUFF's.

Then reset the variables seen and buff.

awk '
/^Path [0-9]+/{seen=1; buff=0; path=$0; next}
{
  if(seen && $1 ~ /^BUFF[0-9]+$/){++buff;}
}
{
  if(seen && $1 ~ /^Ends$/){
    print path " - " (buff ? "BUFF* count " buff : "No BUFF")
    seen=0; buff=0    
  }
}
' file

Output

Path 1 - BUFF* count 1
Path 2 - BUFF* count 2
Path 3 - No BUFF
